No long experience was needed to discover the fact that the majority of solar eclipses were followed some fourteen days and a half after by an eclipse of the moon; but they were unable to take sufficient advantage of this experience to predict with certainty the instant of a future eclipse of the sun, although they had been so struck with the connection of the two phenomena as to believe that they were in a position to announce it approximately.* They were frequently deceived in their predictions, and more than one eclipse which they had promised did not take place at the time expected:** but their successful prognostications were sufficiently frequent to console them for their failures, and to maintain the respect of the people and the rulers for their knowledge. Their years were vague years of three hundred and sixty days. The twelve equal months of which they were composed bore names which were borrowed, on the one hand, from events in civil life, such as “Simanu,” from the making of brick, and “Addaru,” from the sowing of seed, and, on the other, from mythological occurrences whose origin is still obscure, such as “Nisanu,” from the altar of Ea, and “Elul,” from a message of Ishtar. The adjustment of this year to astronomical demands was roughly carried out by the addition of a month every six years, which was called a second Adar, Blul, or Nisan, according to the place in which it was intercalated.
* Tannery is of opinion that the Chaldæans must have
predicted eclipses of the sun by means of the period of two
hundred and twenty-three lunations, and shows by what a
simple means they could have arrived at it.
** An astronomer mentions, in the time of Assurbanipal, that
on the 28th, 29th, and 30th of the month he prepared for the
observation of an eclipse; but the sun continued brilliant,
and the eclipse did not take place.
The neglect of the hours and minutes in their calculation of the length of the year became with them, as with the Egyptians, a source of serious embarrassment, and we are still ignorant as to the means employed to meet the difficulty. The months had relations to the signs of the zodiac, and the days composing them were made up of twelve double hours each. The Chaldæns had invented two instruments, both of them of a simple character, to measure time—the clepsydra and the solar clock, the latter of which in later times became the source of the Greek “polos.” The sun-dial served to determine a number of simple facts which were indispensable in astronomical calculations, such as the four cardinal points, the meridian of the place, the solstitial and equinoctial epochs, and the elevation of the pole at the position of observation. The construction of the sundial and clepsydra, if not of the polos also, is doubtless to be referred back to a very ancient date, but none of the texts already brought to light makes mention of the employment of these instruments.*
* Herodotus (ii. 109) formally attributes the invention of
the sun-dial and polos to the Babylonians. The “polos” was a
solar clock. It consisted of a concave hemisphere with a
style rising from its centre: the shadow of the style
described every day an arc of a circle parallel to the
equator, and the daily parallels were divided into twelve or
twenty-four equal parts. Smith discovered, in the palace of
Sennacherib at Koyunjik, a portion of an astrolabe, which is
now in the British Museum.
All these discoveries, which constitute in our eyes the scientific patrimony of the Chaldæans, were regarded by themselves as the least important results of their investigations. Did they not know, thanks to these investigations, that the stars shone for other purposes than to lighten up the nights—to rule, in fact, the destinies of men and kings, and, in ruling that of kings, to determine the fortune of empires? Their earliest astronomers, by their assiduous contemplation of the nightly heavens, had come to the conclusion that the vicissitudes of the heavenly bodies were in fixed relations with mundane phenomena and events. If Mercury, for instance, displayed an unusual brilliancy at his rising, and his disk appeared as a two-edged sword, riches and abundance, due to the position of the luminous halo which surrounded him, would be scattered over Chaldæa, while discords would cease therein, and justice would triumph over iniquity. The first observer who was struck by this coincidence noted it down; his successors confirmed his observations, and at length deduced, in the process of the years, from their accumulated knowledge, a general law. Henceforward, each time that Mercury assumed the same aspect it was of favourable augury, and kings and their subjects became the recipients of his bounty. As long as he maintained this appearance no foreign ruler could install himself in Chaldæa, tyranny would be divided against itself, equity would prevail, and a strong monarch bear sway; while the landholders and the king would be confirmed in their privileges, and obedience, together with tranquillity, would rule everywhere in the land. The number of these observations increased to such a degree that it was found necessary to classify them methodically to avoid confusion. Tables of them were drawn up, in which the reader could see at one and the same moment the aspect of the heavens on such and such a night and hour, and the corresponding events either then happening, or about to happen, in Chaldæan, Syria, or some foreign land. If, for instance, the moon displayed the same appearance on the 1st and 27th of the month, Elam was threatened; but “if the sun, at his setting, appears double his usual size, with three groups of bluish rays, the King of Chaldæa is ruined.” To the indications of the heavenly bodies, the Chaldæans added the portents which could be deduced from atmospheric phenomena: if it thundered on the 27th of Tammuz, the wheat-harvest would be excellent and the produce of the ears magnificent; but if this, should occur six days later, that is, on the 2nd of Abu, floods and rains were to be apprehended in a short time, together with the death of the king and the division of his empire. It was not for nothing that the sun and moon surrounded themselves in the evening with blood-red vapours or veiled themselves in dark clouds; that they grew suddenly pale or red after having been intensely bright; that unexpected fires blazed out on the confines of the air, and that on certain nights the stars seemed to have become detached from the firmament and to be falling upon the earth. These prodigies were so many warnings granted by the gods to the people and their kings before great crises in human affairs: the astronomer investigated and interpreted them, and his predictions had a greater influence than we are prepared to believe upon the fortunes of individuals and even of states. The rulers consulted and imposed upon the astronomers the duty of selecting the most favourable moment for the execution of the projects they had in view. From an early date each temple contained a library of astrological writings, where the people might find, drawn up as in a. code, the signs which bore upon their destinies. One of these libraries, consisting of not less than seventy clay tablets, is considered to have been first drawn up in the reign of Sargon of Agadê, but to have been so modified and enriched with new examples from time to time that the original is well-nigh lost. This was the classical work on the subject in the VIIth century before our era, and the astronomers-royal, to whom applications were accustomed to be made to explain a natural phenomenon or a prodigy, drew their answers ready-made from it. Astronomy, as thus understood, was not merely the queen of sciences, it was the mistress of the world: taught secretly in the temples, its adepts—at least, those who had passed through the regular curriculum of study which it required—became almost a distinct class in society. The occupation was a lucrative one, and its accomplished professors had numerous rivals whose educational antecedents were unknown, but who excited the envy of the experts in their trading upon the credulity of the people. These quacks went about the country drawing up horoscopes, and arranging schemes of birthday prognostications, of which the majority were without any authentic warranty. The law sometimes took note of the fact that they were competing with the official experts, and interfered with their business: but if they happened to be exiled from one city, they found some neighbouring one ready to receive them.
Chaldæa abounded with soothsayers and necromancers no less than with astrologers; she possessed no real school of medicine, such as we find in Egypt, in which were taught rational methods of diagnosing maladies and of curing them by the use of simples. The Chaldaeans were content to confide the care of their bodies to sorcerers and exorcists, who were experts in the art of casting out demons and spirits, whose presence in a living being brought about those disorders to which humanity is prone. The facial expression of the patient during the crisis, the words which escaped from him in delirium, were, for these clever individuals, so many signs revealing the nature and sometimes the name of the enemy to be combated—the Fever-god, the Plague-god, the Headache-god. Consultations and medical treatment were, therefore, religious offices, in which were involved purifications, offerings, and a whole ritual of mysterious words and gestures. The magician lighted a fire of herbs and sweet-smelling plants in front of his patient, and the clear flame arising from this put the spectres to flight and dispelled the malign influences, a prayer describing the enchantments and their effects being afterwards recited. “The baleful imprecation like a demon has fallen upon a man;—wail and pain have fallen upon him,—direful wail has fallen upon him,—the baleful imprecation, the spell, the pains in the head!—This man, the baleful imprecation slaughters him like a sheep,—for his god has quitted his body—his goddess has withdrawn herself in displeasure from him,—a wail of pain has spread itself as a garment upon him and has overtaken him!” The harm done by the magician, though terrible, could be repaired by the gods, and Merodach was moved to compassion betimes. Merodach cast his eyes on the patient, Merodach entered into the house of his father Ea, saying: “My father, the baleful curse has fallen like a demon upon the man!” Twice he thus speaks, and then adds: “What this man ought to do, I know not; how shall he be healed?” Ea replies to his son Merodach: “My son, what is there that I could add to thy knowledge?—Merodach, what is there that I could add to thy knowledge?—That which I know, thou knowest it:—go then, my son, Merodach,—lead him to the house of purification of the god who prepares remedies,—and break the spell that is upon him, draw away the charm which is upon him,—the ill which afflicts his body,—which he suffers by reason of the curse of his father,—or the curse of his mother,—or the curse of his eldest brother,—or by the curse of a murderess who is unknown to the man.—The curse, may it be taken from him by the charm of Ea,—like a clove of garlic which is stripped skin by skin,—like a cluster of dates may it be cut off,—like a bunch of flowers may it be uprooted! The spell, may heaven avert it,—may the earth avert it!” The god himself deigned to point out the remedy: the sick man was to take a clove of garlic, some dates, and a stalk bearing flowers, and was to throw them into the fire, bit by bit, repeating appropriate prayers at each stage of the operation. “In like manner as this garlic is peeled and thrown into the fire,—and the burning flame consumes it,—as it will never be planted in the vegetable garden, it will never draw moisture from the pond or from the ditch,—its root will never again spread in the earth,—its stalk will not pierce the ground and behold the sun,—it will not serve as food for the gods or the king,—so may it remove the baleful curse, so may it loose the bond—of sickness, of sin, of shortcomings, of perversity, of crime!—The sickness which is in my body, in my flesh, in my muscles,—like this garlic may it be stripped off,—and may the burning flame consume it in this day;—may the spell of the sorcerer be cast out, that I may behold the light!” The ceremony could be prolonged at will: the sick person pulled to pieces the cluster of dates, the bunch of flowers, a fleece of wool, some goats’ hair, a skein of dyed thread, and a bean, which were all in turn consumed in the fire. At each stage of the operation he repeated the formula, introducing into it one or two expressions characterizing the nature of the particular offering; as, for instance, “the dates will no more hang from their stalks, the leaves of the branch will never again be united to the tree, the wool and the hair will never again lie on the back of the animal on which they grew, and will never be used for weaving garments.” The use of magical words was often accompanied by remedies, which were for the most part both grotesque and disgusting in their composition: they comprised bitter or stinking wood-shavings, raw meat, snake’s flesh, wine and oil, the whole reduced to a pulp, or made into a sort of pill and swallowed on the chance of its bringing relief. The Egyptian physicians employed similar compounds, to which they attributed wonderful effects, but they made use of them in exceptional circumstances only. The medical authorities in Chaldæa recommended them before all others, and their very strangeness reassured the patient as to their efficacy: they filled the possessing spirits with disgust, and became a means of relief owing to the invincible horror with which they inspired the persecuting demons. The Chaldæans were not, however, ignorant of the natural virtues of herbs, and at times made use of them; but they were not held in very high esteem, and the physicians preferred the prescriptions which pandered to the popular craving for the supernatural. Amulets further confirmed the effect produced by the recipes, and prevented the enemy, once cast out, from re-entering the body; these amulets were made of knots of cord, pierced shells, bronze or terra-cotta statuettes, and plaques fastened to the arms or worn round the neck. On each of the latter kind were roughly drawn the most terrible images that they could conceive, a shortened incantation was scrawled on its surface, or it was covered with extraordinary characters, which when the spirits perceived they at once took flight, and the possessor of the talisman escaped the threatened illness.
However laughable, and at the same time deplorable, this hopeless medley of exact knowledge and gross superstition may appear to us at the present day, it was the means of bringing a prosperity to the cities of Chaldæa which no amount of actual science would ever have produced. The neighbouring barbaric peoples were imbued with the same ideas as the Chaldæns regarding the constitution of the world and the nature of the laws which governed it. They lived likewise in perpetual fear of those invisible beings whose changeable and arbitrary will actuated all visible phenomena; they attributed all the reverses and misfortunes which overtook them to the direct action of these malevolent beings; they believed firmly in the influence of stars on the course of events; they were constantly on the look out for prodigies, and were greatly alarmed by them, since they had no certain knowledge of the number and nature of their enemies, and the means they had invented for protecting themselves from them or of overcoming them too often proved inefficient. In the eyes of these barbarians, the Chaldeans seemed to be possessed of the very powers which they themselves lacked. The magicians of Chaldæa had forced the demons to obey them and to unmask themselves before them; they read with ease in the heavens the present and future of men and nations; they interpreted the will of the immortals in its smallest manifestations, and with them this faculty was not a limited and ephemeral power, quickly exhausted by use: the rites and formulas known to them enabled them to exercise it freely at all times, in all places, alike upon the most exalted of the gods and the most dreaded of mortals, without its ever becoming weakened.
