CAT,[1] properly the name of the well-known domesticated feline animal usually termed by naturalists Felis domestica, but in a wider sense employed to denote all the more typical members of the family Felidae. According to the New English Dictionary, although the origin of the word “cat” is unknown, yet the name is found in various languages as far back as they can be traced. In old Western Germanic it occurs, for instance, so early as from a.d. 400 to 450; in old High German it is ŏchazza or catero, and in Middle German kattaro. Both in Gaelic and in old French it is cat, although sometimes taking the form of chater in the latter; the Gaelic designation of the European wild cat being cat fiadhaich. In Welsh and Cornish the name is cath. If Martial’s cattae refer to this animal, the earliest Latin use of the name dates from the 1st century of our era. In the work of Palladius on agriculture, dating from about the year a.d. 350, reference is made to an animal called catus or cattus, as being useful in granaries for catching mice. This usage, coupled with the existence of a distinct term in Gaelic for the wild species, leaves little doubt that the word “cat” properly denotes only the domesticated species. This is confirmed by the employment in Byzantine Greek of the term κάττος or κάττα to designate domesticated cats brought from Egypt. It should be added that the αἴλουρος of the Greeks, frequently translated by the older writers as “cat,” really refers to the marten-cat, which appears to have been partially domesticated by the ancients and employed for mousing.

As regards the origin of the domesticated cats of western Europe, it is well known that the ancient Egyptians were in the habit of domesticating (at least in some degree) the Egyptian race of the African wild cat (Felis ocreata maniculata), and also of embalming its remains, of which vast numbers have been found in tombs at Beni Hasan and elsewhere in Egypt. These Egyptian cats are generally believed by naturalists to have had a large share in the parentage of the European breeds, which have, however, in many cases been crossed to a greater or less extent with the European wild cat (F. catus).

One of the features by which the Egyptian differs from the European wild cat is the longer and less bushy tail; and it has been very generally considered that the same feature is characteristic of European domesticated cats. According, however, to Dr E. Hamilton, “the measurement of a number of tails of the [European] wild cat and of the domestic cat gives a range between 11 in. and 14½ in., the longer length being quite as often found in the wild cats as in the domestic. The bushy appearance depends entirely on the length of the fur, and accords with the thick fur of the rest of the body of the wild cat, while in the domestic race the fur both on the body and tail is thinner and softer.”

Possibly those domesticated cats with unusually short and bushy tails may have a larger share of European wild-cat blood; while, conversely, such wild cats as show long tails may have a cross of domesticated blood.

More importance was attached by Dr A. Nehring of Berlin (SB. Ges. Naturfor., Berlin, 1887) to the colour of the soles of the hind-feet as a means of determining the relationship of the domesticated cat of Europe. According to his observations, in the Egyptian wild cat the pads of the toes are wholly black, while the black extends back either continuously or in long stripes as far as the calcaneum or heel-bone. In the European wild cat, on the other hand, the black is limited to a small round spot on the pads, while the colour of the hair as far back as the heel-bone is yellowish or yellowish-grey. Since in all domesticated cats retaining the colouring of the wild species the soles of the hind-feet correspond in this particular with the Egyptian rather than with the European wild cat, the presumption is in favour of their descent from the former rather than from the latter.

Later, Dr Nehring (op. cit. 1889) came to the conclusion that the domesticated cat has a dual parentage, one stock coming from south-eastern Asia and the other from north-eastern Africa; in other words, from a domesticated Chinese cat (itself derived from a wild Chinese species) on the one hand, and from the Egyptian cat on the other. The ordinary domesticated cats of Europe are, however, mainly of African origin, although they have largely crossed, especially in Germany (and probably also in Great Britain), with the wild cat. The same author was likewise of opinion that the domestication or taming of various species of wild cats took place chiefly among nationalities of stationary or non-nomadic habits who occupied themselves with agricultural pursuits, since it would be of vital importance that their stores of grain should be adequately protected from the depredations of rats and mice.

The foregoing opinion as to the dual parentage of our domesticated cats receives support from observations made many years ago by E. Blyth, which have recently been endorsed and amplified by R.I. Pocock (Proc. Zool. Soc. London, 1907). According to these observations, two distinct types of so-called tabby cats are recognizable. In the one the pattern consists of narrow vertical stripes, and in the other of longitudinal or obliquely longitudinal stripes, which, on the sides of the body, tend to assume a spiral or sub-circular arrangement characteristic of the blotched tabby. This latter type appears to be the true “tabby”; since that word denotes a pattern like that of watered silk. One or other of these types is to be found in cats of almost all breeds, whether Persian, short-haired or Manx; and there appear to be no intermediate stages between them. Cats of the striped type are no doubt descended from the European and North African wild cats; but the origin of cats exhibiting the blotched pattern appears to be unknown. As it was to a cat of the latter kind that Linnaeus gave the name of Felis catus, Pocock urges that this title is not available for the European wild cat, which he would call Felis sylvestris. Without accepting this proposed change in nomenclature, which is liable to lead to confusion without any compensating advantage, it may be suggested that the blotched tabby type represents Dr Nehring’s presumed Chinese element in the cat’s parentage, and that the missing wild stock may be one of the numerous phases of the leopard-cat (F. bengalensis), in some of which an incipient spiral arrangement of the markings may be noticed on the shoulder.

As to the introduction of domesticated cats into Europe, the opinion is very generally held that tame cats from Egypt were imported at a relatively early date into Etruria by Phoenician traders; and there is decisive evidence that these animals were established in Italy long before the Christian era. The progeny of these cats, more or less crossed with the indigenous species, thence gradually spread over Europe, to become mingled at some period, according to Dr Nehring’s hypothesis, with an Asiatic stock. The earliest written record of the introduction of domesticated cats into Great Britain dates from about a.d. 936, when Hywel Dda, prince of South Wales, enacted a law for their protection. “The Romans,” writes Dr Hamilton, “were probably the original introducers of this cat, and as the final evacuation of Britain by that nation took place under the emperor Valentinian about a.d. 436, the period of its introduction may certainly be dated some 500 years previous to the Welsh chronicle and even much earlier.” It is added that the remains of cats from Roman villas at Silchester and Dursley are probably referable to the domesticated breed.

Before proceeding to notice some of the different types of domesticated cats, a few lines may be devoted to the wild European species, F. catus. Beyond stating that in colour it conforms very closely to the striped phase of domesticated tabby, it will be unnecessary to describe the species. Its geographical range was formerly very extensive, and included Great Britain, France, the Netherlands, Switzerland, Germany, Bohemia, Hungary, Poland, Transylvania, Galicia, the Caucasus as far as the Caspian, southern Russia, Italy, Spain, Greece, Rumania, Bulgaria, Servia, and portions of central and northern Asia. “At the present time,” observes Dr Hamilton, “the wild cat has become almost extinct in many of the above districts. Examples may perhaps occasionally still be found in the uninhabited forests of Hungary and Transylvania, and occasionally in Spain and Greece, as well as in the Caucasus and in some of the Swiss cantons, but the original race has in most countries interbred with the domestic cat wherever the latter has penetrated.” In Great Britain wild cats survive only in some of the Scottish forests, and even there it is difficult to decide whether pure-bred specimens are extant. Remains of the wild cat occur in English caverns; while from those of Ireland (where the wild species has apparently been unknown during the historic period) have been obtained jaws and teeth which it has been suggested are referable to the Egyptian rather than to the European wild cat. Such a determination is, however, extremely hazardous, even if it be admitted that the remains of cats from the rock-fissures of Gibraltar pertain to Felis ocreata.

The favourite haunts of the wild cat are mountain forests where masses or rocks or cliffs are interspersed with trees, the crevices in these rocks or the hollow trunks of trees affording sites for the wild cat’s lair, where its young are produced and reared. In the Spanish plains, however, the young are often produced in nests built in trees, or among tall bamboos in cane-brakes. “To fight like a wild cat” is proverbial, and wild cats are described as some of the most ferocious and untamable of all animals. How far this untamable character lends support to the view of the origin of our domesticated breeds has not yet been determined. Hares, rabbits, field-mice, water-rats, rats, squirrels, moles, game-birds, pigeons, and small birds, form the chief food of the wild cat.

Apart from the above-mentioned division of the striped members of both groups into two types according to the pattern of their markings, the domesticated cats of western Europe are divided into a short-haired and a long-haired group. Of these, the former is the one which bears the closest relationship to the wild cats of Africa and of Europe, the latter being an importation from the East. The striped (as distinct from the blotched) short-haired tabby is probably the one most nearly allied to the wild ancestors, the stripes being, however, to a great extent due to the European wild cat. In one direction the tabby shows a tendency to melanism which culminates in complete blackness, while in the other direction there is an equally marked tendency to albinism; grey cats, which may be regarded as tabbies whose stripes have disappeared, forming the connecting link between the tabby and the white cat. A mixture of the melanistic with the albinistic type will of course give rise to parti-coloured cats. A third colour-phase, the “erythristic” or red, is represented by the sandy cat, the female of which takes the form of the “tortoise-shell,” characterized, curiously enough, by the colour being a blend of black, white, and sandy. The so-called orange tabby is one phase of the erythristic type.

As to long-haired cats, there appear originally to have been two closely-allied strains, the Angora and the Persian, of which the former has been altogether replaced in western Europe by the latter. That these long-haired cats have an ancestry, to some extent at any rate distinct from the ordinary short-haired breeds, is practically certain, and it has been suggested that they are derived from the “manul” cat, or Pallas’s cat (Felis manul), of the deserts of central Asia, which is a long-haired and bushy-tailed species with comparatively slight striping. The fact that in tabby Persians the body-markings are never so strong as in the short-haired breeds is in some degree confirmatory of this, as suggesting descent from a nearly whole-coloured type. At the present day, however, Persians exhibit nearly all the colour and pattern types of the short-haired breeds, the “orange Persian” representing the erythristic phase.

Turning to the tailless or so-called Manx cats, in which the tail should be represented merely by a tuft of hair without any remnant of bone, it seems that the strain is to be met with in many parts of Russia, and there is a very general opinion that it originally came from Japan or some other far eastern country. Throughout Japan, China, Siam, and the Malay countries, normal long-tailed cats are indeed seldom seen. Instead of these are cats with more or less abbreviated tails, showing in greater or less degree a decided kink or bend near the tip. In other cases the tail is of the short curling type of that of a bulldog; sometimes it starts quite straight, but divides in a fork-like manner near the tip; and in yet other instances it is altogether wanting, as in the typical Manx cats. These kink-tailed or tailless cats are moreover smaller in size than the ordinary short-tailed breeds, with rather longer hair, whose texture approaches that of rabbit-fur, and a cry said to be like that of the jungle-cat (F. chaus) of India and Africa, and more dog-like habits. Unless the jungle-cat, which is a nearly whole-coloured species, can claim the position, the ancestry of these Manx-Malay cats is still unknown. Kink-tailed cats, it should be added, are also known from Madagascar.

Among the domesticated cats of India a spotted type of colouring, with a more or less decided tendency for the spots to coalesce into stripes, is very noticeable; and it is probable that these cats are derived from the spotted Indian desert-cat (F. ornata), with a certain amount of crossing from other species. The so-called F. torquata of India is probably based on cats of this type which have reverted to the wild state. Other Indian cats with a tawny or fulvous type of colouring are probably the more or less modified descendants of the jungle-cat. From the same stock may be derived the Abyssinian breed, in which the ears are relatively large and occasionally tipped with long hairs (thus recalling the tufted ears of the jungle-cat). The colour is typically reddish-brown, each individual hair being “ticked” like that of a wild rabbit, whence the popular name of “bunny cat.” Another African breed is the Mombasa cat, in which the hair is reported to be unusually short and stiff.

By far the most remarkable of all the Old World domesticated breeds is, however, the royal Siamese cat, which almost certainly has an origin quite distinct from that of the ordinary European breeds; this being rendered evident not only by the peculiar type of colouring, but likewise by the cry, which is quite unmistakable. Siamese cats may have the tail either straight or kinked, but whether the latter feature belongs of right to the breed, or has been acquired by crossing with the ordinary black and tabby kink-tailed cats of the country, is not known. In the royal Siamese breed the head is rather long and pointed, the body also elongated with relatively slender limbs, the coat glossy and close, the eyes blue, and the general colour some shade of cream or pink, with the face, ears, feet, under-parts, and tail chocolate or seal-brown. There is however a wholly chocolate-coloured strain in which the eyes are yellow. The most remarkable feature about the breed is that the young are white. “The kittens,” observes a lady writer, “are born absolutely white, and in about a week a faint pencilling comes round the ears, and gradually all the points come. At four or five months they are lovely, as generally they retain their baby whiteness, which contrasts well with their almost black ears, deep-brown markings, and blue eyes.” In constitution these cats are extremely delicate. The blue eyes and the white coat of the kitten indicate that the Siamese breed is a semi-albino, which when adult tends towards melanism, such a combination of characters being apparently unknown in any other animal. If the frequent presence of a kink in the tail be an inherent feature, the breed is evidently related to the other kink-tailed Malay cats which, as already stated, have a cry differing from that of European cats. Should this be so, then if the ordinary Malay cats are the descendants of the jungle-cat, we shall have to assign the same ancestry to the Siamese breed.

Although definite information on this point is required, it seems probable that the southern part of North America and South America possessed certain native domesticated breeds of cats previous to the European conquest of the country; and if this be so, it will be obvious that these breeds must be derived from indigenous wild species. One of these breeds is the Paraguay cat, which when adult weighs only about three pounds, and is not more than a quarter the size of an ordinary cat. The body is elongated, and the hair, especially on the tail, short, shiny and close. This small size and elongated form suggest origin from the jaguarondi (F. jaguarondi), a chestnut-coloured wild species; but information appears to be lacking with regard to the colouring of the domesticated breed. Another South American breed is said to be free from the hideous “caterwauling” of the ordinary cat. In old days New Mexico was the home of a breed of hairless cats, said to have been kept by the ancient Aztecs, but now well-nigh if not completely extinct. Although entirely naked in summer, these cats developed in winter a slight growth of hair on the back and the ridge of the tail.

(R. L.*)

[1] The word “cat” is applied to various objects, in all cases an application of the name of the animal. In medieval siegecraft the “cat” (Med. Lat. chattus or gattus, chatta or gatta, in Fr. chat or chat-chasteil) was a movable pent-house used to protect besiegers when approaching a wall or gateway, for the purpose of sapping, mining or direct attack, or to cover a ram or other battering-engine. The word is also sometimes applied to a heavy timber fitted with iron spikes or projections to be thrown down upon besiegers, and to the large work known as a “cavalier.” “Cat” or “cat-head,” in nautical usage, is the projecting beam on the bows of a ship used to clear the anchor from the sides of the vessel when weighed. The stock of the anchor rests on the cat-head when hung outside the ship. The name is also used of a type of a vessel, now obsolete, and formerly used in the coal and timber trade on the north-east coast of England; it had a deep waist and narrow stem; it is still applied to a small rig of sailing boats, with a single mast stepped far forward, with a fore and aft sail. Among other objects also known by the name of “cat” is the small piece of wood pointed at either end used in the game of tip-cat, and the instrument of punishment, generally known as the “cat o’ nine tails.” This consists of a handle of wood or rope, about 18 in. long, with nine knotted cords or thongs. The multiplication of thongs for purposes of flogging is found in the old Roman flagellum, a scourge, which had sometimes three thongs with bone or bronze knots fastened to them. The “cat” was the regular instrument with which floggings were performed in the British army and navy. Since the abolition of flogging in the services, the use of the cat is now restricted to certain classes of offenders in military prisons (Army Act 1881, § 133). In the English criminal law, where corporal punishment is ordered by the court for certain criminal offences, the “cat” is used only where the prisoner is over sixteen years of age. It may not be used except when actually ordered in the sentence, and must be of a pattern approved by a secretary of state. Further floggings are inflicted with the “cat” upon convicted prisoners for breaches of discipline in prison. They must be ordered by the visitors of the prison and confirmed by the home secretary.

CATABOLISM, or Katabolism (Gr. κατἀ, down, βολή, a throw), the biological term for the reverse of anabolism, namely the breaking down of complex into simpler substances, destructive metabolism (see [Physiology]).

CATACLYSM (Gr. κατακλυσμός, a deluge), a great flood or deluge (q.v.). The term is used in geology to denote an overwhelming catastrophe which has produced sudden changes in the earth’s surface; and also, figuratively, of any great and violent change which sweeps away the existing social or political order.

CATACOMB, a subterranean excavation for the interment of the dead or burial-vault. In this sense the word “catacomb” has gained universal acceptance, and has found a place in most modern languages. The original term, catacumbae, however, had no connexion with sepulture, but was simply the name of a particular locality in the environs of Rome. It was derived from the Greek κατά and κύμβη, “a hollow,” and had reference to the natural configuration of the ground. In the district that bore this designation, lying close to the Appian Way, the basilica of San Sebastiano was erected, and the extensive burial-vaults beneath that church—in which, according to tradition, the bodies of the apostles St Peter and St Paul rested for a year and seven months previous to their removal to the basilicas which bear their names—were, in very early times, called from it coemeterium ad catacumbas, or catacumbas alone. From the celebrity of this cemetery as an object of pilgrimage its name became extensively known, and in entire forgetfulness of the origin of the word, catacumbae came to be regarded as a generic appellation for all burial-places of the same kind. This extension of the term to Christian burial-vaults generally dates from the 9th century, and obtained gradual currency through the Christian world. The original designation of these places of sepulture is crypta or coemeterium.

The largest number of Christian catacombs belong to the 3rd and the early part of the 4th centuries. The custom of subterranean interment gradually died out, and entirely ceased with the sack of Rome by Alaric, a.d. 410. “The end of the catacomb graves,” writes Mommsen (Cont. Rev., May 1871), “is intimately connected with the end of the powerful city itself.... Poverty took the place of wealth, ... the traditions of the Christian tomb-architects sank into utter insignificance, and the expanse of the wasted Campagna now offered room enough to bury the few bodies, without having to descend as once far down below the surface of the earth.” The earliest account of the catacombs, that of St Jerome narrating his visits to them when a schoolboy at Rome, about a.d. 354, shows that interment in them was even then rare if it had not been altogether discontinued; and the poet Prudentius’s description of the tomb of the Christian martyr Hippolytus, and the cemetery in which it stood, leads us to the same conclusion. With the latter part of the 4th century a new epoch in the history of the catacombs arose—that of religious reverence. In the time of Pope Damasus, a.d. 366-384, the catacombs had begun to be regarded with special devotion, and had become the resort of large bands of pilgrims, for whose guidance catalogues of the chief burial-places and the holy men buried in them were drawn up. Some of these lists are still extant.[1] Pope Damasus himself displayed great zeal in adapting the catacombs to their new purpose, restoring the works of art on the walls, and renewing the epitaphs over the graves of the martyrs. In this latter work he employed an engraver named Furius Philocalus, the exquisite beauty of whose characters enables the smallest fragment of his work to be recognized at a glance. This gave rise to extensive alterations in their construction and decoration, which has much lessened their value as authentic memorials of the religious art of the 2nd and 3rd centuries. Subsequent popes manifested equal ardour, with the same damaging results, in the repair and adornment of the catacombs, and many of the paintings covering their walls, which have been assigned to the period of their original construction, are really the work of these later times. The catacombs shared in the devastation of Rome by the Goths under Vitiges in the 6th century and by the Lombards at a later period; and partly through the spoliation of these barbarian invaders, partly through the neglect of those who should have been their guardians, they sank into such a state of decay and pollution that, as the only means of preserving the holy remains they enshrined from further desecration, Pope Paul I., in the latter part of the 8th century, and Pope Paschal, at the beginning of the 9th, entered upon the work of the translation of the relics, which was vigorously carried on by successive pontiffs until the crypts were almost entirely despoiled of their dead. The relics having been removed, the visits of pilgrims naturally ceased, and by degrees the very existence of those wonderful subterranean cemeteries was forgotten. Six centuries elapsed before the accidental discovery of a sepulchral chamber by some labourers digging for pozzolana earth (May 31, 1578) revealed to the amazed inhabitants of Rome “the existence,” to quote a contemporary record, “of other cities concealed beneath their own suburbs.” Baronius, the ecclesiastical historian, was one of the first to visit the new discovery, and his Annals in more than one place evidence his just appreciation of its importance. The true “Columbus of this subterranean world,” as he has been aptly designated, was the indefatigable Antonio Bosio (d. 1629), who devoted his life to the personal investigation of the catacombs, the results of which were given to the world in 1632 in a huge folio, entitled Roma sotterranea, profusely illustrated with rude but faithful plans and engravings. This was republished in a Latin translation with considerable alterations and omissions by Paolo Aringhi in 1651; and a century after its first appearance the plates were reproduced by Giovanni Bottari in 1737, and illustrated with great care and learning. Some additional discoveries were described by Marc Antonio Boldetti in his Osservazioni, published in 1720; but, writing in the interests of the Roman Church with an apologetic, not a scientific object, truth was made to bend to polemics, and little addition to our knowledge of the catacombs is to be gained from his otherwise important work. The French historian of art, Seroux d’Agincourt, 1825, by his copious illustrations, greatly facilitated the study of the architecture of the catacombs and the works of art contained in them. The works of Raoul Rochette display a comprehensive knowledge of the whole subject, extensive reading, and a thorough acquaintance with early Christian art so far as it could be gathered from books, but he was not an original investigator. The great pioneer in the path of independent research, which, with the intelligent use of documentary and historical evidence, has led to so vast an increase in our acquaintance with the Roman Catacombs, was Padre Marchi of the Society of Jesus. His work, Monumenti delle arti christiane primitive, is the first in which the strange misconception, received with unquestioning faith by earlier writers, that the catacombs were exhausted sand-pits adapted by the Christians to the purpose of interment, was dispelled, and the true history of their formation demonstrated. Marchi’s line of investigation was followed by the Commendatore De Rossi, and his brother Michele, the former of whom was Marchi’s fellow-labourer during the latter part of his explorations; and it is to them that we owe the most exhaustive scientific examination of the whole subject. The Catacombs of Rome are the most extensive with which we are acquainted, and, as might be expected in the centre of the Christian world, are in many respects the most remarkable. No others have been so thoroughly examined and illustrated. These may, therefore, be most appropriately selected for description as typical examples.

Our description of the Roman Catacombs cannot be more appropriately introduced than by St Jerome’s account of his visits to them in his youth, already referred to, which, after the lapse of above fifteen centuries, presents a Catacombs of Rome. most accurate picture of these wonderful subterranean labyrinths. “When I was a boy,” he writes, “receiving my education in Rome, I and my schoolfellows used, on Sundays, to make the circuit of the sepulchres of the apostles and martyrs. Many a time did we go down into the catacombs. These are excavated deep in the earth, and contain, on either hand as you enter, the bodies of the dead buried in the wall. It is all so dark there that the language of the prophet (Ps. lv. 15) seems to be fulfilled, ‘Let them go down quick into hell.’ Only occasionally is light let in to mitigate the horror of the gloom, and then not so much through a window as through a hole. You take each step with caution, as, surrounded by deep night, you recall the words of Virgil—

“Horror ubique animos, simul ipsa silentia terrent.”[2]

In complete agreement with Jerome’s vivid picture the visitor to the Roman Catacombs finds himself in a vast labyrinth of narrow galleries, usually from 3 to 4 ft. in width, interspersed with small chambers, all excavated at successive levels, in the strata of volcanic rock subjacent to the city and its environs, and constructed originally for the interment of the Christian dead. The galleries are not the way of access to the cemeteries, but are themselves the cemeteries, the dead being buried in long low horizontal recesses, excavated in the vertical walls of the passages, rising tier above tier like the berths in a ship, from a few inches above the floor to the springing of the arched ceiling, to the number of five, six or even sometimes twelve ranges. These galleries are not arranged on any definite plan, but, as will be seen from the plan (fig. 1), they intersect one another at different angles, producing an intricate network which it is almost impossible to reduce to any system. They generally run in straight lines, and as a rule preserve the same level. The different storeys of galleries lie one below the other (fig. 2) to the number of four or five (in one part of the cemetery of St Calixtus they reach seven storeys), and communicate with one another by stairs cut out of the living rock. Light and air are introduced by means of vertical shafts (luminaria) running up to the outer air, and often serving for several storeys. The drawing (fig. 3) from Northcote gives a very correct idea of these galleries, with the tiers of graves pierced in the walls. The doorways which are seen interrupting the lines of graves are those of the family sepulchral chambers, or cubicula, of which we shall speak more particularly hereafter.

The graves, or loculi, as they are commonly designated, were, in the Christian cemeteries, with only a few exceptions (Padre Marchi produces some from the cemetery of St Ciriaca, Monum. primitiv. tav. xiv. xliii. xliv.), parallel with the length of the gallery. In the pagan cemeteries, on the other hand, the sepulchral recess as a rule entered the rock like an oven at right angles to the corridor, the body being introduced endways. The plan adopted by the Christians saved labour, economized space, and consulted reverence in the deposition of the corpse. These loculi were usually constructed for a single body only. Some, however, were formed to contain two, three, or four, or even more corpses. Such recesses were known respectively as bisomi, trisomi, quadrisomi, &c., terms which often appear in the sepulchral inscriptions. After the introduction of the body the loculi were closed with the greatest care, either with slabs of marble the whole length of the aperture, or with huge tiles, three being generally employed, cemented together with great exactness so as to prevent the escape of the products of decomposition (fig. 4). Where any epitaph was set up—an immense number are destitute of any inscription at all—it is always painted or engraved on these slabs or tiles. In the earlier interments the epitaph is usually daubed on the slab in red or black paint. In later examples it is incised in the marbles, the letters being rendered clearer by being coloured with vermilion. The enclosing slab very often bears one or more Christian symbols, such as the dove, the anchor, the olive-branch, or the monogram of Christ (figs. 5, 6). The palm branch, which is also of frequent occurrence, is not an indisputable mark of the last resting-place of a martyr, being found in connexion with epitaphs of persons dying natural deaths, or those prepared by persons in their lifetime, as well as in those of little children, and even of pagans. Another frequent concomitant of these catacomb interments, a small glass vessel containing traces of the sediment of a red fluid, embedded in the cement of the loculus (fig. 7), has no better claim. The red matter proves to be the remains of wine, not of blood; and the conclusion of the ablest archaeologists is that the vessels were placed where they are found, after the eucharistic celebration or agape on the day of the funeral or its anniversary, and contained remains of the consecrated elements as a kind of religious charm. Not a few of the slabs, it is discovered, have done double duty, bearing a pagan inscription on one side and a Christian one on the other. These are known as opisthographs. The bodies were interred wrapped in linen cloths, or swathed in bands, and were frequently preserved by embalming. In the case of poorer interments the destruction of the body was, on the contrary, often accelerated by the use of quicklime.

Interment in the wall-recess or loculus, though infinitely the most common, was not the only mode employed in the catacombs. Other forms of very frequent recurrence are the table tomb and arched tomb, or arcosolium. From the annexed woodcuts it will be seen that these only differ in the form of the surmounting recess. In each case the arched tomb was formed by an oblong chest, either hollowed out of the rock, or built of masonry, and closed with a horizontal slab. But in the table-tomb (fig. 8) the recess above, essential for the introduction of the corpse, is square, while in the arcosolium (fig. 9), a form of later date, it is semicircular. Sarcophagi are also found in the catacombs, but are of rare occurrence. They chiefly occur in the earlier cemeteries, and the costliness of their construction confined their use to the wealthiest classes—e.g. in the cemetery of St Domitilla, herself a member of the imperial house. Another unfrequent mode of interment was in graves like those of modern times, dug in the floor of the galleries (Marchi, u.s., tav. xxi. xxvi.). Table-tombs and arcosolia are by no means rare in the corridors of the catacombs, but they belong more generally to the cubicula, or family vaults, of which we now proceed to speak.

These cubicula are small apartments, seldom more than 12 ft. square, usually rectangular, though sometimes circular or polygonal, opening out of the main corridors. They are not unfrequently ranged regularly along the sides of the galleries, the doors of entrance, as may be seen in a previous illustration (fig. 3), following one another in as orderly succession as the bedchamber doors in the passage of a modern house. The roof is sometimes flat, but is more usually vaulted, and sometimes rises into a cupola. Both the roof and the walls are almost universally coated with stucco and covered with fresco paintings—in the earlier works merely decorative, in the later always symbolical or historical. Each side of the cubiculum, except that of the entrance, usually contains a recessed tomb, either a table-tomb or an arcosolium. That facing the entrance was the place of greatest honour, where in many instances the remains of a martyr were deposited, whose tomb, according to primitive usage, served as an altar for the celebration of the eucharist. This was sometimes, as in the Papal crypt of St Calixtus (fig. 10), protected from irreverence by lattice work (transennae) of marble. The cubiculum was originally designed for the reception of a very limited number of dead. But the natural desire to be buried near one’s relatives caused new tombs to be cut in the walls, above and around and behind the original tombs, the walls being thus completely honeycombed with loculi, sometimes as many as seventy, utterly regardless of the paintings originally depicted on the walls. Another motive for multiplying the number of graves operated when the cubiculum contained the remains of any noted saint or martyr. The Christian antiquary has cause continually to lament the destruction of works of art due to this craving. One of the most perfect examples of early Christian pictorial decoration, the so-called “Dispute with the Doctors,” in the catacomb of Calixtus, the “antique style of beauty” of which is noticed by Kugler, has thus suffered irreparable mutilation, the whole of the lower part of the picture having been destroyed by the excavation of a fresh grave-recess (Bottari, vol. ii. tav. 15). The plates of De Rossi, Ferret, and, indeed, all illustrations of the catacombs, exhibit frequent examples of the same destructive superstition. The illustrations (figs. 11 and 12), taken from De Rossi’s great work, representing two of the cubicula in the cemetery of St Calixtus, show the general arrangement of the loculi and the character of the frescoes which ornament the walls and roof. These paintings, it will be seen, are simply decorative, of the same style as the wall-paintings of the baths, and those of Pompeii.

Each cubiculum was usually the burying-place of some one family, all the members of which were interred in it, just as in the chantry-chapels connected with medieval churches. In them was celebrated the funeral-feast on the day of burial and on its anniversary, as well as the eucharist, which was the invariable accompaniment of funerals in the primitive church (Bingham, Orig. Eccl. bk. xxiii. c. iii. 12). The funeral-banquet descended to the Christian church from pagan times, and was too often profaned by heathen licence. St Augustine, in several passages, inveighs against those who thus by “gluttony and insobriety buried themselves over the buried,” and “made themselves drunk in the chapels of the martyrs, placing their excesses to the score of religious reverence for the dead.” (August., De Mor. Eccl. Cathol., c. 34, Contr. Faust, lib. xx. c. 21, Confess., lib vi. c. 2) Some curious frescoes representing these funeral-feasts, found in the cubicula which were the scene of them, are reproduced by Bosio (pp. 355, 391) and others. A romantic air has been thrown over these burial chapels by the notion that they were the places of worship used by the Christians in times of persecution. This to a certain extent is doubtless true, as in the case of the chapel of Santa Priscilla, where the altar or stone coffin of a martyr remains, with a small platform behind it for the priest or bishop to stand upon. But that they can have been so used to any large extent is rendered impossible by their limited dimensions, as none of them could hold more than fifty or sixty persons. In some of the catacombs, however, there are larger halls and connected suites of chapels which may possibly have been constructed for the purpose of congregational worship during the dark periods when the public exercise of the Christian religion was made penal. The most remarkable of these is in the cemetery of Sant’ Agnese (see plan, fig. 13). It consists of five rectangular compartments, three on one side of the corridor and two on the other, connected by a passage intersecting the gallery at right angles. Two of the five compartments are supposed to have been assigned to male, and two to female worshippers, the fifth, at the extremity of the whole, being reserved for the altar and its ministers. In the centre of the end-wall stands a stone chair (fig. 14), considered to have been the episcopal cathedra, with a bench for the clergy on each side. There is no trace of an altar, which may, Marchi thinks, have been portable. The walls of the compartments are occupied by arched sepulchral recesses, above and below which are tiers of ordinary graves or loculi. The arrangements are certainly such as indicate a congregational purpose, but the extreme narrowness of the suite, and still more of the passage which connects the two divisions, must have rendered it difficult for any but a small number to take any intelligent part in the services at the same time. Although the idea of the use of the catacombs for religious worship may have been pressed too far, there can be no doubt that the sacred rites of the church were celebrated within them. We have already spoken of the eucharistic celebrations of which the cubicula were the scene; and still existing baptisteries prove that the other sacrament was also administered there. The most remarkable of these baptisteries is that in the catacomb of San Pontianus (fig. 15). Ten steps lead down to a basin of sufficient depth for immersion, supplied by a spring. Some of the subterranean chambers contain armed seats and benches cut out of the tufa rock. These are supposed by Marchi and others to indicate schoolrooms, where the catechumens were instructed by the bishop or presbyters. But this theory wants verification. It is impossible not to be struck with the remarkable analogy between these rock-hewn chairs and those discovered in the Etruscan tombs, of the purpose of which no satisfactory explanation has been given.

Very exaggerated statements have been made as to the employment of the catacombs as dwelling-places by the Christians in times of persecution. We have, however, sufficient evidence that they were used as places of refuge from Theories of the use of the catacombs. the fury of the heathen, in which the believers—especially the bishops and clergy, who would naturally be the first objects of attack—might secrete themselves until the storm had blown over. This was a purpose for which they were admirably adapted both by the intricacy of their labyrinthine passages, in which any one not possessing the clue would be inevitably lost, and the numerous small chambers and hiding-places at different levels which might be passed unperceived in the dark by the pursuers. As a rule also the catacombs had more than one entrance, and frequently communicated with an arenaria or sand-quarry; so that while one entrance was carefully watched, the pursued might escape in a totally different direction by another. But, to quote J.H. Parker, “the catacombs were never intended, nor fit for, dwelling-places, and the stories of persons living in them for months are probably fabulous. According to modern physicians it is impossible to live many days in the caves of pozzolana in which many of the catacombs are excavated.” Equally exaggerated are the statements as to the linear and lateral extent of the catacombs, and their intercommunication with one another. Without resorting to this exaggeration, Mommsen can speak with perfect truth of the “enormous space occupied by the burial vaults of Christian Rome, not surpassed even by the cloacae or sewers of Republican Rome,” but the data are too vague to warrant any attempt to define their dimensions. Marchi has estimated the united length of the galleries at from 800 to 900 m., and the number of interments at between 6,000,000 and 7,000,000; Martigny’s estimate is 587 m.; and Northcote’s, lower still, at “not less than 350 m.” The idea of general intercommunication is negatived by the fact that the chief cemeteries are separated by low ground or valleys, where any subterranean galleries would be at once filled with water.

It now remains to speak of the history of these subterranean burial-places, together with the reasons for, and mode of, their construction. From the period of the rediscovery of the catacombs in the 16th century till comparatively recent times a gigantic fallacy prevailed, repeated by writer after writer, identifying the Christian burial-places with disused sand-pits. It was accepted as an unquestionable fact by every one who undertook to describe the catacombs, that the Christians of Rome, finding in the labyrinthine mazes of the exhausted arenariae, which abounded in the environs of the city, whence the sand used in building had been extracted, a suitable place for the interment of their martyred brethren, where also the sacred rites accompanying the interment might be celebrated without fear of interruption, took possession of them and used them as cemeteries. It only needed a comparison of the theory with the visible facts to refute it at once, but nearly three centuries elapsed before the independence of the arenariae and the catacombs was established. The discovery of this independence is due to Marchi. Starting with the firmest belief in the old traditional view, his own researches by degrees opened his eyes to the truth, now universally recognized, that the catacombs were exclusively the work of the Christians, and were constructed for the interment of the dead. It is true that a catacomb is often connected with the earlier sand-quarry, and starts from it as a commencement, but the two are excavated in different strata, suitable to their respective purposes, and their plan and construction are so completely unlike as to render any confusion between them impossible.

The igneous formation of which the greater part of the Roman Campagna is, in its superior portion, composed, contains three strata known under the common name of tufa,—the “stony,” “granular,” and “sandy” tufa,—the last being commonly known as pozzolana.[3] The pozzolana is the material required for building purposes, for admixture with mortar; and the sandpits are naturally excavated in the stratum which supplies it. The stony tufa (tufa litoide) is quarried as building-stone. The granular tufa is useless for either purpose, containing too much earth to be employed in making mortar, and being far too soft to be used as stone for building. Yet it is in this stratum, and in this alone, that the catacombs are constructed; their engineers avoiding with equal care the solid stone of the tufa litoide and the friable pozzolana, and selecting the stratum of medium hardness, which enabled them to form the vertical walls of their galleries, and to excavate the loculi and cubicula without severe labour and also without fear of their falling in. The annexed illustration (fig. 16) from Marchi’s work, when compared with that of the catacomb of Sant’ Agnese already given, presents to the eye the contrast between the wide winding irregular passages of the sand-pit, calculated for the admission of a horse and cart, and the narrow rectilinear accurately-defined galleries of the catacomb. The distinction between the two is also plainly exhibited when for some local or private reasons an ancient arenaria has been transformed into a cemetery. The modifications required to strengthen the crumbling walls to support the roof and to facilitate the excavation of loculi, involved so much labour that, as a rule, after a few attempts, the idea of utilizing an old quarry for burial purposes was abandoned.

Another equally erroneous idea was that these vast burial-places of the early Christians remained entirely concealed from the eyes of their pagan neighbours, and were constructed not only without the permission of the municipal authorities but without their cognizance. Nothing can be farther from the truth. Such an idea is justly stigmatized by Mommsen as ridiculous, and reflecting a discredit as unfounded as it is unjust on the imperial police of the capital. That such vast excavations should have been made without attracting attention, and that such an immense number of corpses could have been carried to burial in perfect secrecy is utterly impossible. Nor was there any reason why secrecy should have been desired. The decent burial of the dead was a matter especially provided for by the Roman laws. No particular mode was prescribed. Interment was just as legal as cremation, and had, in fact, been universally practised by the Romans until the later days of the republic.[4] The bodies of the Scipios and Nasos were buried in still existing catacombs; and if the Christians preferred to adopt that which Minucius Felix calls “the better, and more ancient custom of inhumation” (Octavius, c. 2), there was absolutely nothing, to quote the words of Northcote (Roma sotterran. pp. 56, 61), “either in their social or religious position to interfere with their freedom of action. The law left them entire liberty,... and the faithful did but use their liberty in the way that suited them best, burying their dead according to a fashion to which many of them had been long accustomed, and which enabled them at the same time to follow in death the example of him who was also their model in life.” Interment in rock-hewn tombs, “as the manner of the Jews is to bury,” had been practised in Rome by the Jewish settlers for a considerable period anterior to the rise of the Christian Church. A Jewish catacomb, now lost, was discovered and described by Bosio (Rom. sott. p. 141), and others are still accessible. They are to be distinguished from Christian catacombs only by the character of their decorations, the absence of Christian symbols and the language of their inscriptions. There would, therefore, be nothing extraordinary in the fact that a community, always identified in the popular heathen mind with the Jewish faith, should adopt the mode of interment belonging to that religion. Nor have we the slightest trace of any official interference with Christian burials, such as would render secrecy necessary or desirable. Their funerals were as much under the protection of the law, which not only invested the tomb itself with a sacred character, but included in its protection the area in which it stood, and the cella memoriae or chapel connected with it, as those of their heathen fellow-citizens, while the same shield would be thrown over the burial-clubs, which, as we learn from Tertullian (Apolog. c. 39), were common among the early Christians, as over those existing among the heathen population of Rome.

We may then completely dismiss the notion of there being any studied secrecy in connexion with the early Christian cemeteries, and proceed to inquire into the mode of their formation. Almost without exception, they had their origin in Mode of formation. small burial areas, the property of private persons or of families, gradually ramifying and receiving additions of one subterranean storey after another as each was required for interments. The first step would be the acquisition of a plot of ground either by gift or purchase for the formation of a tomb, Christians were not beyond the pale of the law, and their faith presented no hindrance to the property being secured to them in perpetuity. To adapt the ground for its purpose as a cemetery, a gallery was run all round the area in the tufa rock at a convenient depth below the surface, reached by staircases at the corners. In the upright walls of these galleries loculi were cut as needed to receive the dead. When these first four galleries were full others were mined on the same level at right angles to them, thus gradually converting the whole area into a net-work of corridors. If a family vault was required, or a burial chapel for a martyr or person of distinction, a small square room was excavated by the side of the gallery and communicating with it. When the original area had been mined in this way as far as was consistent with stability, a second storey of galleries was begun at a lower level, reached by a new staircase. This was succeeded by a third, or a fourth, and sometimes even by a fifth. When adjacent burial areas belonged to members of the same Christian confraternity, or by gift or purchase fell into the same hands, communications were opened between the respective cemeteries, which thus spread laterally, and gradually acquired that enormous extent which, “even when their fabulous dimensions are reduced to their right measure, form an immense work.”[5] This could only be executed by a large and powerful Christian community unimpeded by legal enactments or police regulations, “a living witness of its immense development corresponding to the importance of the capital.” But although, as we have said, in ordinary times there was no necessity for secrecy, yet when the peace of the Church was broken by the fierce and often protracted persecutions of the heathen emperors, it became essential to adopt precautions to conceal the entrance to the cemeteries, which became the temporary hiding-places of the Christian fugitives, and to baffle the search of their pursuers. To these stormy periods we may safely assign the alterations which may be traced in the staircases, which are sometimes abruptly cut off, leaving a gap requiring a ladder, and the formation of secret passages communicating with the arenariae, and through them with the open country.

When the storms of persecution ceased and Christianity had become the imperial faith, the evil fruits of prosperity were not slow to appear. Cemetery interment became a regular trade in the hands of the fossores, or grave-diggers, who appear to have established a kind of property in the catacombs, and whose greed of gain led to that destruction of the religious paintings with which the walls were decorated, for the quarrying of fresh loculi, to which we have already alluded. Monumental epitaphs record the purchase of a grave from the fossores, in many cases during the lifetime of the individual, not unfrequently stating the price. A very curious fresco, found in the cemetery of Calixtus, preserved by the engravings of the earlier investigators (Bottari, tom. ii. p. 126, tav. 99), represents a “fossor” with his lamp in his hand and his pick over his shoulder, and his tools lying about him. Above is the inscription, “Diogenes Fossor in Pace depositus.”

It is unnecessary to enter on any detailed description of the frescoes which cover the walls and ceilings of the burial-chapels in the richest abundance. It must suffice to say that the earliest examples are only to be distinguished from the mural decorations employed by their pagan contemporaries (as seen at Pompeii and elsewhere) by the absence of all that was immoral or idolatrous, and that it was only very slowly and timidly that any distinctly Decoration. religious representations were introduced. These were at first purely symbolical, meaningless to any but a Christian eye, such as the Vine, the Good Shepherd, the Sheep, the Fisherman, the Fish, &c. Even the personages of ancient mythology were pressed into the service of early Christian art, and Orpheus, taming the wild beasts with his lyre, symbolized the peaceful sway of Christ; and Ulysses, deaf to the Siren’s song, represented the Believer triumphing over the allurements of sensual pleasure. The person of Christ appeared but rarely, and then commonly simply as the chief personage in an historical picture. The events depicted from the life of Christ are but few, and always conform rigidly to the same traditional type. The most frequent are the miracle at Cana, the multiplication of the loaves and fishes, the paralytic carrying his bed, the healing of the woman with the issue of blood, the raising of Lazarus, Zacchaeus, and the triumphal entry into Jerusalem. The Crucifixion, and subjects from the Passion, are never represented. The cycle of Old Testament subjects is equally limited. The most common are the history of Jonah as a type of the Resurrection, the Fall, Noah receiving the dove with the olive branch, Abraham’s sacrifice of Isaac, Moses taking off his shoes, David with the sling, Daniel in the lions’ den, and the Three Children in the fiery furnace. The mode of representation is always conventional, the treatment of the subject no less than its choice being dictated by an authority to which the artist was compelled to bow. All the more valuable of these paintings have been produced in J.H. Parker’s series of photographs taken in the catacombs by the magnesium light.[6] Wilpert’s great work, in which these frescoes are reproduced in colours, now enables the student even better to distinguish the styles of different centuries and follow the course of artistic development or decay.

Beyond Rome and its suburbs the most remarkable Christian catacombs are those in the vicinity of Naples, described by Pelliccia (De Christ. Eccl. Polit. vol. iv. Dissert. 5), and in separate treatises by Bellerman and Schultze. Plans of them are also given by Agincourt in his great work on Christian art. These catacombs differ materially from those of Rome. They were certainly originally stone-quarries, and the hardness of the rock Catacombs of Naples. has made the construction practicable of wide, lofty corridors and spacious halls, very unlike the narrow galleries and contracted chambers in the Roman cemeteries. The mode of interment, however, is the same as that practised in Rome, and the loculi and arcosolia differ by little in the two. The walls and ceilings are covered with fresco paintings of different dates, in some cases lying one over the other. This catacomb contains an unquestionable example of a church, divided into a nave and chancel, with a rude stone altar and bishop’s seat behind it.

At Syracuse also there are very extensive catacombs known as “the Grottos of St John.” They are also figured by Agincourt, and described by Denon (Voyage en Sicile et Malte) and Führer. There is an entire underground city with Syracuse. several storeys of larger and smaller streets, squares and cross ways, cut out of the rock; at the intersection of the cross ways are immense circular halls of a bottle shape, like a glass-house furnace, lighted by air shafts. The galleries are generally very narrow, furnished on each side with arched tombs, and communicating with family sepulchral-chambers closed originally by locked doors, the marks of the hinges and staples being still visible. The walls are in many places coated with stucco adorned with frescoes, including palms, doves, labara and other Christian symbols. The ground-plans (figs. 19, 20), from Agincourt, of the catacomb and of one of the circular halls, show how widely this cemetery differs in arrangement from the Roman catacombs. The frequency of blind passages and of circular chambers will be noticed, as well as the very large number of bodies in the cruciform recesses, apparently amounting in one instance to nineteen. Agincourt remarks that this cemetery “gives an idea of a work executed with design and leisure, and with means very different from those at command in producing the catacombs of Rome.”

Denon also describes catacombs at Malta near the ancient capital of the island. The passages were all cut in a close-grained stone, and are very narrow, with arched ceilings, running very irregularly, and ramifying in all directions. Malta. The greater part of the tombs stand on either side of the galleries in square recesses (like the table-tombs of the Roman catacombs), and are rudely fashioned to imitate sarcophagi. The interments are not nearly so numerous as in other catacombs, nor are there any vestiges of painting, sculpture or inscriptions. At Taormina in Sicily is a Saracenic catacomb, also Taormina. figured by Agincourt. The main corridor is 12 ft. wide, having three or more ranges of loculi on either side, running longitudinally into the rock, each originally closed by a stone bearing an inscription.

Passing to Egypt, a small Christian catacomb at Alexandria is described and figured by de Rossi.[7] The loculi here also are set endways to the passage. The walls are abundantly decorated with paintings, one of a liturgical character. But the most extensive Egypt. catacombs at Alexandria are those of Egypto-Greek origin, from the largest of which, according to Strabo (lib. xvii. p. 795), the quarter where it is placed had the name of the Necropolis. The plan, it will be seen, is remarkable for its regularity (figs. 21, 22). Here, too, the graves run endways into the rock. Other catacombs in the vicinity of the same city are described by Pocock and other travellers, and are figured by Agincourt.

Subterranean cemeteries of the general character of those described are very frequent in all southern and eastern countries. A vast necropolis in the Sidon. environs of Saida, the ancient Sidon, is described in Renan’s Mission en Phénicie, and figured in Thobois’s plates. It consists of a series of apartments approached by staircases, the sides pierced with sepulchral recesses running lengthwise into the rock.

The rock-hewn tombs of Etruria scarcely come under the category of catacombs, in the usual sense, being rather independent family burial-places, grouped together in a necropolis. They are, however, far too remarkable Rocktombs of Etruria. to be altogether passed over. These sepulchres are usually hollowed out of the face of low cliffs on the side of a hill. They often rise tier above tier, and are sometimes all on the same level “facing each other as in streets, and branching off laterally into smaller lanes or alleys”; and occasionally forming “a spacious square or piazza surrounded by tombs instead of houses” (Dennis, Cities and Cemeteries of Etruria, ii. 31). The construction of the tombs commonly keeps up the same analogy between the cities of the living and those of the dead. Their plan is for the most part that of a house, with a door of entrance and passage leading into a central chamber or atrium, with others of smaller size opening from it, each having a stone-hewn bench or triclinium on three of its sides, on which the dead, frequently a pair of corpses side by side, were laid as if at a banquet. These benches are often hewn in the form of couches with pillows at one end, and the legs carved in relief. The ceilings have the representation of beams and rafters cut in the rock. In some instances arm-chairs, carved out of the living rock, stand between the doors of the chambers, and the walls above are decorated with the semblance of suspended shields. The walls are often covered with paintings in a very simple archaic style, in red and black. As a typical example of the Etruscan tombs we give the plan and section (figs. 23, 24) of the Grotta detta Sedia at Cervetri from Dennis (pp. 32, 35). The tombs in some instances form subterranean groups more analogous to the general idea of a catacomb. Of this nature is the very remarkable cemetery at Poggio Gaiella, near Chiusi, the ancient Clusium, of a portion of the principal storey of which the woodcut (fig. 25) is a plan. The most remarkable of these sepulchral chambers is a large circular hall about 25 ft. in diameter, supported by a huge cylindrical pillar hewn from the rock. Opening out of this and the other chambers, and connecting them together, are a series of low winding passages or cuniculi, just large enough for a man to creep through on all fours. No plausible suggestion has been offered as to the purpose of these mysterious burrows, which cannot fail to remind us of the labyrinth which, according to Varro’s description as quoted by Pliny (Hist. Nat. lib. xxxvi. c. 19, § 4), was the distinguishing mark of Porsena’s tomb, and which have led some adventurous archaeologists to identify this sepulchre with that of the great king of Etruria (Dennis, u.s., pp. 393 ff.).

Modern Discoveries.—In 1873 was discovered, near the cemetery of St Domitilla, the semi-subterranean basilica of Santi Nereo ed Achilleo, 100 ft. by 60 ft. This is now covered with a roof, and the fallen columns have been raised up. The lower part of a pillar, which once supported a baldachino over the altar, still preserves the name Acilleus, and beneath it a bas-relief of the martyr, with his hands bound, receiving his death-blow from the executioner. The base of a similar column has only feet in the same attitude, and probably bore the name Nereus. In a grave in the apse was found a large fragment of an inscription, composed by Pope Damasus, but set up by his successor Siricius, which, from the note-book of a Salzburg pilgrim of the 8th century, can be completed thus:—

Militiae nomen dederant saevum Officium pariter spectantes juss Praeceptis pulsante metu servi Mira fides rerum subito posue Conversi fugiunt ducis impia castr Projiciunt clypeos faleras tel Confessi gaudent Christi portar Credite per Damasum possit quid

Nereus (see Rom. xvi. 15) and Achilleus, said to have been baptized by St Peter, refused to do the bidding of Domitian as praetorians, and entering the service of Flavia Domitilla, suffered martyrdom with their mistress Petronilla, of the Aurelian family closely connected with the Flavii, and the spiritual daughter of St Peter, who was buried in a sarcophagus with the inscription:—

avreliae · petronillae · fil · dvlcissimae

This is now in St Peter’s, but was probably originally behind the apse of this basilica, for there is a fresco of her in an arcosolium, with a matron named Veneranda. The original entrance to the cemetery leads directly into a spacious corridor with no loculi, but recesses for sarcophagi, and decorations of the classical style of the 2nd century. From this a wide staircase leads directly down to a chamber, discovered in March 1881, of a very early date. Within an arcosolium is a tablet set up by “Aurelius Ampliatus and his son Gordian, to Aurelia Bonifatia, his incomparable wife, a woman of true chastity, who lived 25 years, 2 months, 4 days, and 2 hours.” The letters are of the 2nd century; but above the arcosolium was found a stone with great letters, 5 or 6 in. high: “AMPLIATI, the tomb of Ampliatus.” Now Ampliatus is a servile name: how comes it to be set up with such distinction in the sepulchre of the Flavii? Romans xvi. 8 supplies the answer: “Salute Ampliatus, most beloved to me in the Lord.” De Rossi thinks the identification well grounded (Bullettino, 1881, p. 74). Epitaphs of members of the Flavian family have been found here, and others stating that they are put up “Ex indulgentia flaviae domitillae vespasiani neptis.” So that De Rossi did not hesitate to complete an inscription on a broken stone thus:—

De Rossi began his excavations in the cemetery of Santa Priscilla in 1851, but for thirty years nothing but what had been described by Bosio came to light. In 1880 he unearthed a portion near the Cappella Greca, and found galleries that had not been touched since they were filled in during the Diocletian persecution. The loculi were intact and the epitaphs still in their places, so that “they form a kind of museum, in which the development, the formulae, and the symbolic figures of Christian epigraphy, from its origin to the end of the 3rd or 4th century, can be notified and contemplated, not in artificial specimens as in the Lateran, but in the genuine and living reality of their original condition.” (Bullett., 1884, p. 68). Many of the names mentioned in St Paul’s Epistles are found here: Phoebe, Prisca, Aquilius, Felix Ampliatus, Epenetus, Olympias, Onesimus, Philemon, Asyncritus, Lucius, Julia, Caius, Timotheus, Tychicus, Crescens, Urbanus, Hermogenes, Tryphaena and Trypho(sa) on the same stone. Petrus, a very rare name in the catacombs, is found here several times, both in Greek and in Latin. The neighbouring Coemeterium Ostrianum was anciently known as “Fons S. Petri,” “ubi Petrus baptizavit,” “ubi Petrus prius sedit.” This cemetery derives its name from Priscilla, mother of Pudens, who is said to have given hospitality to St Peter the Apostle. We are reminded of St Paul, and of his friends Aquila and Prisca, by a monument erected by an imperial freedman who was Praepositvs Tabernacvlorvm—chief tentmaker. In 1888 a corridor was discovered which had at one time been isolated from the rest of the cemetery. It had no loculi, but recesses in the wall to receive sarcophagi. At the end of the corridor there was a large chamber, 23 ft. by 13 ft., once lined with marble and the ceiling covered with mosaic, a few fragments of which still remain. The only tomb here was a sarcophagus, of which the broken front bears the letters which show it to have been the epitaph of one of the Acilian family:—

acilio glabrioni filio

In the vicinity are fragments of the epitaphs of Manius Acilius and Priscilla, of Quintus Acilius and Caia Acilia in Greek, another Greek inscription “Acilius Rufinus mayest thou live in God.” After careful examination of the nine Acilii, who were consuls, De Rossi concludes that this was the resting-place of that Acilius Glabrio, consul with Trajan, a.d. 91, who in the year of his consulate was compelled by Domitian to fight with beasts in the arena, and then banished and put to death in 95. The question of his Christianity seems settled by the discovery of the sepulchre of these Christian Acilii. From this crypt a staircase led up to the basilica in which Pope Silvester was buried, and the whole plan of which was laid bare by De Rossi. The tomb of St Silvester could be identified, and that of Pope Siricius “at his feet,” as the pilgrim noted (Bullett., 1890, pp. 106-119).

Just before De Rossi’s death, Mgr. Wilpert discovered in the Cappella Greca a painting of the “Fractio Panis” or eucharistic feast, which he cleansed from the dust with which it had been covered. The picture of the Blessed Virgin and Child, which De Rossi ascribed to the 2nd, if not to the 1st century, has received an unexpected proof of its antiquity. In 1890 the floor of the gallery in which it stands was excavated, and another floor was found to be 6 ft. below its supposed level. The loculi in this lower portion were intact, with inscriptions of the 2nd century still in their places, proving that the niche in which that picture was painted must have been considerably older than the lowering of the floor. A flight of iron steps enables the visitor now to examine this venerable specimen of early Christian art.

After the death of De Rossi, one of his pupils, H. Stevenson, since dead, discovered in 1896 a small subterranean basilica in the catacomb of Santi Pietro e Marcellino on the Via Labicana, with pious acclamations on the plaster similar to those in the Papal crypt in St Calixtus. Near the well-known subterranean chapel in the Coemeterium Ostrianum was discovered by Mgr. Crostarosa, in 1877, another chapel, in which Signor Armellini found traces of St Emerentiana, foster-sister of St Agnes. Near this a whole region of galleries has been brought to light with loculi intact.

Explorations conducted in the cemetery of Domitilla in 1897-1898 brought to light a fine double crypt with frescoes representing Christ seated between six male and female saints; also an inscription relating to a new saint (Eulalius) in a cubiculum of the 3rd century. In 1899-1900 were discovered two opposite cubicula in the catacomb of Santi Pietro e Marcellino. These were unknown to Bosio, and are both covered with frescoes, the vault being in one case decorated with the scene which represents Christ seated among the apostles and pronouncing sentence upon the defunct. An inscription discovered in 1900 on the site of the ancient cemetery of St Ciriaca, and dating from a.d. 405, states that one Euryalus bought a site ad mensam beati martyris Laurentii from a certain fossor whose name has been erased. This is interesting as an example of what was known as memoriae damnatio or the blotting out of a name on account of some dishonourable action. From the end of the 4th to the first half of the 5th century, the fossores had the privilege of selling sites, which frequently led to grave abuses. In 1901-1902 excavations in the cemetery of Santa Priscilla, near the Cappella Greca, revealed a polygonal chamber. This may have originally been the nymphaeum of the great villa of the Acilii Glabriones, the hypogaeum of which was discovered by De Rossi near this spot in 1888. It may have been used as a burial-place for martyrs, and Professor Marucchi is inclined to see in it the sepulchral chapel of Pope Marcellinus, who died in a.d. 304 during the persecutions of Diocletian. In 1902, in that part of the Via Ardeatina which passes between the cemeteries of Calixtus and Domitilla, was discovered a crypt with frescoes and the sanctuary of a martyr: it is thought that this, rather than a neighbouring crypt brought to light in 1897, may prove to be the sepulchral crypt of SS. Marcus and Marcellianus. In a cubiculum leading out of a gallery in the vicinity there was also discovered an interesting impression in plaster of an inscription of the mother of Pope Damasus, beginning:

hic damasi mater posvit lavren[tia membra].

In the same year building operations in the Via di Sant’ Onofrio revealed the presence of catacombs beneath the foundations: examination of the loculi showed that no martyrs or illustrious persons were buried here.

In 1903 a new cemetery with frescoes came to light on the Via Latina, considered by Marucchi to have belonged to a heretical sect. In the same year the Jewish cemetery on the Via Portuense, known to Bosio but since forgotten, was rediscovered. The subterranean basilica of SS. Felix and Adauctus, discovered by Boldetti and afterwards choked up with ruins, was cleared again: the crypt, begun by Damasus and enlarged by Siricius, contains frescoes of the 6th-7th centuries.

A good plan of the catacombs at Albano (at the 15th milestone of the Appian way), discovered by Boldetti and described by De Rossi, has been published by Marucchi (Nuovo Bulletino di archeologia cristiana, 1902, pp. 89 ff.). In 1904 a small subterranean cemetery was discovered at Anagnia. Catacombs have also been recently discovered on the site of Hadrumetum near Sousse in Tunisia.

Authorities.—The classical work on the catacombs of Rome is G.B. De Rossi’s Roma sotterranea, on which most of the accounts in other languages than Italian have been based. The fine volume by Mgr. Wilpert, Le Pitture delle catacombe romane (Rome, 1903), in which all the important frescoes are reproduced in colours, is to be regarded as an addition to the Roma sotterranea. All new discoveries made by the active Commissione di archeologia sacra are chronicled with as little delay as possible in the Nuovo Bulletino de archeologia cristiana published in Rome.

The most recent accounts of the catacombs are to be found in the following books:—Armellini, Gli Antichi Cimiteri cristiani di Roma e d’ Italia (Rome, 1893); O. Marucchi, Le Catacombe romane (Rome, 1903; also translated into French), Manuale di epigrafia cristiana (Milan, 1904); M. Besnier, Les Catacombes de Rome (Paris, 1909).

[1] The most important of these lists are the two Itineraries belonging to the first half of the 7th century, in the Salzburg library. One still earlier, but less complete, appears in the Notitia Urbis Romae, under the title Index Coemeteriorum. Another Itinerary, preserved at Einsiedeln, printed by Mabillon, dates from the latter half of the same century. That found in the works of William of Malmesbury (Hardy’s ed. vol. ii. pp. 539-544) appears to be copied from it, or both may be from the same source. De Rossi gives a comparative table of these Itineraries and other similar lists.

CATAFALQUE (a word of unknown origin, occurring in various forms in many European languages, meaning a funeral scaffold or temporary stage), a movable structure of wood sometimes richly decorated, erected temporarily at funeral ceremonies in a church to receive the coffin or effigy of the deceased; also an open hearse or funeral car.

CATALANI, ANGELICA (1780-1849), Italian opera-singer, daughter of a tradesman at Sinigaglia, was educated at the convent of Santa Lucia at Gubbio, where her magnificent soprano voice, of extraordinary compass and purity, soon became famous. In 1795 she made her début on the stage at Venice, and from that moment every impresario in Europe was anxious to engage her. For nearly thirty years she sang at all the great houses, receiving very large fees; her first appearance in London being at the King’s theatre in 1806. She remained in England, a prima donna without a serious rival, for seven years. Then she was given the management of the opera in Paris, but this resulted in financial failure, owing to the incapacity and extravagance of her husband, Captain Valabrègue, whom she married in 1806. But her continental tours continued to be enormously successful, until she retired in 1828. She settled at Florence in 1830, where she founded a free singing school for girls; and her charity and kindness were unbounded. She died of cholera in Paris on the 12th of June 1849.

CATALEPSY (from Gr. κατάληψις, a seizure), a term applied to a nervous affection characterized by the sudden suspension of sensation and volition, accompanied with a peculiar rigidity of the whole or of certain muscles of the body. The subjects of catalepsy are in most instances females of highly nervous temperament. The exciting cause of an attack is usually mental emotion operating either suddenly, as in the case of a fright, or more gradually in the way of prolonged depression. The symptoms presented vary in different cases, and even in the same individual in different attacks. Sometimes the typical features of the disease are exhibited in a state of complete insensibility, together with a statue-like appearance of the body which will retain any attitude it may be made to assume during the continuance of the attack. In this condition the whole organic and vital functions appear to be reduced to the lowest possible limit consistent with life, and to such a degree as to simulate actual death. At other times considerable mental excitement will accompany the cataleptic symptoms, and the patient will sing or utter passionate exclamations during the fit, being all the while quite unconscious. The attack may be of short duration, passing off within a few minutes. It may, however, last for many hours, and in some rare instances persist for several days; and it is conceivable that in such cases the appearances presented might be mistaken for real death, as is alleged to have occasionally happened. Catalepsy belongs to the class of functional nervous disorders (see [Muscle and Nerve]: Pathology) in which morbid physical and psychical conditions are mixed up. Although it is said to occur in persons in perfect health, careful inquiry will usually reveal some departure from the normal state, as is shown by the greater number of the recorded cases. More particularly is this true of females, in whom some form of menstrual derangement is generally found to have preceded the cataleptic affection. Catalepsy is sometimes associated with epilepsy and with grave forms of mental disease. In ordinary cases, however, the mental phenomena bear close resemblance to those witnessed in hysteria. In many of the subjects of catalepsy there appears to be a remarkable weakness of the will, whereby the tendency to lapse into the cataleptic state is not resisted but rather in some measure encouraged, and attacks may thus be induced by the most trivial circumstances.

CATALOGUE (a Fr. adaptation of the Gr. κατάλογος, a register, from καταλέγειν, to enrol or pick out), a list or enumeration, generally in alphabetical order, of persons, things, &c., and particularly of the contents of a museum or library. A catalogue raisonnée is such a list classified according to subjects or on some other basis, with short explanations and notes. (See also articles [Bibliography and Bibliology], and [Libraries].)

CATALONIA (Cataluña), a captaincy-general, and formerly a province of Spain, formerly also a principality of the crown of Aragon; bounded on the N. by the Pyrenees, W. by Aragon, S. by Valencia, and E. by the Mediterranean Sea. Pop. (1900) 1,966,382; area, 12,427 sq. m. The triangular territory of Catalonia forms the north-eastern corner of the Iberian Peninsula. A full account of the physical features, and of the modern development of commerce, communications, &c., in this area is given in the articles on the four provinces Barcelona, Gerona, Lérida and Tarragona, into which Catalonia was divided in 1833.

The coast, which is partly sandy, partly rocky, extends about 240 m.; its chief harbours are those of the capital, Barcelona, of Mataró, of Rosas and of Tarragona. The surface is much broken by spurs of the Pyrenees, the direction of which is generally south. Running south-west to north-east, and united on the north with one of the offsets of the Pyrenees, is the range of the Sierra Llena, which bisects Catalonia, and forms its central watershed. The principal rivers are the Ter, the Llobrégat, and the Ebro (q.v.), which all run into the Mediterranean. None of them is navigable. The climate, in spite of frequent mists and rains, sudden changes of temperature, and occasional great mid-day heat, is healthy and favourable to vegetation. The dwarf-palm, orange, lime, and olive grow in the warmer tracts; and on the higher grounds the thorn-apple, pomegranate, myrtle, esparto and heaths flourish. There is much woodland, but meadows and pastures are rare. Maize, millet, rye, flax, liquorice and fruits of all sorts—especially nuts, almonds, oranges, figs, walnuts and chestnuts—are produced. Wheat sufficient for one-fourth of the population is grown, and the vine is extensively cultivated. Few cattle, but numbers of sheep, goats and swine are reared. Game is plentiful, and the fisheries on the coast are excellent. The wines are for the most part rough and strong, though some are very good, especially when matured. They are much used to adulterate those of Oporto, or, after undergoing the blending operation termed compage, are passed off as Bordeaux wines in France. The best of them, priorato, is chiefly known in England, under the disguise of second or third-rate port; it was much used in the military hospitals of America during the Civil War.

The Catalonians are a frugal, sharp-witted, and industrious people, having much national pride, and a strong revolutionary spirit. They are distinct in origin from the other inhabitants of Spain, from whom they differ in their dialect and costume. In their great energy and their love of enterprise they resemble the Basques. Irrigation, careful husbandry and railroad communications have much developed the resources of their country, in themselves excellent; and there are many manufacturing towns and industrial establishments.

Catalonia was one of the first of the Roman possessions in Spain, and formed the north-eastern portion of Hispania Tarraconensis. About 470 it was occupied by the Alans and Goths. It was conquered by the Moors in 712, but these invaders were in turn dispossessed by the Spaniards and the troops of Charlemagne in 788. Catalonia was subsequently ruled by French counts, who soon, however, made themselves independent of France. By the marriage of Count Raymond Berenger IV. of Barcelona with Petronilla of Aragon, Catalonia became annexed to Aragon; but this union was frequently severed. In 1640, when Philip IV. attempted to deprive Catalonia of its rights and privileges, it gave itself up to Louis XIII. of France. It was restored to Spain in 1659, and was once more occupied by the French from 1694 to 1697. Under Philip V. Catalonia, in 1714, was deprived of its cortes and liberties. From 1808 to 1813 it was held by France. It was the scene of civil war in 1823, and of important revolutionary operations in the Carlist wars.

The history and literature of Catalonia have been closely studied, and in many cases the results of research are published in the Catalan language. See Cataluña, sus monumentos y artes, su naturaleza e historia (2 vols. of the illustrated series España), by P. Pifferrer, F. Pi Margall, and A.A. Pijoan (Barcelona, 1884); Historia de Cataluña, by V. Balaguer (11 vols., Madrid, 1886, &c.); Historia de Cataluña, by A. Bori y Fontestá (Barcelona, 1898); Origines históricos de Cataluña, by J. Balari y Jovany (Barcelona, 1899); Coleccio dels monografias de Catalunya, by J. Reig y Vilardell (Barcelona, 1890); Historia del derecho en Catalonia, Mallorca y Valencia, by B. Oliver (Madrid, 1876-1880); and Antigua marina catalana, by F. de Bofarull y Sans (Barcelona, 1898). The Revista catalana (Catalan Review), published at Barcelona from 1889, contains many valuable papers on local affairs. See also [Spain]: sections Language, Literature and History, and [Barcelona].

CATALPA, in botany, a genus belonging to the family Bignoniaceae and containing about ten species in America and eastern Asia. The best known is Catalpa bignonioides, a native of the eastern United States which is often cultivated in parks and gardens. It is a stately tree with large heart-shaped pointed leaves and panicles of white bell-shaped flowers streaked with yellow and brown purple.

CATALYSIS (from the Gr. κατά, down, and λύειν, to loosen), in chemistry, the name given to chemical actions brought about by a substance, termed the “catalyst,” which is recovered unchanged after the action. The term was introduced by Berzelius, who first studied such reactions. It is convenient to divide catalytic actions into two groups:—(1) when the catalyst first combines with one of the reaction components to form a compound which immediately reacts with the other components, the catalyst being simultaneously liberated, and free to react with more of the undecomposed first component; and (2), when the catalyst apparently reacts by mere contact. The theory of catalysis is treated under [Chemical Action]; in this article mention will be made of some of the more interesting examples.

A familiar instance of a catalytic action is witnessed when a mixture of potassium chlorate and manganese dioxide is heated to 350°, oxygen being steadily liberated, and the manganese dioxide being unchanged at the end of the reaction. The action may be explained as follows:—part of the chlorate reacts with the manganese dioxide to form potassium permanganate, chlorine and oxygen, the chlorine subsequently reacting with the permanganate to produce manganese dioxide, potassium chloride and oxygen, thus

2KClO3 + 2MnO2 = 2KMnO4 + Cl2 + O2 = 2KCl + 2MnO2 + 3O2.

This explanation is supported by the facts that traces of chlorine are present in the gas, and the pink permanganate can be recognized when little dioxide is used. Other oxides bring about the same decomposition at temperatures below that at which the chlorate yields oxygen when heated alone; but since such substances as kaolin, platinum black and some other finely powdered compounds exercise the same effect, it follows that the explanation given above is not quite general. Another example is Deacon’s process for the manufacture of chlorine by passing hydrochloric acid gas mixed with air over heated bricks which had been previously impregnated with a copper sulphate solution. The nitrous gases employed in the ordinary chamber process of manufacturing sulphuric acid also act catalytically. Mention may be made of the part played by water vapour in conditioning many chemical reactions. Thus sodium will not react with dry chlorine or dry oxygen; carbon, sulphur and phosphorus will not burn in perfectly dry oxygen, neither does nitric oxide give red fumes of the peroxide. In organic chemistry many catalytic actions are met with. In the class of reaction known as “condensations,” it may be found that the course of the reaction is largely dependent upon the nature of some substance which acts catalytically. One of the most important is the Friedel and Craft’s reaction, in which an aromatic compound combines with an alkyl haloid in the presence of aluminium, zinc or ferric chloride. It seems in this, as in other cases, that additional compounds are first formed which subsequently react with the re-formation of the catalyst. The formation of benzoin from benzaldehyde in the presence of potassium cyanide is another example; this action has been investigated by G. Bredig and Stern (Zeit. Elektrochem., 1904, 10, p. 582).

The second class of catalytic actions, viz. those occasioned by the presence of a metal or some other substance which undergoes no change, is of especial interest, and has received much attention. The accelerating influence of a clean platinum plate on the rate of combination of hydrogen and oxygen was studied by Faraday. He found that with the pure gases the velocity of reaction increased until the mixture exploded. The presence of minute quantities of carbon monoxide, carbon disulphide, sulphuretted hydrogen and hydrochloric acid inhibited the action; in the case of the first two gases, there is no alteration of the platinum surface, since the plate brings about combination when removed to an atmosphere of pure hydrogen and oxygen; with the last two gases, however, the surface is altered, since the plate will not occasion the combination when placed in the pure gases. M. Bodenstein (Zeit. phys. Chem., 1904, 46, p. 725) showed that combination occurs with measurable velocity at ordinary temperatures in the presence of compact platinum. More energetic combination is observed if the metal be finely divided, as, for instance, by immersing asbestos fibres in a solution of platinum chloride and strongly heating. The “spongy” platinum so formed brings about the combination of ammonia and oxygen to form water and nitric acid, of nitric oxide and hydrogen to form ammonia (see German Patent, 1905, 157,287), and of sulphur dioxide and oxygen to form sulphur trioxide. The last reaction, which receives commercial application in the contact process of sulphuric acid manufacture, was studied by M. Bodenstein and W. Pohl (Zeit. Elektrochem., 1905, 11, p. 373), who found that the equilibrium followed the law of mass-action (see also F. W. Küster, Zeit. anorg. Chem., 1904, 42, p. 453, R. Lucas, Zeit. Elektrochem., 1905, 11, p. 457). Other metals, such as nickel, iron, &c., can also react as catalysts. The use of finely divided nickel (obtained by reducing the oxide in a current of pure hydrogen at a temperature of 350°) has been carefully studied by P. Sabatier and J.B. Senderens; a summary of their results is given in the Ann. Chim. Phys., 1905 (viii.) 4, pp. 319-488. Of special interest is the condensation of acetylene. If this gas mixed with hydrogen be passed over the reduced nickel in the cold, the temperature may rise to as high as 150°, the acetylene disappearing and becoming replaced by a substance like petroleum. If the nickel be maintained at 200°, and the gases circulated for twenty-eight hours, a product, condensible to a yellow liquid having a beautiful fluorescence and boiling at 45°, is obtained. This substance closely resembles ordinary Pennsylvanian petroleum. If acetylene be passed alone over nickel heated to 200°-300°, a mixture, boiling at 60°-70° and having a green colour by diffused and a red by transmitted light, was obtained. This substance closely resembles Caucasian petroleum. The decomposition of carbon monoxide according to the reaction 2CO ⇄ C + CO2 is purely catalytic in the presence of nickel and cobalt, and also in the presence of iron, so long as the amount of carbon dioxide present does not exceed a certain amount (R. Schenck and W. Heller, Ber., 1905, 38, pp. 2132, 2139). It is of interest that finely divided aluminium and magnesium decompose methane, ethane, and ethylene into carbon and hydrogen in the same way as nickel. Charcoal at 350° also reacts catalytically; for example, Senderens found that ethyl alcohol was decomposed by animal charcoal into methane, ethylene, hydrogen, carbon monoxide and a little carbon dioxide, and propyl alcohol gave propylene, ethane, carbon monoxide and hydrogen, while G. Lemoine obtained from ethyl alcohol and wood charcoal a mixture of acetaldehyde and hydrogen.

CATAMARAN (a Tamil word, from catta, to tie, and maram wood), a surf-boat or raft used by the natives of Madras and along the Coromandel Coast in India. It is usually made of three tree trunks lashed together, the centre trunk being the largest and longest, and having one end bent upward to form a kind of prow. Catamarans of a larger size are in use in the West Indies and South America. The name is also given to two boats lashed together. Apparently through an erroneous connexion with cat, the name has been applied to a noisy scolding woman.

CATAMARCA, an Andean province of the Argentine Republic, lying W. of Santiago del Estero and Tucuman and extending to the Chilean frontier, with Los Andes and Salta on the N., Cordoba on the S.E., and Rioja on the S. Pop. (1895) 90,161; (1904, estimate) 103,082; area, 47,531 sq. m. The surface of the province is extremely broken, the Andes forming its western boundary, and the Aconquija, Ancaste, Ambato, Gulampaja and other ranges traversing it from north to south. It is composed very largely of high plateaus with a general slope southward broken by a few fertile valleys. The greater part of the province is arid and barren, being sheltered from the moist, eastern winds by the high mountain barriers of Aconquija and Ancaste. The rivers are small, and some of them are lost in the barren, sandy wastes. Others, especially in the foothills of the high sierras, are utilized to irrigate the fertile valleys. The climate of some of the low, sheltered valleys is extremely hot and unhealthy, but on the open plateaus it is peculiarly dry and bracing and is probably beneficial in the treatment of pulmonary diseases. The mineral resources of the province include gold, silver, copper, lead, nickel, iron, coal and malachite, but of these only copper and silver are mined, and these chiefly in the Andalgalá district. Salt deposits also exist, but are worked only to a limited extent. Cereals, alfalfa and fruit are grown. Large numbers of cattle, fattened in the alfalfa fields of Pucará, Tinogasta and Copacabana, are driven into northern Chile across the San Francisco pass (13,124 ft. above sea level) and mules are bred for the Bolivian market. Wine of an excellent quality is produced and exported. Tanning leather is another industry of the province, some of the trees growing in the Catamarca forests being rich in tannin. Catamarca is traversed by the Northern Central railway between Cordoba and the city of Catamarca, its capital, which passes around the southern extremity of the Sierra de Ancaste and makes a long detour to Chumbicha, near the Rioja frontier. The more important towns, after Catamarca, the capital, are Andalgalá and Tinogasta with populations (estimated, 1904) of 5000 to 6000 each. Belen is the oldest Spanish settlement in the province and was founded in 1550, being called Barco at first. The population is largely mixed with Indian blood.

CATAMARCA (San Fernando de Catamarca), capital of the above province on the Rio del Valle de Catamarca, 230 m. (318 m. by rail) N.N.W. of Cordoba. Pop. (1895) 7397; (1905, estimate) 8000, with a large percentage of mestizos. Catamarca is connected by railways with Rioja and Patquia and with Cordoba. The city stands in a narrow, picturesque valley at the foot of the Sierra de Ambato, 1772 ft. above sea level. The valley is highly fertile, partially wooded, and produces fruit in abundance, wine and some cereals. In the city are flour mills and tanneries, and among its exports are leather, fruit, wine, flour, and a curious embroidery for which the women of Catamarca have long been famous. There is a fine church, 220 by 90 ft., and a national college occupies the old Merced convent. The alameda is one of the prettiest in the Argentine Republic, having a reservoir of two acres surrounded by shrubbery and walks. Catamarca was founded in 1685 by Fernando de Mendoza because the town of Chacra, the former provincial capital, a few miles north of Catamarca, had been found unhealthy and subject to inundations. Previous to the selection of Chacra as the provincial capital, the seat of government was at San Juan de Londres, founded in 1558 and named after the capital of England by order of Philip II. in honour of his marriage with Queen Mary. The arid surroundings of Londres led to its partial abandonment and it is now a mere village. Cholla, a suburb of Catamarca, is inhabited wholly by Calchaqui Indians, a remnant of the original inhabitants of this region.

CATANIA (Gr. Katane, Rom. Catina[1]), a city and episcopal see of Sicily, the chief town of the province of Catania, on the east coast, 59 m. by rail S. of Messina, and 151 m. by rail S.E. of Palermo (102 m. direct). Pop. (1881) 100,417; (1905) 157,722. The principal buildings are handsome, and the main streets, meeting in the Piazzo del Duomo, are fine. The cathedral of S. Agatha, containing the relics of the saint, retains its three original Norman apses (1091), but is otherwise a large baroque edifice. The monument of Don Ferrando d’Acunea, a Spanish viceroy of Sicily, is a fine early Renaissance work (1494). In the west portion of the town is the huge Benedictine abbey of S. Nicola (now suppressed), the buildings of which occupy an area of about 21 acres and contain the museum, a library, observatory, &c. The church, dating, like the rest of the buildings, from 1693-1735, is the largest in Sicily, and the organ, built in 1760 by Donato del Piano, with 72 stops and 2916 pipes, is very fine. The university, founded in 1444, has regained some of its former importance. To the south near the harbour is the massive Castell’ Ursino, erected in 1232 by Frederick II. Remains of several ancient buildings exist, belonging in the main to the Roman period. The theatre, covered by a stream of lava, and built partly of small rectangular blocks of the same material, though in the main of concrete, has been superimposed upon the Greek building, some foundations of which, in calcareous stone, of which the seats are also made, still exist. It is 106 yds. in diameter, and is estimated to have accommodated 7000 spectators. Close to it are the remains of the so-called Odeum, of similar plan to the theatre but without a stage, and to the north is the church of S. Maria Rotonda, originally a Roman domed structure, perhaps part of a bath. To the north, in the Piazza Stesicoro, is the amphitheatre, a considerable portion of which has been uncovered, including the two corridors which ran round the whole building and gave access to the seats, while a part of the arcades of the exterior has been excavated and left open; the pillars are made of blocks of lava, and the arches of brick. The external diameters of the amphitheatre are 410 and 348 ft., while the corresponding diameters of the arena are 233 and 167 ft. It is thus the third largest Roman amphitheatre known, being surpassed only by that at Verona and the Colosseum. Remains of many other Roman buildings also exist beneath the modern town, among the best preserved of which may be noted the public baths (Thermae Achilleae) under the cathedral, and those under the church of S. Maria dell’ Indirizzo. The number of baths is remarkable, and gives some idea of the luxury of the place in Roman times. Their excellent preservation is accounted for by their burial under the lava. The majority were excavated by Prince Ignazio Biscari (1719-1786), who formed an important private collection of antiquities. Of the ancient city walls no authenticated remains exist.

Catania has a considerable export trade in sulphur, pumice stone, asphalt, oranges and lemons, almonds, filberts, cereals, wine (the total production of wine in the province amounted to 28,600,000 gallons in 1905) and oil. The total value of exports in 1905 was £1,647,075, and of imports £1,326,055, the latter including notably coal, almost entirely from the United Kingdom, and wheat, from Russian ports. The harbour is a good one, and has been considerably enlarged since 1872; £128,000 was voted in 1905 towards the completion of the harbour works by the Italian government. Sulphide of carbon is produced here; and there are large dyeworks, and a factory for making bed-stuffing from seaweed.

The ancient Catina was founded in 729 b.c. by colonists from Naxos, perhaps on the site of an earlier Sicel settlement—the name is entirely un-Greek, and may be derived from κάτινον, which in the Sicel language, as catinum in Latin, meant a basin, and would thus be descriptive of the situation of the town. Charondas, a citizen of Catina, is famous as its lawgiver, but his date and his birthplace are alike uncertain; the fragments preserved of his laws show that they belong to a somewhat primitive period. The poet Stesichorus of Himera died here. Very little is heard of Catina in history until 476 b.c., when Hiero I. removed its inhabitants to Leontini, repeopled it with 5000 Syracusans and 5000 Peloponnesians, and changed its name to Aetna. In 461 b.c., however, with the help of Ducetius and the Syracusans, the former inhabitants recovered possession of their city and revived the old name. Catina was, however, an ally of Athens during the Syracusan expedition (415-413 b.c.), and served as the Athenian base of operations in the early part of the war. In 403 b.c. it was taken by Dionysius of Syracuse, who plundered the city, sold the inhabitants into slavery and replaced them with Campanian mercenaries. In the First Punic War it was one of the first cities of Sicily to be taken by the Romans (263 b.c.). Marcellus constructed a gymnasium here out of the booty of Syracuse. In 123 b.c. there was an eruption of Etna so violent that the tithe on the territory of Catina payable to Rome was remitted for ten years. It appears to have been a flourishing city in the ist century b.c., but to have suffered from the ravages of Sextus Pompeius. It became a Roman colonia under Augustus, and it is from this period that the fertile plain, hitherto called the plain of Leontini, begins to be called the plain of Catina. It seems to have been at this time the most important city in the island, to judge from the language of Strabo and the number of inscriptions found there. In a.d. 251 a lava stream threatened the town and entered the amphitheatre, which in the time of Theodoric had fallen into ruins, as is clear from the fact that he permitted the use of its fallen stones to build the city wall. It was recovered by Belisarius in 535, sacked by the Saracens in 902 and taken by the Normans. The latter founded the cathedral; but the town was almost entirely destroyed by earthquake in 1170, and devastated by Henry VI. in 1197. It became the usual residence of the Aragonese viceroys of the 13th and 14th centuries. In 1669 an eruption of Etna partly filled up the harbour, but spared the town, which was, however, almost entirely destroyed by the earthquake of 1693. Since that catastrophe it has been rebuilt, and has not further suffered from its proximity to Etna.

CATANZARO, a town and episcopal see of Calabria, Italy, capital of the province of Catanzaro, 1125 ft. above sea-level. Pop. (1901) 22,799 (town); 32,005 (commune). The station for the town (Catanzaro Sala) is situated on a branch line connecting the two main lines along the east and west coasts of Calabria, 6 m. N. by W. of Catanzaro Marina on the east coast, and 20 m. E. of S. Eufemia Biforcazione, on the west coast line. The town enjoys a comparatively cool climate in summer, and commands fine views. Numerous wealthy families reside here, and the town has a trade in olive-oil, silk and velvet. The castle, built by Robert Guiscard, has been modernized, and so has the cathedral. The see was founded in 1121. The provincial museum contains antiquities and especially coins from the ancient cities of Magna Graecia, and a few pictures.

CATAPHYLL (Gr. κατά, down, φύλλον, leaf), a botanical term for the early leaf-forms produced in the lower part of a shoot, such as bud-scales, or scales on underground stems.

CATAPULT (Lat. catapulta, Gr. καταπέλτης) a generic name for warlike engines of the cross-bow type used by the ancients. Although engines of war appear on Assyrian remains, and are mentioned in 2 Chronicles xxvi. 15, it appears that Greek armies, even of the 5th century, did not possess them, and the first record of a large siege train in classical literature is of the year 399 b.c., when Dionysius I. of Syracuse, contemplating an expedition against Carthage, provided himself with engines. From Sicily siege engines found their way some years later into Greece; they were used by Philip of Macedon at the siege of Byzantium in 340, and thereafter, as a natural consequence of the regularizing or professionalizing of armies, artillery, as we may call it, came into prominence and called into existence technical corps to work it.

The war engines of the Romans, during the republic and early principate, are of the same type as those of Alexander’s successors in Greece. They are usually classed as (a) catapults and (b) ballistae (λιθοβόλοι). The former were smaller and were used with arrows for what is now called direct fire (i.e. at low angles of elevation); the latter were large siege engines discharging heavy bolts or stones at a high angle of elevation, like the modern howitzer. They were, of course, principally siege engines, but the smaller natures of catapult appear in field warfare from time to time, and eventually, during the early principate, they are found as part of the regulation equipment of infantry units. Both were constructed on the same principle.

The essential parts of the catapult (see illustration) were the frame, the propelling gear, the trough (corresponding to the modern barrel) and the pedestal. The frame consisted of two horizontal beams forming top and bottom sills, and four strong upright bars mortised into them. The three open spaces or compartments, resembling narrow windows, between these four uprights carried the propelling and laying gear. The propelling gear occupied the two outer “windows.” In each a thick skein of cord or sinews was fastened to the top and bottom sills and tightly twisted. Two stiff wooden arms were inserted in the two skeins, and a specially strong bowstring joined the tips of these arms. In the middle compartment was the hinged fore-end of the trough, which was at right angles to the frame and at the back of it. The trough could be laid for elevation by a movable prop, the upper end of which was hinged to the trough, while the lower ran up and down a sort of trail fastened to the pedestal. The whole equipment was laid for “line” by turning the frame, and with it the trough, prop and trail by a pivot in the head of the pedestal. Sliding up and down in the trough was a block, fitted with a trigger mechanism, through which passed the middle of the bowstring. The pedestal was a strong and solid upright resting upon, and strutted to, a framework on the ground; its upper end, as mentioned above, took the pivot of the frame and the head of the trail.

On coming into action the machine was laid for direction and elevation. The block and with it the bowstring was next forced back against the resistance of the twisted skeins to the rear end of the trough, this being effected by a windlass attachment. The trigger being then pressed or struck with a hammer, the bowstring was released from the block, the stiff arms were violently brought back to the frame by the untwisting of the skeins, and the arrow was propelled through the centre “window” with great velocity. A small machine of the type described weighed about 85 ℔, and sent a “three-span” (26-in.) arrow weighing ½ ℔ at an effective man-killing velocity somewhat over 400 yds.

The ballista was considerably larger and more expensive than this. In Scipio’s siege train, at the attack of New Carthage (Livy xxvi. 47. 5), the number of the ballistae was only one-sixth that of the catapults. In the ballista the rear end of the trough (which projected in front of the frame) always rested upon the ground, or rather was fixed to the framework of the pedestal—which was a heavy trestle construction—and the trough was thus restricted to the angle of elevation, giving the maximum range (45°). Even so the range was not appreciably greater than that of a catapult, and in the case of the largest ballistae (ninety-pounder) it was much less. These enormous engines, which, once in position, could not be laid on any fresh target, were used for propelling beams and stones rather than for shooting arrows, that is, more for the destruction of material than for man-killing effect. The skeins that supplied the motive force of all these engines were made of the sinews of animals, twisted raw hide, horsehair rope, and, in at least one celebrated case, of women’s hair. In 146 b.c., the authorities of Carthage having surrendered their engines to the Romans in the vain hope of staying their advance, new ones were hurriedly constructed, and the women and virgins of the city cut off their hair to supply the needed skeins.

The modern implement known as a “catapult” is formed by a forked stick, to the forks of which are attached the ends of a piece of elastic. To the middle of this elastic a pocket is fitted to contain a bullet or small stone. In use the forked stick is held in the left hand and the pocket drawn back with the right. Aim is taken and, the pocket being released, the missile flies through the fork of the stick. Though classed as a toy, this weapon can do considerable execution among birds, &c., when skilfully used. The name of “catapult” has also been given to a bowling machine which is used for cricket practice.

CATARACT (from the Lat. form cataracta of the Gr. καταρράκτης, a floodgate, or waterfall, properly something which rushes down), a downpour of water, a waterfall. The earliest use in English is of a floodgate or portcullis, and this survives in the name of a disease of the eye (see [Eye]: Eye Diseases), in which the crystalline lens becomes opaque, and forms an apparent grating over the eye. The term is also used of a device to regulate the strokes in certain types of steam-engine.

CATARGIU (or Catargi), LASCAR (1823-1899), Rumanian statesman, was born in Moldavia in November 1823. He belonged to an ancient Walachian family, one of whose members had been banished in the 17th century by Prince Matthew Bassaraba, and had settled in Moldavia. Under Prince Gregory Ghica (1849-1856), Catargiu rose to be prefect of police at Jassy. In 1857 he became a member of the Divan ad hoc of Moldavia, a commission elected in accordance with the treaty of Paris (1856) to vote on the proposed union of Moldavia and Walachia. His strongly conservative views, especially on agrarian reform, induced the Conservatives to support him as a candidate for the throne in 1859. During the reign of Prince Cuza (1859-1866), Catargiu was one of the Opposition leaders, and received much assistance from his kinsman, Barbu Catargiu (b. 1807), a noted journalist and politician, who was assassinated at Bucharest on the 20th of June 1862. On the accession of Prince Charles in May 1866, Lascar Catargiu became president of the council, or prime minister; but, finding himself unable to co-operate with his Liberal colleagues, I.C. Bratianu and C.A. Rosetti, he resigned in July. After eight more ministerial changes, culminating in the anti-dynastic agitation of 1870-1871, Catargiu formed, for the first time in Rumanian history, a stable Conservative cabinet, which lasted until 1876. His policy, which averted revolution and revived the popularity of the crown, was regarded as unpatriotic and reactionary by the Liberals, who resumed office in 1876; and a proposal to impeach the whole Catargiu cabinet was only withdrawn in 1878. Catargiu remained in opposition until 1889, when he formed another cabinet, taking the portfolio of the Interior; but this administration fell after seven months. In the Florescu ministry of March 1891 he occupied the same position, and in December he again became president of the council, retaining office until 1895. During this period he was responsible for several useful reforms, chiefly financial and commercial. He died suddenly at Bucharest on the 11th of April 1899.

CATARRH (from the Gr. καταρρεῖν, to flow down), a term principally employed to describe a state of irritation of the mucous membrane of the respiratory passages, or what is called in popular language a “cold.” It is the result of infection by a micro-organism in one or more of various predisposing conditions, damp, chill, fatigue, &c. The complaint usually begins as a nasal catarrh or coryza (Gr. κόρυς, head), with a feeling of weight about the forehead and some degree of difficulty in breathing through the nose, increased on lying down. Fits of sneezing accompanied with a profuse watery discharge from the nostrils and eyes soon follow, while the sense of smell and to some extent that of taste become considerably impaired. There is usually present some amount of sore throat and of bronchial irritation, causing hoarseness and cough. Sometimes the vocal apparatus becomes so much inflamed (laryngeal catarrh) that temporary loss of voice results. There is always more or less feverishness and discomfort, and frequently an extreme sensitiveness to cold. After two or three days the symptoms begin to abate, the discharge from the nostrils and chest becoming thicker and of purulent character, and producing when dislodged considerable relief to the breathing. On the other hand the catarrh may assume a more severe aspect and pass into some form of pulmonary inflammation (see [Bronchitis]) or influenza (q.v.).

When the symptoms are first felt it is well to take a good purge, and to encourage free perspiration by a hot bath, some diaphoretic drug, as spirits of nitrous ether, being taken before retiring to bed. Some of the older school of physicians still pin their faith to a dose of Dover’s powder. When the cold manifests itself by aches and pains in back and limbs, aspirin taken three or four times in the first twenty-four hours will often act like magic. Locally a snuff made of menthol 1 part, ammonium chloride 3 parts and boracic acid 2 parts will relieve the discomfort of the nose. Also, remembering the microbic origin of the disease, gargling and nasal syringing should be repeated at intervals. As soon as the attack shows signs of subsiding, a good tonic and, still better, a change of air are very helpful.

The term catarrh is used in medical nomenclature in a wider sense to describe a state of irritation of any mucous surface in the body, which is accompanied with an abnormal discharge of its natural secretion, hence the terms gastric catarrh, intestinal catarrh, &c.

CATARRHINE APE, the term used to describe those apes which have the nostrils approximated, the aperture pointing downward, and the intervening septum narrow; distinguishing features of both the lower “doglike” apes (Cynomorpha) and the higher “manlike” apes (Anthropomorpha). The Catarrhini are restricted entirely to the Old World, and include the gorilla, the chimpanzee and orang-utan.

CATASTROPHE (Gr. καταστροφή, from καταστρέφειν, to overturn), a term of the ancient Greek drama for the change in the plot which leads up to the conclusion. The word is thus used of any sudden change, particularly of a violent or disastrous nature, and in geology of a cataclysm or great convulsion of the earth’s surface.

CATAUXI, a numerous cannibal tribe of South American Indians of the Purus river district, Brazil. They are a fine warlike race, with remarkably clear complexions and handsome features; round wrists and ankles they wear rings of twisted hair. They cultivate mandioc, and make pottery and bark canoes.

CATAWBAS (from the Choctaw for “divided”), a tribe of North American Indians of Siouan stock; formerly the dominant people of South Carolina. Some of their divisions extended into North Carolina. They are now almost extinct, but were at one time able to send nearly 2000 “braves” into battle. In the American War of Independence they furnished a valuable contingent to the South Carolina troops. They then occupied a number of small towns on the Catawba river, but they afterwards leased their land and removed to the territory of the Cherokees, with whom they had been formerly at war. There, however, they did not long remain, but returned to a reservation in their original district. Their affinities have not been very clearly made out, and by Albert Gallatin they were grouped with the Cherokees, Choctaws, Muskogees and Natchez. A vocabulary of sixty of their words was published by Horatio Hale in vol. ii. of the Transactions of the American Ethnological Society in 1848; and a much fuller list—about 300—collected by Oscar M. Lieber, the geologist, in 1856, made its appearance in vol. ii. of Collections of the South Carolina Historical Society, 1858. Of the one hundred Catawbas still said to be surviving, few, if any, can claim to be full-blooded. They are in the Catawba Reservation in York county, South Carolina. The name is familiar in connexion with the white American wine, the praises of which have been sung by Longfellow. The grape from which the wine is obtained was first discovered about 1801, near the banks of the Catawba river, and named by Major Adlum in 1828, but it is now cultivated extensively in Illinois, Ohio and New York, and especially on the shores of Lake Erie.

CATCH THE TEN, sometimes Called Scotch Whist, a game played with a pack of 36 cards, from ace, king, queen to six in each suit, the ace being highest both in play and cutting. In trumps, however, the knave ranks highest. Any number from two to eight may play. If an even number, partners are cut for; if odd, each plays for himself. An odd number of players sit as they like; four players sit as at whist; six playing in two sides sit so that no two partners shall be next each other; six playing three sides sit so that two opponents shall divide each pair; eight are arranged in alternate pairs. After cutting, the cards are dealt according to the number of players. The last card is turned up for the trump. When five or seven play, the six of spades is usually omitted; when eight play, the four sixes are thrown out. The eldest hand leads any card he chooses and all must follow suit if able, the penalty for a revoke being the loss of the game. The tricks are not kept separate but gathered in by one player for his side. At the end of the deal there are six hands of six cards on the table. The players first play out the first two hands, next the second two and finally the last two, the trump card remaining on the table until the first four hands are played out. The game is 41 points, the object of the play being to win the cards which have a special value. These are, with their values: knave of trumps 11, ace of trumps 4, king of trumps 3, queen of trumps 2, ten of trumps 10. All other cards have no counting value. As the ten can be taken by any other honour the object is to “catch the ten.”

CATECHISM (from Gr. κατηχεῖν, teach by word of mouth), a compendium of instruction (particularly of religious instruction) arranged in the form of questions and answers. The custom of catechizing, common to all civilized antiquity, was followed in the schools of Judaism and in the Early Church, where it helped to preserve the Gospel narrative (see [Catechumen]).

The catechism as we know it is intended primarily for children and uneducated persons. Its aim is to instruct, and it differs from a creed or confession in not being in the first instance an act of worship or a public profession of belief. The first regular catechisms seem to have grown out of the usual oral teaching of catechumens, and to have been compiled in the 8th and 9th centuries. Among them the work of Notker Labeo and of Kero, both monks of St Gall, and that of Ottfried of Weissenburg in Alsace deserve mention. But it is not until the first stirrings of revolt against the hierarchy, which preceded the Reformation, that they became at all widespread or numerous. The Waldenses of Savoy and France, the Brethren (small communities of evangelical dissenters from the medieval faith) of Germany, and the Unitas Fratrum of Bohemia all used the same catechism (one that was first printed in 1498, and which continued to be published till 1530) for the instruction of their children. It was based on St Augustine’s Enchiridion, and considers (a) Faith, i.e. the Creed, (b) Hope, i.e. the Lord’s Prayer, and (c) Love, i.e. the Decalogue.

The age of the Reformation gave a great stimulus to the production of catechisms. This was but natural at a time when the invention of printing had thrown the Bible open to all, and carried the war of religious opinion from the schools into the streets. The adherents of the “old” and the “new” religions alike had to justify their views to the unlearned as well as to the learned, and to give in simple formulas their reasons for the faith that was in them. Moreover, in the universal unrest and oversetting of all authority, Christianity itself was in danger of perishing, not only as the result of the cultured paganism of the Renaissance, but also through the brutish ignorance of the common folk, deprived now of their traditional religious restraints. To the urgency of this peril the reformers were fully alive; and they sought its remedy in education. “Let the people be taught,” said Luther, “let schools be opened for the poor, let the truth reach them in simple words in their own mother tongue, and they will believe.”

Catechisms of the Chief Religious Communions.—(a) Evangelical (Lutheran and Reformed).—It was the ignorance of the peasantry, as revealed by the horrors of the Peasants’ War of 1524-25, and his pastoral visitation of the electorate of Saxony 1525-1527, that drew the above exclamation from Luther, and impelled him to produce his two famous catechisms (1529). In 1520 he had brought out a primer of religion dealing briefly with the Decalogue, the Creed and the Lord’s Prayer; and Justus Jonas, Johannes Agricola and other leaders had done something of the same kind. Now all these efforts were superseded by Luther’s Smaller Catechism meant for the people themselves and especially for children, and by his Larger Catechism intended for clergy and schoolmasters. These works, which did much to mould the character of the German people, were set among the doctrinal standards of the Lutheran Church and powerfully influenced other compilations. The Smaller Catechism, with the Augsburg Confession, was made the Rule of Faith in Denmark in 1537.

In this same year (1537) John Calvin at Geneva published his catechism for children. It was called Instruction and Confession of Faith for the Use of the Church of Geneva (a reprint edited by A. Rilliet and T. Dufour Was published in 1878), and explained the Decalogue, the Apostles’ Creed, the Lord’s Prayer and the Sacraments. Though it was meant, as he said, to give expression to a simple piety rather than to exhibit a profound knowledge of religious truth, it was the work of a man who knew little of the child mind, and, though it served as an admirable and transparent epitome of his famous Institutes, it was too long and too minute for the instruction of children. Calvin came to see this, and in 1542, after his experience in Strassburg, drafted a new one which was much more suitable for teaching purposes, though, judged by modern standards, still far beyond the theological range of childhood. It was used at the Sunday noon instruction of children, on which Calvin laid much stress, and was adopted and similarly used by the Reformed Church of Scotland. The Reformed churches of the Palatinate, on the other hand, used the Heidelberg Catechism (1562-1563), “sweet-spirited, experiential, clear, moderate and happily-phrased,” mainly the work of two of Calvin’s younger disciples, Kaspar Olevianus and Zacharias Ursinus. The Heidelberg Catechism, set forth by order of the elector, is perhaps the most widely accepted symbol of the Calvinistic faith, and is noteworthy for its emphasis on the less controversial aspects of the Genevan theology. As revised by the synod of Dort in 1619, this catechism became the standard of most of the Reformed churches of central Europe, and in time of the Dutch and German Reformed churches of America. Other compilations were those of Oecolampadius (Basel, 1526), Leo Juda (Zürich, 1534), and Bullinger (Zürich, 1555). In France, after Calvin’s day, the Reformed church used besides Calvin’s book the catechisms of Louis Capell (1619), and Charles Drelincourt (1642), and at the present time Bonnefon’s Nouveau Catéchisme élémentaire (14th ed., 1900) seems most in favour. In Scotland both Calvin’s Geneva Catechism and then the Heidelberg Catechism were translated by order of the General Assembly and annotated. In 1592 these were superseded by that of John Craig, for a time the colleague of John Knox at the High Church, Edinburgh.

Since 1648 the standard Presbyterian catechisms have been those compiled by the Westminster Assembly, presented to parliament in 1647, and then authorized by the General Assembly of the Church of Scotland (July 1648) and by the Scottish parliament (January 1649). The Larger Catechism is “for such as have made some proficiency in the knowledge of the Christian religion,” but is too detailed and minute for memorizing, and has never received anything like the reception accorded to the Shorter Catechism, which is “for such as are of weaker capacity.” The work was done by a committee presided over first by Herbert Palmer, master of Queens’, Cambridge, and then by Anthony Tuckney, master of Emmanuel. The scriptural proof texts were added at the request of the English parliament. In his negotiations with the parliament in 1648 Charles I. offered to license the printing of the catechism, but, as the negotiations were broken off, this was not done. The Shorter Catechism, after a brief introduction on the end, rule and essence of religion, is divided into two parts:—I. The doctrines we are to believe (1) concerning the nature of God, (2) concerning the decrees of God and their execution—(a) in creation and providence, (b) in the covenant of works, (c) in the covenant of grace; II. The duties we are to perform (1) in regard to the moral law, (2) in regard to the gospel—(a) inward duties, i.e. faith and repentance, (b) outward duties as to the Word, the sacraments and prayer. It has 107 questions and answers, while that of the Anglican Church has but 24, grouping as it does the ten commandments and also the petitions of the Lord’s Prayer, instead of dealing with them singly. Though the Shorter Catechism, closely associated as this has been from the first with Scottish public elementary education, has had very great influence in forming and training the character of Presbyterians in Scotland, America and the British colonies, it is, like most other catechisms drawn up by dogmatic theologians, more admirable as an epitome of a particular body of divinity than as an instruction for the young and the unlearned. Its use is now generally preceded by something more adapted to the child-mind, and this is true also in other communions and in the case of other catechisms.

(b) Roman Catholic.—There was no universal catechism published by the Latin Church before the council of Trent, but several provincial councils, e.g. in Germany and Scotland (where Archbishop Hamilton’s catechism appeared in 1552 and was ordered to be read in church by the parish priest), moved in self-defence along the lines already adopted by the reformers. The council of Trent in 1563 resolved on an authoritative work which was finally carried through by two small papal commissions, and issued in 1566 by Pius V. (Eng. trans, by Donovan, Dublin, 1829). Being uncatechetical in form and addressed to the clergy rather than to the people, it missed its intention, and was superseded by others of less exalted origin, especially by those of the Jesuit Peter Canisius, whose Summa Doctrinae et Institutionis Christianae (1554) and its shorter form (1556) were already in the field. The catechisms of Bellarmine (1603) and Bossuet (1687) had considerable vogue, and a summary of the former known as Schema de Parvo was sanctioned by the Vatican council of 1870. But the Roman Catholic Church as a whole has never had any one official catechism, each bishop being allowed to settle the matter for his own diocese. In England the Roman Catholic bishops have agreed on the use of what is known as “The Penny Catechism,” which is very lucid and well constructed.

(c) Orthodox Eastern Church.—Peter Mogilas, metropolitan of Kiev, drew up in 1643 the Orthodox Confession of the Catholic and Apostolic Eastern Church. This bulwark against the encroachments of the Jesuits and the Reformed Church was standardized by the synod of Jerusalem in 1672. A smaller catechism was drawn up by order of Peter the Great in 1723. The catechisms of Levshin Platon (1762) and V.D. Philaret (1839), each in his day metropolitan of Moscow, are bulky compilations which cannot be memorized, though there is a short introductory catechism prefaced to Philaret’s volume (Eng. trans, in Blackmore’s Doctrine of the Russian Church, 1845). These works are not to any extent in the hands of the people, but are used by the Russian clergy and schoolmasters as guides in giving instruction. The Coptic and Armenian churches also have what H. Bonar describes as “mere pretences at catechisms.”

(d) Anglican.—The catechism of the Church of England is included in the Book of Common Prayer between the Orders for Baptism and Confirmation. It has two parts: (i.) the baptismal covenant, the Creed, the Decalogue and the Lord’s Prayer, drawn up probably by Cranmer[1] and Ridley in the time of Edward VI., and variously modified between then (1549) and 1661; (ii.) the meaning of the two sacraments, written on the suggestion of James I. at the Hampton Court Conference in 1604 by John Overall, then dean of St Paul’s, and afterwards bishop successively of Coventry and Lichfield and of Norwich. This supplement to what had become known as the Shorter Catechism established its use as against the longer one, King Edward VIth’s Catechisme, which had been drawn up in 1553 by John Ponet or Poynet, bishop of Winchester, and then revised and enlarged in 1570 by Alexander Nowell, Overall’s predecessor as dean of St Paul’s. The Anglican catechism with occasional modification, especially in the sacramental section, is used not only in the Church of England but in the Episcopal churches of Ireland, Scotland, the British dominions and the United States of America. By the rubric of the Prayer Book and by the 59th canon of 1603 the clergy are enjoined to teach the catechism in church on Sundays and holidays after the second lesson at Evening Prayer. This custom, long fallen into disuse, has largely been revived during recent years, the children going to church for a special afternoon service of which catechizing is the chief feature. Compared with the thoroughness of most other catechisms this one seems very scanty, but it has a better chance of being memorized, and its very simplicity has given it a firm hold on the inner life and conscience of devout members of the Anglican communion throughout the world.

(e) Other Communions.—Almost every section of the church, e.g. the Wesleyan Methodist, has its catechism or catechisms, but in addition to those already enumerated only a few need be mentioned. The Socinians embodied their tenets in the larger and smaller works drawn up by Fausto Sozzini and Schmalz, and published at Rakow in Poland in 1605;[2] modern Unitarians have modern catechisms. The Quakers or Friends possess a kind of catechism said to have been written by George Fox in 1660, in which father and son are respectively questioner and answerer, and an interesting work by Robert Barclay, in which texts of Scripture form the replies. Congregationalists for some time used Isaac Watts’s Catechisms for Children and Youth (1730), since superseded by the manuals of J.H. Stowell, J.H. Riddette and others. In 1898 the National Council of the Evangelical Free Churches in England and Wales published an Evangelical Free Church Catechism, the work of a committee (convened by Rev. Hugh Price Hughes) comprising Congregationalists, Baptists, Methodists (Wesleyan, Primitive and others), and Presbyterians, and thus representing directly or indirectly the beliefs of sixty or seventy millions of avowed Christians in all parts of the world, a striking example of inter-denominational unity. More remarkable still in some respects is The School Catechism, issued in 1907 by a conference of members of the Reformed churches in Scotland, which met on the invitation of the Church of Scotland. In its compilation representatives of the Episcopal Church in Scotland co-operated, and the book though “not designed to supersede the distinctive catechisms officially recognized by the several churches for the instruction of their own children,” certainly “commends itself as suitable for use in schools where children of various churches are taught together.”

Catechisms have a strong family likeness. In the main they are expositions of the Creed, the Lord’s Prayer and the Decalogue, and thus follow a tradition that has come down from the days when Cyril of Jerusalem delivered his catechetical Lectures. Even when (as in the Shorter Westminster Catechism and the School Catechism) the Creed is simply printed as an appendix, or where (as in the Free Church Catechism) it is not mentioned at all, its substance is dealt with. The order in which these three main themes are treated is by no means constant. The Heidelberg and Westminster Catechisms are of a more logical and independent character. The former is based on the Epistle to the Romans, and deals with the religious life as (1) Repentance, (2) Faith, (3) Love. Under these heads it discusses respectively the sin and misery of men, the redemption wrought by Christ (here are included the Creed and the Sacraments), and the grateful service of the new life (the Decalogue).

It may be noted that Sir Oliver Lodge has adopted the catechetical form in his book, The Substance of Faith Allied with Science (1907), which is described as “a catechism for parents and teachers.”

CATECHU, or Cutch (Malay, kachu), an extract obtained from several plants, its chief sources being the wood of two species of acacia (A. catechu and A. suma), both natives of India. This extract is known as black catechu. A similar extract, known in pharmacy as pale catechu (Catechu pallidum), and in general commerce as gambir, or terra japonica, is produced from the leaves of Uncaria gambir and U. acida, cinchonaceous plants growing in the East Indian Archipelago. A third product to which the name catechu is also applied, is obtained from the fruits of the areca or betel palm, Areca catechu.

Ordinary black catechu is usually imported in three different forms. The first and best quality, known as Pegu catechu, is obtained in blocks externally covered with large leaves; the second and less pure variety is in masses, which have been moulded in sand; and the third consists of large cubes packed in coarse bags. The wood of the two species of Acacia yielding catechu is taken for the manufacture when the trees have attained a diameter of about 1 ft. The bark is stripped off and used for tanning, and the trunk is split up into small fragments, which are covered with water and boiled. When the extract has become sufficiently thick it is cast into the forms in which the catechu is found in commerce. Catechu so prepared is a dark brown, or, in mass, almost black, substance, brittle, and having generally a shining lustre. It is astringent, with a sweetish taste. In cold water it disintegrates, and in boiling water, alcohol, acetic acid and strong caustic alkali it is completely dissolved. Chemically it consists of a mixture of a peculiar variety of tannin termed catechu-tannic acid with catechin or catechuic acid, and a brown substance due to the alteration of both these principles. Catechu-tannic acid is an amorphous body soluble in cold water, while catechin occurs in minute, white, silky, needle-shaped crystals, which do not dissolve in cold water. A very minute proportion of quercetin, a principle yielded by quercitron bark, has been obtained from catechu.

Gambir, which is similar in chemical composition to ordinary catechu, occurs in commerce in the form of cubes of about an inch in size, with a pale brown or yellow colour, and an even earthy fracture. For the preparation of this extract the plants above mentioned are stripped of their leaves and young twigs, and these are boiled down in shallow pans. The juice is strained off, evaporated, and when sufficiently concentrated is cast into shallow boxes, where, as it hardens and dries, it is cut into small cubes.

Gambir and catechu are extensively employed in dyeing and tanning. For dyeing they have been in use in India from the most remote period, but it was only during the 19th century that they were placed on the list of European dyeing substances. Catechu is fixed by oxidation of the colouring principle, catechin, on the cloth after dyeing or printing; and treated thus it yields a variety of durable tints of drabs, browns and olives with different mordants (see [Dyeing]). The principal consumption of catechu occurs in the preparation of fibrous substances exposed to water, such as fishing-lines and nets, and for colouring stout canvas used for covering boxes and portmanteaus under the name of tanned canvas. Black catechu is official in most pharmacopoeias except that of Great Britain, in which pale catechu is the official drug. The actions and uses of the two are similar, but black catechu is the more powerful. The dose is from five to twenty grains. The pulvis catechu compositus contains catechu and kino, and may be given in doses twice as large as those named. The drug has the actions and uses of tannic acid, but owing to the relative insolubility of catechu-tannic acid, it is more valuable than ordinary tannic acid in diarrhoea, dysentery and intestinal haemorrhage.

CATECHUMEN (Lat. catechumenus, Gr. κατηχούμενος, instructed, from κατηχεῖν, to teach orally), an ecclesiastical term applied to those receiving instruction in the principles of the Christian religion with a view to baptism. As soon as Christianity became a missionary religion, it was found necessary to make arrangements for giving instruction to new converts. At the beginning the Apostles themselves seem to have undertaken this duty, and the instruction was apparently given after baptism, for in Acts ii. 41, 42, we are told that “they that gladly received the word were baptized ... and they continued stedfastly in the Apostles’ teaching.” There are two instances in the New Testament where reference is made to individual instruction in this technical sense. Luke (i. 4) in dedicating the third Gospel to Theophilus tells him that his aim in writing the book was “that thou mightest have certainty in the things in which thou has been instructed” (κατηχήθης) and we are told that Apollos was instructed (κατηχημένος) “in the way of the Lord” (Acts xviii. 25).

With the development of Christianity the instruction became more definite and formal. It is probable that the duty of instructing converts was assigned to “the teachers,” who are ranked by Paul immediately after the Apostles and prophets (1 Cor. xii. 28), and occupied an important position in the Christian ministry. In the Didache, or Teaching of the Apostles, we have an excellent illustration of the teaching which was given to candidates for baptism in early times. There can be little doubt that the Didache was used as a manual for catechumens for several centuries. Athanasius (Festal Epistles, 39), for instance, says that “it was appointed by the Fathers to be read by those who are just recently coming to us, and wish to be instructed in the word of godliness” (κατηχεῖσθαι τὸν τῆς εὐσεβείας λόγον). The instruction prescribed by the Didache is very largely ethical, and stands in striking contrast to the more elaborate doctrinal teaching which came into vogue in later days. The Shepherd of Hermas too is another book which seems to have been used for the purpose of catechesis, for Eusebius says that it “was deemed most necessary for those who have need of elementary instruction” (Eccles. Hist. iii. 3-6).

With the rise of theological controversy and the growth of heresy catechetical instruction became of vital importance to the Church, and much greater importance was attached to it. After the middle of the 4th century it was regarded as essential that the candidate for baptism should not only be acquainted with the spiritual truths and ethical demands which form the basis of practical Christianity, but should also be trained in theology and the interpretation of the creeds. Two books have been preserved which throw a striking light upon the transformation which had taken place in the conception of catechesis; (1) the Catechetical Lectures of Cyril of Jerusalem; (2) the De rudibus Catechizandis of Augustine. Cyril’s Lectures may be termed the Pearson on the Creed of the 4th century. He takes each article separately, discusses it clause by clause, explains the meaning of each word, and justifies each statement from Scripture. Augustine’s treatise was written at the request of a catechist, named Deogratias, who had asked him for advice. After replying to the question of Deogratias, and giving sundry counsels as to the best method of interesting catechumens, Augustine concludes by giving a model catechetical lecture, in which he covers the whole of biblical history, beginning from the opening chapters of Genesis, and laying particular stress on the doctrinal parts of Scripture. Cyril and Augustine differ, as we should expect, in the doctrines which they select for emphasis, but they both agree in requiring a knowledge of sound doctrine on the part of the candidates.

In spite of the numerous references to catechumens in Patristic literature, our knowledge of the details of the system is often very deficient, and upon some points there is considerable diversity of opinion amongst experts. The following are the most important questions which come under consideration.

1. The Classification of Catechumens.—Bingham and many of the older writers held that there were four classes of catechumens, representing different stages in the process of instruction: (a) “The inquirers” whose interest in Christianity had been sufficiently aroused to make them desire further information, and who received private and individual instruction from the teachers before they were admitted into the second class, (b) “The hearers” (audientes), who were admitted into the Church for the purpose of listening to sermons and exhortations, (c) The prostrati or genu flectentes, who were allowed also to take part in the prayers, (d) The electi or competentes, who had completed the period of probation and were deemed ready to receive baptism. Modern scholars, however, for the most part, deny that there is sufficient basis to justify this elaborate classification, and think that its advocates have confused the catechumenate with the system of penance. The evidence does not seem to warrant more than two classes, (a) the audientes, who were in the initial stages of their training, (b) the competentes, who were qualified for baptism.

2. The Relation of Catechumens to the Church.—Catechumens were allowed of course to attend church services, but at a certain point were dismissed with the words “Ite catechumeni, missa est.” The moment at which the dismissal took place cannot be exactly determined, and it is not clear whether the catechumens were allowed to remain for a portion of the Communion service, and if so, whether as spectators or as partial participants. A passage in Augustine seems to imply that in some way they shared in the Sacrament, “that which they (the catechumens) receive, though it be not the Body of Christ, is yet an holy thing and more holy than the common food which sustains us, because it is a Sacrament” (De peccatorum meritis, ii. 42). The explanation of these words has occasioned considerable controversy. Many scholars hold (and this certainly seems the most natural interpretation) that consecrated bread was taken from the Eucharist and given to the catechumens. Bingham, however, maintains that the reference is not to the consecrated bread, but to salt, which was given to them as a symbol “that they might learn to purge and cleanse their souls from sin.”

3. The Duration of the Training.—Various statements with regard to the duration of the catechumenical training are found in ecclesiastical authorities. The Apostolical Constitutions, for instance, fix it at three years;[1] the synod of Elvira at two.[2] The references in the Fathers, however, imply that for practical purposes it was limited to the forty days of Lent. Very probably, however, the forty days of actual instruction were preceded by a period of probation.

4. The Relation between the Catechumenate and Baptism.—Catechetical instruction was designed as a preliminary to baptism. There were two directions, however, in which this purpose was enlarged: (a) We have no reason to suppose that when infant baptism was introduced, those who had been baptized in infancy were excluded from the catechetical training, or that instruction was deemed unnecessary in their case, though as a matter of fact we have no definite reference to their admission. The custom of postponing baptism, which was very general in the 4th and 5th centuries, probably made such cases more rare than is generally supposed, and so accounts for the absence of any allusion to them in connexion with the catechumenate. (b) We have no reason to suppose that the instruction given in the famous catechetical schools of Alexandria and Carthage was restricted to candidates for baptism. There is no doubt that “catechetical” is used in a much wider sense when applied to the lectures of Origen than when used of the addresses of Cyril of Jerusalem. The “instruction” of Origen was given to all classes of Christians, and not merely to those who were in the initial stages.

5. Characteristics of the Catechumenical Training.—Besides instruction there were some other important features connected with the catechumenate. (a) The duty of confession was impressed on the candidates. (b) The ceremony of exorcism was often performed in order to free the catechumen from evil spirits. (c) At a certain point in the training the creed and the doctrine of the Sacraments were delivered to the candidates by the bishop with much impressive ceremonial. This teaching constituted the “holy secret” or “mystery” (disciplina arcani) of Christianity, and could only be imparted to those who were qualified to receive it. The acquisition of this arcanum was regarded as the most essential element in the catechetical discipline, and marked off its possessors from the rest of the world. There can be little doubt that this conception of the “Holy Secret” came into the Church originally from the Greek mysteries, and that much of the ceremonial connected with the catechumenate and baptism was derived from the same source.

CATEGORY (Gr.: κατηγορία, “accusation”), a term used both in ordinary language and in philosophy with the general significance of “class” or “group.” In popular language it is used for any large group of similar things, and still more generally as a mere synonym for the word “class.” The word was introduced into philosophy as a technical term by Aristotle, who, however, several times used it in its original sense of “accusation.” He also used the verb κατηγορεῖν, to accuse, in the specific logical sense, to predicate; τὸ κατηγορούμενον becomes the predicate; and κατηγορικὴ πρότασις may be translated as affirmative proposition. But though the word thus received a new signification from Aristotle, it is not on that account certain that the thing it was taken to signify was equally a novelty in philosophy. In fact we find in the records of Oriental and early Greek thought something corresponding to the Aristotelian classification.

Our knowledge of Hindu philosophy, and of the relations in which it may have stood to Greek speculation, scarcely enables us to give decisive answers to various questions that naturally arise on observation of their many resemblances (see Hindu philosophy. an article by Richard Garbe in Monist, iv. 176-193). Yet the similarity between the two is so striking that, if not historically connected, they must at least be regarded as expressions of similar philosophic needs. The Hindu classification to which we specially refer is that of Kanada, who lays down six categories, or classes of existence, a seventh being generally added by the commentators. The term employed is Padārtha, meaning “signification of a word.” This is in entire harmony with the Aristotelian doctrine, the categories of which may with truth be described as significations of simple terms, τὰ κατὰ μηδεμίαν συηπλοκὴν λεγόμενα. The six categories of Kanada are Substance, Quality, Action, Genus, Individuality, and Concretion or Co-inherence. To these is added Non-Existence, Privation or Negation. Substance is the permanent substance in which Qualities exist. Action, belonging to or inhering in substances, is that which produces change, Genus belongs to substance, qualities and actions; there are higher and lower genera. Individuality, found only in substance, is that by which a thing is self-existent and marked off from others. Concretion or Co-inherence denotes inseparable or necessary connection, such as that between substance and quality. Under these six classes, γένη τοῦ ὄντος, Kanada then proceeds to range the facts of the universe.[1]

Within Greek philosophy itself there were foreshadowings of the Aristotelian doctrine, but nothing so important as to warrant the conclusion that Aristotle was directly influenced by it. Doubtless the One and Many, Being and Non-Being, of the Greek philosophy Eleatic dialectic, with their subordinate oppositions, may be called categories, but they are not so in the Aristotelian sense, and have little or nothing in common with the later system. Their starting-point and results are wholly diverse. Nor does it appear necessary to do more than mention the Pythagorean table of principles, the number of which is supposed to have given rise to the decuple arrangement adopted by Aristotle. The two classifications have nothing in common; no term in the one list appears in the other; and there is absolutely nothing in the Pythagorean principles which could have led to the theory of the categories.[2]

One naturally turns to Plato when endeavouring to discover the genesis of any Aristotelian doctrine, and undoubtedly there are in the Platonic writings many detached discussions in which the matter of the categories is touched upon. Special Plato. terms also are anticipated at various times, e.g. ποιότης in the Theaetetus, ποιεῖν and πάσχειν in the Gorgias, and πρός τι in the Sophist.[3] But there does not seem to be anything in Plato which one could say gave occasion directly and of itself to the Aristotelian doctrine; and even when we take a more comprehensive view of the Platonic system and inquire what in it corresponds to the widest definition of categories, say as ultimate elements of thought and existence, we receive no very definite answer. The Platonic dialectic never worked out into system, and only in two dialogues do we get anything like a list of ultimate or root-notions. In the Sophist, Being, Rest and Motion (τὸ ὄν αύτὸ καὶ στάσις καὶ κίνησις) are laid down as μέγιστα τῶν γενῶν.[4] To these are presently added the Same and the Other (ταὐτὁν καὶ θάτερον), and out of the consideration of all five some light is cast upon the obscure notion of Non-Being (το μὴ ὄν). In the same dialogue (262 seq.) is found the important distinction of ὄνομα and ῥῆμα, noun and verb. The Philebus presents us with a totally distinct classification into four elements—the Infinite, the Finite, the Mixture or Unity of both and the Cause of this unity (τὸ ἄπειρον, τὸ πέρας, ἡ σύμμιξις, ἡ αίτία). It is at once apparent that, however these classifications are related to one another and to the Platonic system, they lie in a different field from that occupied by the Aristotelian categories, and can hardly be said to have anything in common with them.

The Aristotelian doctrine is most distinctly formulated in the short treatise Κατηγορίαι, which generally occupies the first place among the books of the Organon. The authenticity of the treatise was doubted in early times by some of the Aristotle. commentators, and the doubts have been revived by such scholars as L. Spengel and Carl Prantl. On the other hand, C.A. Brandis, H. Bonitz, and Ed. Zeller are of opinion that the tract is substantially Aristotle’s. The matter is hardly one that can be decided either pro or con with anything like certainty; but this is of little moment, for the doctrine of the categories, even of the ten categories, does not stand or fall with only one portion of Aristotle’s works.

It is surprising that there should yet be so much uncertainty as to the real significance of the categories, and that we should be in nearly complete ignorance as to the process of thought by which, Aristotle was led to the doctrine. On both points It is difficult to extract from the matter before us anything approaching a satisfactory solution. The terms employed to denote the categories have been scrutinized with the utmost care, but they give little help. The most important—κ. τοῦ ὄντος or τῆς οὐσίας, γένη τοῦ ὄντος or τῶν ὄντων, γένη simply, τὰ πρῶτα or τὰ κοινὰ πρῶτα, αἱ πτῶσεις, or αἱ διαιρέσεις—only indicate that the categories are general classes into which Being as such may be divided, that they are summa genera. The expressions γένη τῶν κατηγορίων and σχήματα τῶν κ., which are used frequently, seem to lead to another and somewhat different view. κατηγορία being taken to mean that which is predicated, γένη τῶν κ. would signify the most general classes of predicates, the framework into the divisions of which all predicates must come. To this interpretation there are objections. The categories must be carefully distinguished from predicables; in the scholastic phraseology the former refer to first intentions, the latter to second intentions, i.e. the one denote real, the other logical connexion. Further, the categories cannot without careful explanation be defined as predicates; they are this and something more. The most important category, οὐσία, in one of its aspects cannot be predicate at all.

In the Κατηγορίαι Aristotle prefixes to his enumeration a grammatico-logical disquisition on homonyms and synonyms, and on the elements of the proposition, i.e. subject and predicate. He draws attention to the fact that things are spoken of either in the connexion known as the proposition, e.g. “a man runs,” or apart from such connexion, e.g. “man” and “runs.” He then proceeds, “Of things spoken of apart from their connexion in a proposition (τῶν κατὰ μηδεμίαν συμπλοκὴν λεγομένων), each signifies either Substance (οὐσία), or Quantity (ποσόν), or Quality (ποιόν), or Relation (πρός τι,) or Where (i.e. Place, ποῦ), or When (i.e. Time, ποτέ), or Position (κεῖσθαι), or Possession (ἔχειν), or Action (ποιεῖν), or Passion (πάσχειν). οὐσία, the first category, is subdivided into πρώτη οὐσία or primary substance, which is defined to be τόδε τι, the singular thing in which properties inhere, and to which predicates are attached, and δεύτεραι οὐσίαι, genera or species which can be predicated of primary substances, and are therefore οὐσία. only in a secondary sense. Nevertheless, they too, after a certain fashion, signify the singular thing, τόδε τι” (K. p. 3 b 12, 13). It is this doctrine of πρώτη οὐσία that has raised doubts with regard to the authenticity of the Κατηγορίαι But the tenfold classification, which has also been captiously objected to, is given in an acknowledged writing of Aristotle’s (see Topica, i. 9, p. 103 b 20).[5] At the same time it is at least remarkable that in two places where the enumeration seems intended to be complete (Met. p. 1017 a 25; An. Pos. i. 22, p. 83 a 21), only eight are mentioned, ἔχειν and κεῖσθαι being omitted. In other passages[6] six, five, four, and three are given, frequently with some addition, such as καὶ αἱ ἄλλαι κ. It is also to be observed that, despite of this wavering, distinct intimations are given by Aristotle that he regarded his list as complete, and he uses phrases which would seem to indicate that the division had been exhaustively carried out. He admits certainly that some predicates which come under one category might be referred to another, but he declines to deduce all from one highest class, or to recognize any relation of subordination among the several classes.

The full import of the categories will never be adequately reached from the point of view taken up in the Κατηγορίαι, which bears all the marks of an early and preliminary study. For true understanding we must turn to the Metaphysics, where the doctrine is handled at large. The discussion of Being in that work starts with a distinction that at once gives us a clue. τὸ ὄν is spoken of in many ways; of these four are classified—τὸ ὄν κατὰ συμβεβηκός, τὸ ὄν ὼς ὰληθές, τὸ ὄν δυνάμει καὶ ἑνεργείᾳ, and τὸ ὄν κατὰ τὰ σχήματα τῶν κατηγορίων. It is evident from this that the categories can be regarded neither as purely logical nor as purely metaphysical elements. They indicate the general forms or ways in which Being can be predicated; they are determinations of Being regarded as an object of thought, and consequently as matter of speech. It becomes apparent also why the analysis of the categories starts from the singular thing, for it is the primary form under which all that is becomes object of knowledge, and the other categories modify or qualify this real individual. Πάντα δὲ τὰ γιγνόμενα ὑπό τέ τινος γίγνεται καὶ ἔκ τινος καὶ τὶ. Τὸ δὲ τὶ λέγω καθ᾽ ἑκάστην κατηγορίαν᾽ ἢ γὰρ τόδε ἢ ποσὸν ἢ ποιὸν ἢ ποῦ (Met. p. 1032 a 13-15).... The categories, therefore, are not logical forms, but real predicates; they are the general modes in which Being may be expressed. The definite thing, that which comes forward in the process from potentiality to full actuality, can only appear and be spoken of under forms of individuality, quality, quantity and so on. The nine later categories all denote entity in a certain imperfect fashion.

The categories then are not to be regarded as heads of predicates, the framework into which predicates can be thrown. They are real determinations of Being—allgemeine Bestimmtheiten, as Hegel calls them. They are not summa genera of existences, still less are they to be explained as a classification of namable things in general. The objections Mill has taken to the list are entirely irrelevant, and would only have significance if the categories were really—what they are not—an exhaustive division of concrete existences. Grote’s view (Aristotle, i. 108) that Aristotle drew up his list by examining Various popular propositions, and throwing the different predicates into genera, “according as they stood in different logical relation to the subject,” has no foundation. The relation of the predicate category to the subject is not entirely a logical one; it is a relation of real existence, and wants the essential marks of the prepositional form. The logical relations of τὸ ὂν are provided for otherwise than by the categories.

Aristotle has given no intimation of the course of thought by which he was led to his tenfold arrangement, and it seems hopeless to discover it. Trendelenburg in various essays has worked out the idea that the root of the matter is to be found in grammatical considerations, that the categories originated from investigations into grammatical functions, and that a correspondence will be found to obtain between categories and parts of speech. Thus, Substance corresponds to noun substantive, Quantity and Quality to the adjective, Relation partly to the comparative degree and perhaps to the preposition, When and Where to the adverbs of time and place. Action to the active, Passion to the passive of the verb, Position (κεῖσθαι) to the intransitive verb, ἔχειν to the peculiar Greek perfect. That there should be a very close correspondence between the categories and grammatical elements is by no means surprising; that the one were deduced from the other is both philosophically and historically improbable. Reference to the detailed criticisms of Trendelenburg by Ritter, Bonitz, and Zeller will be sufficient.

Aristotle has also left us in doubt on another point. Why should there be only ten categories? and why should these be the ten? Kant and Hegel, it is well known, signalize as the great defect in the Aristotelian categories the want of a principle, and yet some of Aristotle’s expressions would warrant the inference that he had a principle, and that he thought his arrangement exhaustive. The leading idea of all later attempts at reduction to unity of principle, the division into substance and accident, was undoubtedly not overlooked by Aristotle, and Fr. Brentano[7] has collected with great diligence passages which indicate how the complete list might have been deduced from this primary distinction. His tabular arrangements (pp. 175, 177) are particularly deserving of attention. The results, however, are hardly beyond the reach of doubt.

There was no fundamental change in the doctrine of the categories from the time of Aristotle to that of Kant, and only two proposed reclassifications are of such importance as to require notice. The Stoics adopted a fivefold arrangement of Later Greek. highest classes, γενικώτατα. τὸ ὄν or τὶ, Being, or somewhat in general, was subdivided into ὑποκείμενα or subjects, ποιά or qualities in general, which give definiteness to the blank subject, πὼς ἔχοντα, modes which further determine the subject, and πὼς ἔχοντα, definite relative modes. These categories are so related that each involves the existence of one higher than itself, thus there cannot be a πρός τι πὼς ἔχον which does not rest upon or imply a πὼς ἔχον, but πὼς ἔχον is impossible without ποιόν, which only exists in ὑποκείμενον, a form or phase of τὸ ὄν.[8]

Plotinus, after a lengthy critique of Aristotle’s categories, sets out a twofold list. τὸ ἔν, κίνησις, στάσις, ταὐτότης, ἑτερότης are the primitive categories (πρῶτα γένη) of the intelligible sphere. οὐσία, πρός τι, ποιά, ποσόν, κίνησις are the categories of the sensible world. The return to the Platonic classification will not escape notice.

Modern philosophy, neglecting altogether the dry and tasteless treatment of the Aristotelian doctrine by scholastic writers, gave a new, a wider and deeper meaning to the categories. They now appear as ultimate or root notions, the metaphysical Modern philosophy. or thought elements, which give coherence and consistency to the material of knowledge, the necessary and universal relations which obtain among the particulars of experience. There was thus to some extent a return to Platonism, but in reality, as might easily be shown, the new interpretation was, with due allowance for difference in point of view, in strict harmony with the true doctrine of Aristotle. The modern theory dates in particular from the time of Kant, who may be said to have reintroduced the term into philosophy. Naturally there are some anticipations in earlier thinkers. The Substance, Attribute and Mode of Cartesianism can hardly be classed among the categories; nor does Leibnitz’s chance suggestion of a fivefold arrangement into Substance, Quantity, Quality, Action and Passion, and Relations, demand any particular notice. Locke, too, has a classification into Substances, Modes and Relations, but in it he has manifestly no intention of drawing up a table of categories. What in his system corresponds most nearly to the modern view of these elements is the division of kinds of real predication. In all judgments of knowledge we predicate either (1) Identity or Diversity, (2) Relation, (3) Co-existence, or necessary connexion, or (4) Real existence. From this the transition was easy to Hume’s important classification of philosophical relations into those of Resemblance, Identity, Time and Place, Quantity or Number, Quality, Contrariety, Cause and Effect.

These attempts at an exhaustive distribution of the necessary relations of all objects of knowledge indicate the direction taken by modern thought, before it received its complete expression from Kant.

The doctrine of the categories is the very kernel of the Kantian system, and, through it, of later German philosophy. To explain it fully would be to write the history of that philosophy. The categories are called by Kant Root-notions of the Kant. Understanding (Stammbegriffe des Verstandes), and are briefly the specific forms of the a priori or formal element in rational cognition. It is this distinction of matter and form in knowledge that marks off the Kantian from the Aristotelian doctrine. To Kant knowledge was only possible as the synthesis of the material or a posteriori with the formal or a priori. The material to which a priori forms of the understanding were applied was the sensuous content of the pure intuitions, Time and Space. This content could not be known by sense, but only by intellectual function. But the understanding in the process of knowledge makes use of the universal form of synthesis, the judgment; intellectual function is essentially of the nature of judgment or the reduction of a manifold to unity through a conception. The specific or type forms of such function will, therefore, be expressed in judgments; and a complete classification of the forms of judgments is the key by which one may hope to discover the system of categories. Such a list of judgments Kant thought he found in ordinary logic, and from it he drew up his well-known scheme of the twelve categories. These forms are the determinations of all objects of experience, for it is only through them that the manifold of sense can be reduced to the unity of consciousness, and thereby constituted experience. They are a priori conditions, subjective in one sense, but objective as being universal, necessary and constitutive of experience.

The table of logical judgments with corresponding categories is as follows:—

Kant, it is well known, criticizes Aristotle severely for having drawn up his categories without a principle, and claims to have disclosed the only possible method by which an exhaustive classification might be obtained. What he criticized in Aristotle is brought against his own procedure by the later German thinkers, particularly Fichte and Hegel. And in point of fact it cannot be denied that Kant has allowed too much completeness to the ordinary logical distribution of propositions; he has given no proof that in these forms are contained all species of synthesis, and in consequence he has failed to show that in the categories, or pure conceptions, are contained all the modes of a priori synthesis. Further, his principle has so far the unity he claimed for it, the unity of a single function, but the specific forms in which such unity manifests itself are not themselves accounted for by this principle. Kant himself hints more than once at the possibility of a completely rational system of the categories, at an evolution from one single movement of thought, and in his Remarks on the Table of the Categories gave a pregnant hint as to the method to be employed. From any complete realization of this suggestion Kant, however, was precluded by one portion of his theory. The categories, although the necessary conditions under which alone an object of experience can be thrown, are merely forms of the mind’s own activity; they apply only to sensuous and consequently subjective material. Outside of and beyond them lies the thing-in-itself, which to Kant represented the ultimately real. This subjectivism was a distinct hiatus in the Kantian system, and against it principally Fichte and Hegel directed criticism. It was manifest that at the root of the whole Fichte. system of categories there lay the synthetizing unity of self-consciousness, and it was upon this unity that Fichte fixed as giving the possibility of a more complete and rigorous deduction of the pure notions of the understanding. Without the act of the Ego, whereby it is self-conscious, there could be no knowledge, and this primitive act or function must be, he saw, the position or affirmation of itself by the Ego. The first principle then must be that the Ego posits itself as the Ego, that Ego = Ego, a principle which is unconditioned both in form and matter, and therefore capable of standing absolutely first, of being the prius in a system. Metaphysically regarded this act of self-position yields the categories of Reality. But, so far as matter is concerned, there cannot be affirmation without negation, omnis determinatio est negatio. The determination of the Ego presupposes or involves the Non-Ego. The form of the proposition in which this second act takes to itself expression, the Ego is not = Not-Ego, is unconditioned, not derivable from the first. It is the absolute antithesis to the primitive thesis. The category of Negation is the result of this second act. From these two propositions, involving absolutely opposed and mutually destructive elements, there results a third which reconciles both in a higher synthesis. The notion in this third is determination or limitation; the Ego and Non-Ego limit, and are opposed to one another. From these three positions Fichte proceeds to evolve the categories by a series of thesis, antithesis and synthesis.

In thus seizing upon the unity of self-consciousness as the origin for systematic development, Fichte has clearly taken a step in advance of, and yet in strict harmony with, the Kantian doctrine. For, after all that can be said as to the demonstrated character of formal logic, Kant’s procedure was empirical, and only after the list of categories had been drawn out, did he bring forward into prominence what gave them coherence and reality. The peculiar method of Fichte, also, was nothing but a consistent application of Kant’s own Remark on the Table of the Categories. Fichte’s doctrine, however, is open to some of the objections advanced against Kant. His method is too abstract and external, and wants the unity of a single principle. The first two of his fundamental propositions stand isolated from one another, not to be resolved into a primitive unity. With him, too, the whole stands yet on the plane of subjectivity. He speaks, indeed, of the universal Ego as distinct from the empirical self-consciousness; but the universal does not rise with him to concrete spirit. Nevertheless the Wissenschaftslehre contains the only real advance in the treatment of the categories from the time of Kant to that of Hegel.[9] This, of course, does not imply that there were not certain elements in Schelling, particularly in the Transcendental Idealism, that are of value in the transition to the later system; but on the whole it is only in Hegel that the whole matter of the Kantian categories has been assimilated and carried to a higher stage. The Hegelian philosophy, in brief, is a system of the categories; and, as it is not intended here to expound that philosophy, it is impossible to give more than a few general and quite external observations as to the Hegelian mode of viewing these elements of thought. With Kant, as has been seen, the categories were still subjective, not as being forms of the individual subject, but as having over against them the world of noumena to which they were inapplicable. Self-consciousness, which was, even with Kant, the nodus or kernel whence the categories sprang, was nothing but a logical centre,—the reality was concealed. There was thus a dualism, to overcome which is the first step in the Hegelian system. The principle, if there is to be one, must be universally applicable, all-comprehensive. Self-consciousness is precisely the principle wanted; it is a unity, an identity, containing in itself a multiplicity. The universal in absolute self-consciousness is just pure thinking, which in systematic evolution is the categories; the particular is the natural or multiform, the external as such; the concrete of both is spirit, or self-consciousness come to itself. The same law that obtains among the categories is found adequate to an explanation of the external thing which had so sadly troubled Kant. The categories themselves are moments of the universal of thought, type forms, or definite aspects which thought assumes; determinations, Bestimmungen, as Hegel most frequently calls them. They evolve by the same law that was found to be the essence of ultimate reality—i.e. of self-consciousness. The complete system is pure thought, the Universal par excellence.

After the Hegelian there can hardly be said to have been a philosophical treatment of the categories in Germany which is not more or less a criticism of that system. It does not seem necessary to mention the unimportant modifications introduced by Kuno Fischer, J.E. Erdmann, or others belonging to the school. In the strongly-opposed philosophy of J.F. Herbart the categories can hardly be said to hold a prominent place. They are, with him, the most general notions which are psychologically formed, and he classifies them as follows:—(1) Thing, either as product of thought or as given in experience; (2) Property, either qualitative or quantitative; (3) Relation; (4) The Negated. Along with these he posits as categories of inner process—(1) Sensation, (2) Cognition, (3) Will, (4) Action. Joh. Fr. L. George (1811-1873),[10] who in the main follows Schleiermacher, draws out a table of categories which shows, in some points, traces of Herbartian influence. His arrangement by enneads, or series of nine, is fanciful, and wanting in inner principle.

The most imposing of more recent attempts at a reconstruction of the categories is that of F.A. Trendelenburg. To him the first principle, or primitive reality, is Motion, which is both real as external movement, and ideal as inner construction. Trendelenburg. The necessary conditions of Motion are Time and Space, which are both subjective and objective. From this point onwards are developed the mathematical (point, line, &c.) and real (causality, substance, quantity, quality, &c.) categories which appear as involved in the notion of motion. Matter cannot be regarded as a product of motion; it is the condition of motion, we must think something moved. All these categories, “under the presupposition of motion as the first energy of thought, are ideal and subjective relations; as also, under the presupposition of motion as the first energy of Being, real and objective relations.”[11] A serious difficulty presents itself in the next category, that of End (Zweck), which can easily be thought for inner activity, but can hardly be reconciled with real motion. Trendelenburg solves the difficulty only empirically, by pointing to the insufficiency of the merely mechanical to account for the organic. The consideration of Modality effects the transition to the forms of logical thought. On the whole, Trendelenburg’s unique fact of motion seems rather a blunder. There is much more involved than he is willing to allow, and motion per se is by no means adequate to self-consciousness. His theory has found little favour.

Hermann Ulrici works out a system of the categories from a psychological or logical point of view. To him the fundamental fact of philosophy is the distinguishing activity (unterscheidende Tätigkeit) of thought. Thought is only possible Ulrici. by distinction, difference. The fixed points in the relations of objects upon which this activity turns are the categories, which may be called the forms or laws of thought. They are the aspects of things, notions under which things must be brought, in order to become objects of thought. They are thus the most general predicates or heads of predicates. The categories cannot be completely gathered from experience, nor can they be evolved a priori; but, by attending to the general relations of thought and its purely indefinite matter, and examining what we must predicate in order to know Being, we may attain to a satisfactory list. Such a list is given in great detail in the System der Logik (1852), and in briefer, preciser form in the Compendium der Logik (2nd ed., 1872); it is in many points well deserving of attention.

The definition of the categories by the able French logician Charles Bernard Renouvier in some respects resembles that of Ulrici. To him the primitive fact is Relation, of which all the categories are but forms. “The categories,” he says, “are the Renouvier, Cousin, Hamilton, Mill. primary and irreducible laws of knowledge, the fundamental relations which determine its form and regulate its movements.” His table and his criticism of the Kantian theory are both of interest.[12] The criticism of Kant’s categories by Cousin and his own attempted classification are of no importance. Of little more value is the elaborate table drawn out by Sir W. Hamilton.[13] The generalized category of the Conditioned has but little meaning, and the subordinate categories evolve themselves by no principle, but are arranged after a formal and quite arbitrary manner. They are never brought into connexion with thought itself, nor could they be shown to spring from its nature and relations. J.S. Mill presented, “as a substitute for the abortive classification of Existences, termed the categories of Aristotle,” the following as an enumeration of all nameable things:—(1) Feelings, or states of consciousness; (2) The minds which experience these feelings; (3) Bodies, or external objects which excite certain of those feelings; (4) Successions and co-existences, likenesses and unlikenesses, between feelings or states of consciousness.[14] This classification proceeds on a quite peculiar view of the categories, and is here presented only for the sake of completeness.

By modern psychologists the subject has been closely investigated. Professor G.F. Stout (Manual of Psychology, vol. ii. pp. 312 foll.) defines categories as “forms of cognitive consciousness, universal principles or relations presupposed either in all Modern psychologists. cognition or in all cognition of a certain kind.” He then treats External (or Physical) Reality, Space, Time, Causality and “Thinghood” from the standpoint of the perceptual consciousness; showing in what sense the categories of causality, substance and the rest exist in the sphere of perception. As contrasted with the ideational, the perceptual consciousness is concerned with practice. Perception tells the child of things as separate entities, not in their ultimate relations as parts of a coherent whole. G.T. Ladd (Psychology Descriptive and Explanatory, ch. xxi., on “Space, Time and Causality”) defines the categories from the psychological standpoint as “those highly abstract conceptions which the mind frames by reflection upon its own most general modes of behaviour. They are our own notions resulting from co-operation of imagination and judgment, concerning the ultimate and unanalyzable forms of our own existence and development.” In other words, the categories are highly abstract, have no content, and are realized as a kind of thinking which has for its object all the other mental processes.

CATENARY (from Lat. catena, a chain), in mathematics, the curve assumed by a uniform chain or string hanging freely between two supports. It was investigated by Galileo, who erroneously determined it to be a parabola; Jungius detected Galileo’s error, but the true form was not discovered until 1691, when James Bernoulli published it as a problem in the Acta Eruditorum. Bernoulli also considered the cases when (1) the chain was of variable density, (2) extensible, (3) acted upon at each point by a force directed to a fixed centre. These curves attracted much attention and were discussed by John Bernoulli, Leibnitz, Huygens, David Gregory and others.

The mechanical properties of the curves are treated in the article [Mechanics], where various forms are illustrated. The simple catenary is shown in the figure. The cartesian equation referred to the axis and directrix is y = c cosh (x/c) or y = ½c(ex/c + e−x/c); other forms are s = c sinh (x/c) and y² = c² + s², s being the arc measured from the vertex; the intrinsic equation is s = c tan ψ. The radius of curvature and normal are each equal to c sec² ψ.

The surface formed by revolving the catenary about its directrix is named the alysseide. It is a minimal surface, i.e. the catenary solves the problem: to find a curve joining two given points, which when revolved about a line co-planar with the points traces a surface of minimum area (see [Variations, Calculus of]).

The involute of the catenary is called the tractory, tractrix or antifriction curve; it has a cusp at the vertex of the catenary, and is asymptotic to the directrix. The cartesian equation is

x = √ (c² − y²) + ½c log [ {c − √ (c² − y²)} / {c + √ (c² + y²)} ],

and the curve has the geometrical property that the length of its tangent is constant. It is named the tractory, since a weight placed on the ground and drawn along by means of a flexible string by a person travelling in a straight line, the weight not being in this line, describes the curve in question. It is named the antifriction curve, since a pivot and step having the form of the surface generated by revolving the curve about its vertical axis wear away equally (see [Mechanics]: Applied).

CATERAN (from the Gaelic ceathairne, a collective word meaning “peasantry”), the band of fighting men of a Highland clan; hence the term is applied to the Highland, and later to any, marauders or cattle-lifters.

CATERHAM, an urban district in the Wimbledon parliamentary division of Surrey, England, 20 m. S. of London by the South-Eastern & Chatham railway. Pop. (1901) 9486. It lies in a healthy, hilly district, and has grown in modern times from a village into a large residential town. There are large barracks in the neighbourhood, and the Metropolitan lunatic asylum is close to the town.

CATERPILLAR, the popular name of the larva of various insects, particularly of butterflies and moths (see [Lepidoptera], [Hexapoda], [Metamorphosis]). The word appears first in the form caterpyl (Promptorium Parvulorum, about the middle of the 15th century). This may be the original form, with the addition of -ar or -er; if so, it represents the O. Fr. chatepelose or chatepeleuse, i.e. “hairy-cat” (chat, cat, and pelouse, hairy, Lat. pilosus), a name applied to the hairy caterpillar, and also according to Cotgrave to a weevil. The use of “cat” in this connexion is paralleled by the Swiss name for a caterpillar, teufelskatz, and the popular English name for the blossom of the willow, “catkin,” somewhat resembling a caterpillar (cf. “palmer”); the modern French is chenille, Latin canicula, a little dog. The termination of the word seems to have been early connected with “piller,” a robber, plunderer from the destructive habits of the larva, cf. Joel i. 4—”That which the palmer-worm hath left, hath the locust eaten.” The spelling “caterpillar,” a 17th century corruption, has been the usual form since Johnson.

CATESBY, ROBERT (1573-1605), English conspirator, son of Sir William Catesby of Lapworth in Warwickshire, a prominent recusant who was a descendant of Sir William Catesby, speaker of the House of Commons in 1484, executed by Henry VII. after the battle of Bosworth, was born in 1573, and entered Gloucester Hall (now Worcester College), Oxford, in 1586. He possessed a considerable estate, and was said to be wild and extravagant in his youth. In 1596 he was one of those arrested on suspicion during an illness of Queen Elizabeth. In 1601 he took part in the rebellion of Essex, was wounded in the fight and imprisoned, but finally pardoned on the payment of an enormous fine, to obtain which he was forced to sell a portion of his property. In 1602 he despatched Thomas Winter and the Jesuit Tesimond alias Greenway to Spain to induce Philip III. to organize an invasion of England, and in 1603, after James’s accession, he was named as an accomplice in the “Bye Plot.” Catesby was a man of great beauty of person, “above 2 yards high,” says Father Gerard, “and though slender, yet as well-proportioned to his height as any man one should see.” He possessed a clear head and unflinching courage, and with a strong determination and fascinating manner mastered the minds of his associates and overpowered all opposition. He was, however, headstrong, wilful and imprudent, fit for action, but incapable of due deliberation, and entirely wanting in foresight. Exasperated by his personal misfortunes and at the repressive measures under which his co-religionists were suffering, and blinded by a religious zeal which amounted to fanaticism, he was now to be the chief instigator of the famous Gunpowder Plot, which must in any event have brought disaster upon the Roman Catholic cause. The idea of some great stroke seems to have first entered his mind in May 1603. About the middle of January 1604 he imparted his scheme of blowing up the Parliament House to his cousin Thomas Winter, subsequently taking in Guy Fawkes and several other conspirators and overcoming all fears and scruples. But it was his determination, from which he would not be shaken, not to allow warning to be given to the Roman Catholic peers that was the actual cause of the failure of the plot. A fatal mistake had been made in imparting the secret to Francis Tresham (q.v.), in order to secure his financial assistance; and there is scarcely any doubt that he was the author of the celebrated letter to his brother-in-law, Lord Monteagle, which betrayed the conspiracy to the government, on the 26th of October. On receiving the news of the letter on the 28th, Catesby exhibited extraordinary coolness and fortitude, and refused to abandon the attempt, hoping that the government might despise the warning and still neglect precautions; and his confidence was strengthened by Fawkes’s report that nothing in the cellar had been touched or tampered with. On the 2nd of November his resolution was shaken by Tresham’s renewed entreaties that he would flee, and his positive assurance that Salisbury knew everything. On the evening of the 3rd, however, he was again, through Percy’s insistence, persuaded to stand firm and hazard the great stroke. The rest of the story is told in the article [Gunpowder Plot]. Here it need only be said that Catesby, after the discovery of the conspiracy, fled with his fellow-plotters, taking refuge ultimately at Holbeche in Staffordshire, where on the night of the 8th of November he was overtaken and killed. He had married Catherine, daughter of Thomas Leigh of Stoneleigh, Warwickshire, and left one son, Robert, who inherited that part of the family estate which had been settled on Catesby’s mother and was untouched by the attainder, and who is said to have married a daughter of Thomas Percy.

CAT-FISH, the name usually applied to the fishes of the family Siluridae, in allusion to the long barbels or feelers about the mouth, which have been compared to the whiskers of a cat. The Siluridae are a large and varied group, mostly inhabitants of fresh waters; some of them by their singular form and armature are suggestive of the Devonian mailed fishes, and were placed at one time in their vicinity by L. Agassiz. Even such authorities as T.H. Huxley and E.D. Cope were inclined to ascribe ganoid affinities to the Siluridae; but this view has gradually lost ground, and most modern ichthyologists, if not all, have adopted the conclusions of M. Sagemehl, who has placed the Siluridae near the carps and Characinids in the group Ostariophysi. The Silurids and Cyprinids may be regarded as two parallel series derived from some common stock which cannot have been very different from the existing Characinids. In spite of the archaic appearance of some of its members, the family Siluridae does not appear to extend far back in time, its oldest known representative being the Bucklandium diluvii of the Lower Eocene (London Clay) of Sheppey. A great number of forms were placed by Cuvier and his successors in the family Siluridae, which has since been broken up by T. Gill and other American authors into several families, united under the name of Nematognathi. A middle course appears the more reasonable to the present writer, who has divided the Siluridae of Cuvier into three families, with the following definitions:—

Siluridae—ribs attached to strong parapophyses; operculum well developed.

Loricariidae—ribs sessile; parapophyses absent; operculum more or less developed.

Aspredinidae—ribs sessile; strong parapophyses; operculum absent.

These three families may be defined among the Ostariophysi by having the parietal bones fused with the supraoccipital, no symplectic, the body naked or with bony scutes, the mouth usually toothed, with barbels, and usually an adipose dorsal fin.

The Siluridae embrace more than one thousand species, spread over the fresh waters of all parts of the world, but mostly from between the tropics. They are absent from western Europe and north-west Africa, and from North America west of the Rocky Mountains, but this deficiency has been made good by now, the introduction of Amiurus nebulosus and allied species in various parts of continental Europe and California having proved a success. Only a few forms are marine (Plotosus, Arius, Galeichthys).

The species which has given the name to the whole family is the “Wels” of the Germans, Silurus glanis, the largest European fresh-water fish, inhabiting the greater part of Europe from the Rhine eastwards and north of the Alps. Its head is large and broad, its mouth wide, furnished with six barbels, of which those of the upper jaw are very long. Both jaws and the palate are armed with broad bands of small closely-set teeth, which give the bones a rasp-like appearance. The eyes are exceedingly small. The short body terminates in a long, compressed, muscular tail, and the whole fish is covered with a smooth, scaleless, slippery skin. Specimens of 4 and 5 ft. in length, and of 50 to 80 ℔ in weight, are of common occurrence, and the fish grows to 10 ft., with a weight of 400 ℔, in the Danube. Its food consists chiefly of other bottom-feeding fishes, and in inland countries it is considered one of the better class of food fishes. Stories about children having been found in the stomach of very large individuals are probably inventions. An allied species (S. aristotelis) is found in Greece.

The Clarias and Heterobranchus of Africa and south-eastern Asia have an elongate, more or less eel-shaped body, with long dorsal and anal fins, and are known to be able to live a long time out of water, being provided with an accessory dendritic breathing organ situated above the gills. Some species live in burrows during the dry season, crawling about at night in search of food. The common Nile species, the “Harmoot” (Clarias lazera), occurs abundantly in the Lake of Galilee and was included in, if not chiefly aimed at, by the Mosaic law which forbade the Jews to eat scaleless fishes, a prohibition which has been extended to eels in spite of the obvious presence of minute scales in the latter.

The Saccobranchus of India and Ceylon, a genus more nearly related to Silurus, have also an accessory organ for breathing atmospheric air. It consists of a long sac behind the gill-cavity, extending far back on each side of the body under the muscles.

In the majority of the Siluridae, called by A. Gunther the Proteropterae, a section extremely numerous in species, and represented throughout the tropics, the dorsal fin consists of a short-rayed and an adipose portion, the former belonging to the abdominal vertebral column; the anal is always much shorter than the tail. The gill-membranes are not confluent with the skin of the isthmus; they have a free posterior margin. When a nasal barbel is present, it belongs to the posterior nostril. This section includes among many others the genus Bagrus, of which the bayad (B. bayad) and docmac (B. docmac) frequently come under the notice of travellers on the Nile; they grow to a length of 5 ft. and are eaten.

Of the “cat-fishes” of North America (Amiurus), locally called “bull-heads” or “horned-pouts,” with eight barbels, some twenty species are known. Some of them are valued as food, especially one which is abundant in the ponds of New England, and capable of easy introduction into other localities (A. nebulosus). Others which inhabit the great lakes (A. nigricans) and the Mississippi (A. ponderosus) often exceed the weight of 100 ℔ Platystoma and Pimelodus people the rivers and lakes of tropical America, and many of them are conspicuous in this fauna by the ornamentation of their body, by long spatulate snouts, and by their great size.

The genus Arius is composed of a great number of species and has the widest distribution of all Silurids, being represented in almost all tropical countries which are drained by large rivers. Most of the species live in salt water. They possess six barbels, and their head is extensively osseous on its upper surface; their dorsal and pectoral spines are generally developed into powerful weapons. Bagarius, one of the largest Silurids of the rivers of India and Java, exceeding a length of 6 ft., differs from Arius in having eight barbels and the head covered with skin.

R. Semon has made observations in Queensland on the habits of Arius australis, which builds nests in the sandy bed of the Burnett river. These nests consist of circular basin-like excavations about 20 in. in diameter, at the bottom of which the eggs are laid and covered over by several layers of large stones. In the marine and estuarine species of Arius, Galcichthys and Osteogeniosus, the male, more rarely the female, carries the eggs in the mouth and pharynx; these eggs, few in number, are remarkably large, measuring as much as 17 or 18 millimetres in diameter in Arius commusonii, a fish 3 or 4 ft. in length.
