The material of which they are composed is in nearly all cases the same. It is a stone of extreme hardness and of various shades of colour, from a light green to a dark olive, with a degree of transparency equal to that of wax and susceptible of a fine polish. By some writers it is called a black stone; but this colour may have been given to it by frequent handling when in use, and by the grime of age since. It was called by the Romans, from the use made of it in fabricating measures of weight, lapis æquipondus, and from its supposed efficacy in the cure of diseases of the kidneys lapis nephriticus. Fabreti says that it got the name of lapis Lydius from the locality from which it was believed to have come. It is a kind of nephrite or jade, a mineral which usually occurs in talcose or magnesian rocks. At one time it was supposed to exist only on the river Kara-Kash, in the Kuen Luen mountains north of Cashmere, and for thousands of years the mines of that locality were the only known worked ones of pure jade. It has since, however, been found in New Zealand and in India; while the discoverers of South America obtained specimens of it in its natural state from the natives of Peru, who used it for making axes and arrow-heads, and gave it the name of piedra de yjada, from which comes our common word jade, on account of its use as a supposed cure for the iliac passion. It may be mentioned that there is a mineral closely allied to jade called "Saussurite," discovered by the great geologist whose name it bears near Monte Rosa, and since found on the borders of the Lake of Geneva, near Genoa, and in Corsica. It is possible that the martyr-stones may be made of this mineral, for they have not been analysed. But if they are, as it is supposed, made of true jade, the fact opens up many important questions.
No stone has a more remarkable history. It is an object of interest alike to the geologist and the antiquarian; and in spite of the most patient inquiry its antecedents are surrounded with a mystery which cannot be satisfactorily solved. Its antiquity is beyond doubt. In the most ancient books of China it is noticed as one of the articles of tribute paid to the emperor. Dr. Schliemann found it among the ruins of Troy. But its history stretches into the misty past far anterior in time to all ordinary records, to Cyclopean constructions, or to pictured and sculptured stones. One of the most curious things brought to light in connection with the prehistoric annals of our race is the wide diffusion of this mineral in regions as far apart as China and Britain. Owing to its extreme hardness and susceptibility to polish, it was highly prized by the neolithic races for the manufacture of stone axes and hammers. In nearly every European country implements of jade belonging to the primitive inhabitants have been discovered. Some of the most beautiful belonged to one of the latest settlements of the stone age at Gerlafingen, in the Lake of Bienne, and were mixed with bronze celts of primitive type, indicating that the people of these lake-dwellings lived during the transition period between stone and bronze.
The presence of such celts made of jade obviously points to a connection at a very early period with the East, from whence the stone must have been brought, for it has never been found in a natural state west of the Caspian. An interesting controversy upon this subject was created about eight years ago by the finding in the bed of the Rhone of a jade strigil, an instrument curved and hollowed like a spoon used to scrape the skin while bathing. Various conjectures were formed as to how this isolated object could have found its way from its distant quarry in the East to this obscure spot among the Alps. Professor Max Müller, and those who along with him advocate the Oriental origin of the first settlers in Europe, are of opinion that this strigil and the various jade implements found in the Swiss lake-dwellings, are relics of this Western migration from the primitive cradle of the Aryan race on the plateaus of Central Asia. The implements could only have come from the East, for the other sources of jade supply in New Zealand and America—since discovered—were altogether unknown in those primitive times. And this conclusion is supported by an imposing array of concurrent philological evidence, based upon the resemblances between the Aryan languages of Europe, so strangely akin to each other, and the ancient dialects of India and Persia. But plausible as this argument looks, the more probable explanation is that the inhabitants of Europe obtained the material which they laboriously fashioned into tools from the East, according to a system of barter similar to that which still exists amongst tribes more rude and savage than the Swiss lake-dwellers. Numerous facts of a like tendency are on record, such as the finding in the mounds of the Mississippi valley, side by side, obsidian from Mexico and mica from the Alleghanies, and in the mounds around the great northern lakes large tropical shells two thousand miles from their native habitat. The ancient inhabitants of China and India found at a very early period that they possessed in their jade rocks a very valuable material, in exchange for which they could get what they wanted from the Western races; while these Western races had at least one article which they could barter for the much-prized jade implements, viz. linen cloth, the weaving of which was practised in the oldest settlements, hanks of unspun flax and thread, nets and cloth of the same material having been found not unfrequently in the lake dwellings.
What an interesting glimpse into the far-off past does this link of connection between the East and the West give us! It indicates a degree of civilisation which we are not accustomed to associate with these primeval times. Archæologists are of opinion that the race who inhabited Central Europe during the earlier part of the stone age were akin to the modern Laplanders. The people of the lake dwellings, however, and especially those who used jade implements, who replaced them, were a superior and more civilised race. The evidence of the articles which they used, with the exception of jade itself, points not to an Asiatic origin, but rather to a connection with the shores on both sides of the Mediterranean. When they migrated northwards they brought with them the flax and the cereals of Egypt, and introduced with them the southern weeds which grew among these cultivated plants. The seeds of the catch-fly of Crete, which does not grow in Switzerland or Germany, have been found among the relics of the earliest of the lake dwellings; while the familiar corn blue-bottle of our autumn fields was first brought from its native Sicily by this lacustrine people in whose cultivated fields it grew as a weed, and by them spread over all Western and Northern Europe. Such are the interesting associations and profound problems connected with the material of the martyr weights. And it is unique in this respect, that it meets us as far back as the first traces of neolithic man in Central Europe—nay, farther back still, in the palæolithic flints found in the caves near Mentone; and that it is still used in the countries where it is found for a great variety of useful and ornamental purposes, idols being carved out of it, and altars adorned with its semi-transparent olive-green slabs. The inhabitants of the South Sea Islands until recently used it for their stone implements in the same way that the ancient lake dwellers did; and the Mogul emperors of Delhi set such a high value upon it on account of its superstitious virtues that they had it cut, jewelled, and enamelled into the most exquisite forms.
In Rome the martyr weights, as relics of the stone age, afford a curious example of a very primitive epoch projecting far into a highly-civilised one. Stone weights continued in use long after bronze and iron implements were constructed, on account of the sacred associations connected with them. Weights and measures were regarded by the Romans as invested with a peculiar religious significance; the stone of which the weights were composed was called from that circumstance, or because of the occult qualities attributed to it, lapis divinus; and therefore there was a deep-seated prejudice, which reached down to the days of the highest splendour of the Empire, against the introduction of a new substance. This was the case with all articles used in religious ceremonies. As late as the period of St. Paul's residence in Rome, and at the time of the first persecution of the Christians, ancient pagan rites were celebrated in the Forum, in which the use of metal was forbidden; and only stone hatchets could be employed in slaughtering animals, and only earthen vessels used in carrying the significant parts of the sacrifices into the temples. Treaties were also ratified by striking the victim offered on the occasion with a flint hatchet. The ancient Egyptians, although using iron and bronze for other objects, invariably used stone knives in preparing bodies for the process of embalming. The sacrifices which the Mexicans offered to their idols at the time of the Spanish conquest were cut up by means of knives of obsidian, which they obtained from the lavas of their volcanoes. In the Bible we have several traces of the same universal custom. The Jews seem to have performed the rite of circumcision with flint implements, for we read in Exodus that Zipporah, the wife of Moses, took a sharp stone for that purpose; and the phrase translated "sharp knives" in Joshua v. 2—"At that time the Lord said unto Joshua, Make thee sharp knives, and circumcise again the children of Israel the second time"—should be translated, as in the marginal reference, knives of flint. To the same ancient widespread habit may doubtless be referred the prohibition, mentioned in Exodus and Deuteronomy, against making an altar in any special place where God recorded His name, of hewn stone, or polluting it by lifting up any iron tool upon it. So strong is the conservative instinct in religion that to this very day the enlightened Brahmin of India will not use ordinary fire for sacred purposes, will not procure a fresh spark even from flint and steel, but reverts to, or rather continues the primitive way of obtaining it by friction with a wooden drill. Everywhere innovations in religious worship are resisted with more or less reason or prejudice. The instinct is universal, and has its good and its evil side.
CHAPTER IX
ST. ONOFRIO AND TASSO
One of the most romantic shrines of pilgrimage in Rome is the church of St. Onofrio. It is situated in the Trastevere, that portion of the city beyond the Tiber whose inhabitants boast of their pure descent from the ancient Romans. A steep ascent on the slope of the Janiculum, through a somewhat squalid but picturesque street, and terminating in a series of broad steps, leads up to it from the Porta di San Spirito, not far from the Vatican. The ground here is open and stretches away, free from buildings, to the walls of the city. The church has a simple old-fashioned appearance; its roof, walls, and small campanile are painted with the rusty gold of lichens that have sprung from the kisses of four centuries of rain and sun. It was erected in the reign of Pope Eugenius IV. by Nicolo da Forca Palena, an ancestor of that Conte di Palena who was a great friend of Torquato Tasso at Naples. It was dedicated to the Egyptian hermit Honuphrius, who for sixty years lived in a cave in the desert of Thebes, without seeing a human being or speaking a word, consorting with birds and beasts, and living upon roots and wild herbs. A subtle harmony is felt between the history of the hermit and the character of this building raised in his honour. A spot more drowsy and secluded, more steeped in the dreams of the older ages, is not to be found in the whole city. In front of the church there is a long, narrow portico, supported by eight antique columns of the simplest construction, in all likelihood borrowed from some old pagan temple. Under this portico is a beautiful fresco of the Madonna and Child by Domenichino. To the right are three lunettes, which contain paintings by the same great master, representing the Baptism, Temptation, and Flagellation of St. Jerome. On the left of the arcade are portraits of the most prominent saints of the Hieronomyte order. Exposed to the weather at first, these invaluable frescoes had faded into mere spectres of pictures; but they are now protected from further injury by glass.
