Part 14

In former ages it was different: forebodings and predictions found universal credence. The ancient forms of divination, however, had fallen somewhat into disrepute at the beginning of our era, like the rest of the Greco-Roman religion. It was no longer thought that the eagerness or reluctance with which the sacred hens ate their paste, or the direction of the flight of the birds indicated coming success or disaster. Abandoned, the Hellenic oracles were silent. Then appeared astrology, surrounded with all the prestige of an exact science, and based upon the experience of many centuries. It promised to ascertain the {163} occurrences of any one's life with as much precision as the date of an eclipse. The world was drawn towards it by an irresistible attraction. Astrology did away with, and gradually relegated to oblivion, all the ancient methods that had been devised to solve the enigmas of the future. Haruspicy and the augural art were abandoned, and not even the ancient fame of the oracles could save them from falling into irretrievable desuetude. This great chimera changed religion as well as divination, its spirit penetrated everything. And truly, if, as some scholars still hold, the main feature of science is the ability to predict,[2] no branch of learning could compare with this one, nor escape its influence.

The success of astrology was connected with that of the Oriental religions, which lent it their support, as it in turn helped them. We have seen how it forced itself upon Semitic paganism, how it transformed Persian Mazdaism and even subdued the arrogance of the Egyptian sacerdotal caste.[3] Certain mystical treatises ascribed to the old Pharaoh Nechepso and his confidant, the priest Petosiris, nebulous and abstruse works that became, one might say, the Bible of the new belief in the power of the stars, were translated into Greek, undoubtedly in Alexandria, about the year 150 before our era.[4] About the same time the Chaldean genethlialogy began to spread in Italy, with regard to which Berosus, a priest of the god Baal, who came to Babylon from the island of Cos, had previously succeeded in arousing the curiosity of the Greeks. In 139 a prætor expelled the "Chaldaei" from Rome, together with the Jews. But all the adherents of the Syrian goddess, of whom there was quite a number in the Occident, were patrons and defenders of these Oriental {164} prophets, and police measures were no more successful in stopping the diffusion of their doctrines, than in the case of the Asiatic mysteries. In the time of Pompey, the senator Nigidius Figulus, who was an ardent occultist, expounded the barbarian uranography in Latin. But the scholar whose authority contributed most to the final acceptance of sidereal divination was a Syrian philosopher of encyclopedic knowledge, Posidonius of Apamea, the teacher of Cicero.[5] The works of that erudite and religious writer influenced the development of the entire Roman theology more than anything else.

Under the empire, while the Semitic Baals and Mithra were triumphing, astrology manifested its power everywhere. During that period everybody bowed to it. The Cæsars became its fervent devotees, frequently at the expense of the ancient cults. Tiberius neglected the gods because he believed only in fatalism,[6] and Otho, blindly confiding in the Oriental seer, marched against Vitellius in spite of the baneful presages that affrighted his official clergy.[7] The most earnest scholars, Ptolemy under the Antonines for instance, expounded the principles of that pseudo-science, and the very best minds received them. In fact, scarcely anybody made a distinction between astronomy and its illegitimate sister. Literature took up this new and difficult subject, and, as early as the time of Augustus or Tiberius, Manilius, inspired by the sidereal fatalism, endeavored to make poetry of that dry "mathematics," as Lucretius, his forerunner, had done with the Epicurean atomism. Even art looked there for inspiration and depicted the stellar deities. At Rome and in the provinces architects erected sumptuous _septizonia_ in the likeness of {165} the seven spheres in which the planets that rule our destinies move.[8] This Asiatic divination was first aristocratic[9]--because the obtaining of an exact horoscope was a complicated matter, and consultations were expensive--but it promptly became popular, especially in the urban centers where Oriental slaves gathered in large numbers. The learned genethlialogers of the observatories had unlicensed colleagues, who told fortunes at street-crossings or in barnyards. Even common epitaphs, which Rossi styles "the scum of inscriptions," have retained traces of that belief. The custom arose of stating in epitaphs the exact length of a life to the very hour, for the moment of birth determined that of death:

_Nascentes morimur, finisque ab origine pendet._[10]

Soon neither important nor small matters were undertaken without consulting the astrologer. His previsions were sought not only in regard to great public events like the conduct of a war, the founding of a city, or the accession of a ruler, not only in case of a marriage, a journey, or a change of domicile; but the most trifling acts of every-day life were gravely submitted to his sagacity. People would no longer take a bath, go to the barber, change their clothes or manicure their fingernails, without first awaiting the propitious moment.[11] The collections of "initiatives" ([Greek: katarchai]) that have come to us contain questions that make us smile: Will a son who is about to be born have a big nose? Will a girl just coming into this world have gallant adventures?[12] And certain precepts sound almost like burlesques: he who gets his hair cut while {166} the moon is in her increase will become bald--evidently by analogy.[13]

The entire existence of states and individuals, down to the slightest incidents, was thought to depend on the stars. The absolute control they were supposed to exercise over everybody's daily condition, even modified the language in every-day use and left traces in almost all idioms derived from the Latin. If we speak of a martial, or a jovial character, or a lunatic, we are unconsciously admitting the existence, in these heavenly bodies (Mars, Jupiter, Luna) of their ancient qualities.

It must be acknowledged, however, that the Grecian spirit tried to combat the folly that was taking hold of the world, and from the time of its propagation astrology found opponents among the philosophers. The most subtle of these adversaries was the probabilist Carneades, in the second century before our era. The topical arguments which he advanced, were taken up, reproduced, and developed in a thousand ways by later polemicists. For instance, Were all the men that perish together in a battle, born at the same moment, because they had the same fate? Or, on the other hand, do we not observe that twins, born at the same time, have the most unlike characters and the most different fortunes?

But dialectics are an accomplishment in which the Greeks ever excelled, and the defenders of astrology found a reply to every objection. They endeavored especially to establish firmly the truths of observation, upon which rested the entire learned structure of their art: the influence of the stars over the phenomena of nature and the characters of individuals. Can it be {167} denied, they said, that the sun causes vegetation to appear and to perish, and that it puts animals _en rut_ or plunges them into lethargic sleep? Does not the movement of the tide depend on the course of the moon? Is not the rising of certain constellations accompanied every year by storms? And are not the physical and moral qualities of the different races manifestly determined by the climate in which they live? The action of the sky on the earth is undeniable, and, the sidereal influences once admitted, all previsions based on them are legitimate. As soon as the first principle is admitted, all corollaries are logically derived from it.

This way of reasoning was universally considered irrefutable. Before the advent of Christianity, which especially opposed it because of its idolatrous character, astrology had scarcely any adversaries except those who denied the possibility of science altogether, namely, the neo-Academicians, who held that man could not attain certainty, and such radical sceptics as Sextus Empiricus. Upheld by the Stoics, however, who with very few exceptions were in favor of astrology, it can be maintained that it emerged triumphant from the first assaults directed against it. The only result of the objections raised to it was to modify some of its theories. Later, the general weakening of the spirit of criticism assured astrology an almost uncontested domination. Its adversaries did not renew their polemics; they limited themselves to the repetition of arguments that had been opposed, if not refuted, a hundred times, and consequently seemed worn out. At the court of the Severi any one who should have denied the influence of the planets upon the events of this world {168} would have been considered more preposterous than he who would admit it to-day.

But, you will say, if the theorists did not succeed in proving the doctrinal falsity of astrology, experience should have shown its worthlessness. Errors must have occurred frequently and must have been followed by cruel disillusionment. Having lost a child at the age of four for whom a brilliant future had been predicted, the parents stigmatized in the epitaph the "lying mathematician whose great renown deluded them."[14] Nobody thought of denying the possibility of such errors. Manuscripts have been preserved, wherein the makers of horoscopes themselves candidly and learnedly explain how they were mistaken in such and such a case, because they had not taken into account some one of the data of the problem.[15] Manilius, in spite of his unlimited confidence in the power of reason, hesitated at the complexity of an immense task that seemed to exceed the capacity of human intelligence,[16] and in the second century, Vettius Valens bitterly denounced the contemptible bunglers who claimed to be prophets, without having had the long training necessary, and who thereby cast odium and ridicule upon astrology, in the name of which they pretended to operate.[17] It must be remembered that astrology, like medicine, was not only a science ([Greek: epistêmê]), but also an art ([Greek: technê]). This comparison, which sounds irreverent to-day, was a flattering one in the eyes of the ancients.[18] To observe the sky was as delicate a task as to observe the human body; to cast the horoscope of a newly born child, just as perilous as to make a diagnosis, and to interpret the cosmic symptoms just as hard as to {169} interpret those of our organism. In both instances the elements were complex and the chances of error infinite. All the examples of patients dying in spite of the physician, or on account of him, will never keep a person who is tortured by physical pain from appealing to him for help; and similarly those whose souls were troubled with ambition or fear turned to the astrologer for some remedy for the moral fever tormenting them. The calculator, who claimed to determine the moment of death, and the medical practitioner who claimed to avert it received the anxious patronage of people worried by this formidable issue. Furthermore, just as marvelous cures were reported, striking predictions were called to mind or, if need were, invented. The diviner had, as a rule, only a restricted number of possibilities to deal with, and the calculus of probabilities shows that he must have succeeded sometimes. Mathematics, which he invoked, was in his favor after all, and chance frequently corrected mischance. Moreover, did not the man who had a well-frequented consulting-office, possess a thousand means, if he was clever, of placing all the chances on his side, in the hazardous profession he followed, and of reading in the stars anything he thought expedient? He observed the earth rather than the sky, and took care not to fall into a well.

However, what helped most to make astrology invulnerable to the blows of reason and of common sense, was the fact that in reality, the apparent rigor of its calculus and its theorems notwithstanding, it was not a science but a faith. We mean not only that {170} it implied belief in postulates that could not be proved--the same thing might be said of almost all of our poor human knowledge, and even our systems of physics and cosmology in the last analysis are based upon hypotheses--but that astrology was born and reared in the temples of Chaldea and Egypt.[19] Even in the Occident it never forgot its sacerdotal origin and never more than half freed itself from religion, whose offspring it was. Here lies the connection between astrology and the Oriental religions, and I wish to draw the reader's special attention to this point.

The Greek works and treatises on astrology that have come down to us reveal this essential feature only very imperfectly. The Byzantines stripped this pseudo-science, always regarded suspiciously by the church, of everything that savored of paganism. Their process of purification can, in some instances, be traced from manuscript to manuscript.[20] If they retained the name of some god or hero of mythology, the only way they dared to write it was by cryptography. They have especially preserved purely didactic treatises, the most perfect type of which is Ptolemy's Tetrabiblos which has been constantly quoted and commented upon; and they have reproduced almost exclusively expurgated texts, in which the principles of various doctrines are drily summarized. During the classic age works of a different character were commonly read. Many "Chaldeans" interspersed their cosmological calculations and theories with moral considerations and mystical speculations. In the first part of a work that he names "Vision," ([Greek: Horasis]) Critodemus, in prophetic language, represents the truths he reveals {171} as a secure harbor of refuge from the storms of this world, and he promises his readers to raise them to the rank of immortals.[21] Vettius Valens, a contemporary of Marcus Aurelius, implored them in solemn terms, not to divulge to the ignorant and impious the arcana he was about to acquaint them with.[22] The astrologers liked to assume the appearance of incorruptible and holy priests and to consider their calling a sacerdotal one.[23] In fact, the two ministries sometimes combined: A dignitary of the Mithraic clergy called himself _studiosus astrologiae_[24] in his epitaph, and a member of a prominent family of Phrygian prelates celebrated in verse the science of divination which enabled him to issue a number of infallible predictions.[25]

The sacred character of astrology revealed itself in some passages that escaped the orthodox censure and in the tone some of its followers assumed, but we must go further and show that astrology was religious in its principles as well as in its conclusions, the debt it owed to mathematics and observation notwithstanding.

The fundamental dogma of astrology, as conceived by the Greeks, was that of universal solidarity. The world is a vast organism, all the parts of which are connected through an unceasing exchange of molecules of effluvia. The stars, inexhaustible generators of energy, constantly act upon the earth and man--upon man, the epitome of all nature, a "microcosm" whose every element corresponds to some part of the starry sky. This was, in a few words, the theory formulated by the Stoic disciples of the Chaldeans;[26] but if we divest it of all the philosophic garments with which it has been adorned, what do we find? The idea of {172} sympathy, a belief as old as human society! The savage peoples also established mysterious relations between all bodies and all the beings that inhabit the earth and the heavens, and which to them were animated with a life of their own endowed with latent power, but we shall speak of this later on, when taking up the subject of magic. Even before the propagation of the Oriental religions, popular superstition in Italy and Greece attributed a number of odd actions to the sun, the moon, and the constellations as well.[27]

The Chaldaei, however, claimed a predominant power for the stars. In fact, they were regarded as gods _par excellence_ by the religion of the ancient Chaldeans in its beginnings. The sidereal religion of Babylon concentrated deity, one might say, in the luminous moving bodies at the expense of other natural objects, such as stones, plants, animals, which the primitive Semitic faith considered equally divine. The stars always retained this character, even at Rome. They were not, as to us, infinitely distant bodies moving in space according to the inflexible laws of mechanics, and whose chemical composition may be determined. To the Latins as to the Orientals, they were propitious or baleful deities, whose ever-changing relations determined the events of this world.

The sky, whose unfathomable depth had not yet been perceived, was peopled with heroes and monsters of contrary passions, and the struggle above had an immediate echo upon earth. By what principle have such a quality and so great an influence been attributed to the stars? Is it for reasons derived from their apparent motion and known through observation or experience? Sometimes. Saturn made people {173} apathetic and irresolute, because it moved most slowly of all the planets.[28] But in most instances purely mythological reasons inspired the precepts of astrology. The seven planets were associated with certain deities, Mars, Venus, or Mercury, whose character and history are known to all. It is sufficient simply to pronounce their names to call to mind certain personalities that may be expected to act according to their natures, in every instance. It was natural for Venus to favor lovers, and for Mercury to assure the success of business transactions and dishonest deals. The same applies to the constellations, with which a number of legends are connected: "catasterism" or translation into the stars, became the natural conclusion of a great many tales. The heroes of mythology, or even those of human society, continued to live in the sky in the form of brilliant stars. There Perseus again met Andromeda, and the Centaur Chiron, who is none other than Sagittarius, was on terms of good fellowship with the Dioscuri.

These constellations, then, assumed to a certain extent the good and the bad qualities of the mythical or historical beings that had been transferred upon them. For instance, the serpent, which shines near the northern pole, was the author of medical cures, because it was the animal sacred to Æsculapius.[29]

The religious foundation of the rules of astrology, however, can not always be recognized. Sometimes it is entirely forgotten, and in such cases the rules assume the appearance of axioms, or of laws based upon long observation of celestial phenomena. Here we have a simple aspect of science. The process of {174} assimilation with the gods and catasterism were known in the Orient long before they were practiced in Greece.

The traditional outlines that we reproduce on our celestial maps are the fossil remains of a luxuriant mythological vegetation, and besides our classic sphere the ancients knew another, the "barbarian" sphere, peopled with a world of fantastic persons and animals. These sidereal monsters, to whom powerful qualities were ascribed, were likewise the remnants of a multitude of forgotten beliefs. Zoolatry was abandoned in the temples, but people continued to regard as divine the lion, the bull, the bear, and the fishes, which the Oriental imagination had seen in the starry vault. Old totems of the Semitic tribes or of the Egyptian divisions lived again, transformed into constellations. Heterogeneous elements, taken from all the religions of the Orient, were combined in the uranography of the ancients, and in the power ascribed to the phantoms that it evoked, vibrates in the indistinct echo of ancient devotions that are often completely unknown to us.[30]

Astrology, then, was religious in its origin and in its principles. It was religious also in its close relation to the Oriental religions, especially those of the Syrian Baals and of Mithra; finally, it was religious in the effects that it produced. I do not mean the effects expected from a constellation in any particular instance: as for example the power to evoke the gods that were subject to their domination.[31] But I have in mind the general influence those doctrines exercised upon Roman paganism.

When the Olympian gods were incorporated among the stars, when Saturn and Jupiter became planets and {175} the celestial virgin a sign of the zodiac, they assumed a character very different from the one they had originally possessed. It has been shown[32] how, in Syria, the idea of an infinite repetition of cycles of years according to which the celestial revolutions took place, led to the conception of divine eternity, how the theory of a fatal domination of the stars over the earth brought about that of the omnipotence of the "lord of the heavens," and how the introduction of a universal religion was the necessary result of the belief that the stars exerted an influence upon the peoples of every climate. The logic of all these consequences of the principles of astrology was plain to the Latin as well as to the Semitic races, and caused a rapid transformation of the ancient idolatry. As in Syria, the sun, which the astrologers called the leader of the planetary choir, "who is established as king and leader of the whole world,"[33] necessarily became the highest power of the Roman pantheon.

Astrology also modified theology, by introducing into this pantheon a great number of new gods, some of whom were singularly abstract. Thereafter man worshiped the constellations of the firmament, particularly the twelve signs of the zodiac, every one of which had its mythologic legend; the sky (_Caelus_) itself, because it was considered the first cause, and was sometimes confused with the supreme being; the four elements, the antithesis and perpetual transmutations of which produced all tangible phenomena, and which were often symbolized by a group of animals ready to devour each other;[34] finally, time and its subdivisions.[35]

The calendars were religious before they were secular; their purpose was not, primarily, to record fleeting {176} time, but to observe the recurrence of propitious or inauspicious dates separated by periodic intervals. It is a matter of experience that the return of certain moments is associated with the appearance of certain phenomena; they have, therefore, a special efficacy, and are endowed with a sacred character. By determining periods with mathematical exactness, astrology continued to see in them "a divine power,"[36] to use Zeno's term. Time, that regulates the course of the stars and the transubstantiation of the elements, was conceived of as the master of the gods and the primordial principle, and was likened to destiny. Each part of its infinite duration brought with it some propitious or evil movement of the sky that was anxiously observed, and transformed the ever modified universe. The centuries, the years and the seasons, placed into relation with the four winds and the four cardinal points, the twelve months connected with the zodiac, the day and the night, the twelve hours, all were personified and deified, as the authors of every change in the universe. The allegorical figures contrived for these abstractions by astrological paganism did not even perish with it.[37] The symbolism it had disseminated outlived it, and until the Middle Ages these pictures of fallen gods were reproduced indefinitely in sculpture, mosaics, and in Christian miniatures.[38]
