History of astrology
The History of astrology encompasses a great span of human history and many cultures. The belief in a connection between the heavenly bodies and the lives of people has also played an important part in human history. See also the main article on Astrology.
Overview
For the overwhelming bulk of human history, astronomy and astrology were regarded as one and the same subject, with a distinction being made between "natural astrology" (the study of the motions of the heavenly bodies, timing of eclipses, etc.) and "judicial astrology" (the study of the supposed correlations between the positions of various celestial objects and the affairs of human beings).
Isidore of Seville (d. 636) was one of the first to distinguish between astronomy and astrology. However, astronomy did not begin to be separated from astrology until the 16th century, when, with the system of Copernicus, the conviction that the earth itself is one of the heavenly bodies was finally established.
The study of astrology and the belief in it, as part of astronomy, is found in a developed form among the ancient Babylonians; and directly or indirectly through the Babylonians, it spread to other nations. It came to Greece about the middle of the 4th century B.C., and reached Rome before the opening of the Christian era.
In India and China, astronomy and astrology are largely reflections of Greek theories and speculations; and similarly with the introduction of Greek culture into Egypt, both astronomy and astrology were actively cultivated in the region of the Nile during the Hellenistic and Roman periods. Astrology was further developed by the Arabs from the 7th to the 13th century, and in the Europe of the 14th and 15th centuries astrologers were dominating influences at court.
Even up to the present day, some peeople of intellectual eminence believe that astrology has a foundation of truth, just as there are still believers in chiromancy or other forms of divination.
There is an obvious tendency, however, for astrology to be employed, like palmistry, as a means of imposing on the ignorant and credulous. The generally established belief of the scientific community is that astrology is either mere superstition or absolute imposture, and that its vogue is due either to willful deception or to fatuous, unscientific gullibility.
On the other hand though, the people who do believe in astrology or divination accept that there are certain aspects of reality that cannot be explained through the process of logic. They regard this aspect of reality as something beyond comprehension and scientific understanding and as something that can only be felt, possibly through the sixth sense. They view the scientific community as ignorant because unable to accept anything that is not explained; this is more an acceptance of human limitations, and embrace of that which can only be felt and not understood. Since these senses have not been explained in a scientific sense, they are discarded as nonsense. The people that believe these mystical aspects of life trust these to be the true underlining principles of reality and deplore the scientific community for its simplistic materialistic view of reality that tends to strip the world of any spiritual meaning.
Western astrology's Babylonian origins
The history of western astrology can now be traced back to ancient Babylonia, and indeed to the earliest phases of Babylonian history, e.g. to about 3000 B.C.
In Babylonia as well as in Assyria as a direct offshoot of Babylonian culture (or as we might also term it "Euphratean" culture), astrology takes its place in the official cult as one of the two chief means at the disposal of the priests (who were called bare or "inspectors") for ascertaining the will and intention of the gods, the other being through the inspection of the liver of the sacrificial animal (see omen).
Just as this latter method of divination rested on a well-defined theory - to wit, that the liver was the seat of the soul of the animal and that the deity in accepting the sacrifice identified himself with the animal, whose "soul" was thus placed in complete accord with that of the god and therefore reflected the mind and will of the god - so astrology is sometimes purported to be based on a theory of divine government of the world.
Starting with the indisputable fact that man's life and happiness are largely dependent upon phenomena in the heavens, that the fertility of the soil is dependent upon the sun shining in the heavens as well as upon the rains that come from heaven; and that, on the other hand, the mischief and damage done by storms and floods (both of which the Euphratean Valley was almost regularly subject to), were to be traced likewise to the heavens - the conclusion was drawn that all the great gods had their seats in the heavens.
In that early age of culture known as the "nomadic" stage, which under normal conditions precedes the "agricultural" stage, the moon cult is even more prominent than sun worship, and with the moon and sun cults thus furnished by the "popular" faith, it was a natural step for the priests, who correspond to the "scientists" of a later day, to perfect a theory of a complete accord between phenomena observed in the heavens and occurrences on earth.
Babylonian astrology
Of the planets five were recognized - Jupiter, Venus, Saturn, Mercury and Mars - to name them in the order in which they appear in the older cuneiform literature; in later texts Mercury and Saturn change places.
These five planets were identified with the gods of the Babylonian pantheon as follows:
Jupiter with Marduk;
Venus with the goddess Ishtar,
Saturn with Ninurta (Ninib),
Mercury with Nabu (Nebo),
and Mars with Nergal.
The movements of the sun, moon and five planets were regarded as representing the activity of the five gods in question, together with the moon-god Sin and the sun-god Shamash, in preparing the occurrences on earth. If, therefore, one could correctly read and interpret the activity of these powers, one knew what the gods were aiming to bring about.
The Babylonian priests accordingly applied themselves to the task of perfecting a system of interpretation of the phenomena to be observed in the heavens, and it was natural that the system was extended from the moon, sun and five planets to the more prominent and recognizable fixed stars.
The interpretations themselves were based (as in the case of divination through the liver) chiefly on two factors:
On the recollection or on written records of what in the past had taken place when the phenomenon or phenomena in question had been observed, and
Association of ideas - involving sometimes merely a play upon words - in connection with the phenomenon or phenomena observed.
Thus, if on a certain occasion, the rise of the new moon in a cloudy sky was followed by victory over an enemy or by abundant rain, the sign in question was thus proved to be a favourable one and its recurrence would thenceforth be regarded as a good omen, though the prognostication would not necessarily be limited to the one or the other of those occurrences, but might be extended to apply to other circumstances.
On the other hand, the appearance of the new moon earlier than was expected was regarded as unfavourable - prognosticating in one case defeat, in another death among cattle, in a third bad crops - not necessarily because these events actually took place after such a phenomenon, but by an application of the general principle resting upon association of ideas whereby anything premature would suggest an unfavourable occurrence.
In this way a mass of traditional interpretation of all kinds of observed phenomena was gathered, and once gathered became a guide to the priests for all times. However, not all of these ideas are still used in astrology as it is usually practiced today.
Astrology in its earliest stage was marked by three characteristic limitations:
In the first place, the movements and position of the heavenly bodies point to such occurrences as are of public import and affect the general welfare.
The individual's interests are not in any way involved, and we must descend many centuries and pass beyond the confines of Babylonia and Assyria before we reach that phase which in medieval and modern astrology is almost exclusively dwelt upon - the individual horoscope.
In Babylonia and Assyria the cult centred largely and indeed almost exclusively in the public welfare and the person of the king, because upon his well-being and favour with the gods the fortunes of the country were dependant, in accordance with the ancient conception of kingship (see J. G. Frazer, The Early History of Kingship).
In the second place, the astronomical knowledge presupposed and accompanying early Babylonian astrology was, though essentially of an empirical character, limited and flawed.
The theory of the ecliptic as representing the course of the sun through the year, divided among twelve constellations with a measurement of 30° to each division, is of Babylonian origin, as has now been definitely proved; but it does not appear to have been perfected until after the fall of the Babylonian empire in 539 B.C.
Similarly, the other accomplishments of Babylonian astronomers, such as their system or rather systems of moon calculations and the drawing up of planetary tablets, belong to this late period, so that the golden age of Babylonian astronomy belongs not to the remote past, as was until recently supposed, but to the Seleucid period, i.e. after the advent of the Greeks in the Euphrates Valley.
From certain expressions used in astrological texts that are earlier than the 7th century B.C. it would appear, indeed, that the beginnings at least of the calculation of sun and moon eclipses belong to the earlier period, but here, too, the chief work accomplished was after 400 B.C., and the defectiveness of early Babylonian astronomy may be gathered from the fact that as late as the 6th century B.C. an error of almost an entire month was made by the Babylonian astronomers in the attempt to determine through calculation the beginning of a certain year.
In a general way, the reign of law and order in the movements of the heavenly bodies was recognized, and indeed must have exercised an influence at an early period in leading to the rise of a methodical divination that was certainly of a much higher order than the examination of an animal's liver.
However, the importance that was laid upon the endless variations in the form of the phenomena and the equally numerous apparent deviations from what were regarded as normal conditions, prevented for a long time the rise of any serious study of astronomy beyond what was needed for the purely practical purposes that the priests as "inspectors" of the heavens (as they were also the "inspectors" of the sacrificial livers) had in mind.
Thirdly, we have, probably as early as the days of Khammurabi, i.e. c. 2000 B.C., the combinations of prominent groups of stars with outlines of pictures fantastically put together, but there is no evidence that prior to 700 B.C. more than a number of the constellations of our zodiac had become part of the current astronomy.
The spread of astrology from Babylonia
Bouché-Leclercq, Cumont and Boll hold that the middle of the 4th century B.C. is when Babylonian astrology began to firmly enter western culture. At this point, it entered Greek and Roman culture, from whence it would exercise a strong hold on all nations and groups - particularly in Egypt - that came within the sphere of Greek and Roman influence.
"Chaldaean wisdom" became among Greeks and Romans the synonym of divination through the planets and stars, and it is perhaps not surprising that in the course of time to be known as a "Chaldaean" carried with it frequently the suspicion of charlatanry and of more or less willful deception.
The spread of astrology beyond Babylonia is thus concomitant with the rise of a truly scientific astronomy in Babylonia itself, which in turn is due to the intellectual impulse afforded by the contact with new forms of culture from both the East and the West.
