Historical Astrology

The Assyrians placed as much or even more importance on the five planets they had identified and their movements into these constellations. The reason for this is that they believed the planets were gods or at least the home of gods. The names given to these planets as well as the sun and moon were eventually replaced by the Greek names, then the Roman names, and eventually the English names. In Assyrian times the names were as follows: Sun=Shamash, Moon=Sin, Venus=Ishtar, Mercury=Nebo or Nabu, Mars=Nergal, Saturn=Ninurta, and Jupiter=Marduk. The various personalities and domains of these gods changed with time and change of rulership.

The next phase in the history of astrology is the New Babylonian period (600-300 BC). Some of the prominent astrologers of this period were Kiddinu, Berossus, Antipatrus, Achinopoulus, and Sudines. Up to this point, really the only kind of astrology being practiced was omen astrology, or the foretelling of major events. It was during the New Babylonian period that the signs of the zodiac were invented and horoscope, or birth, astrology had its beginnings. As of 1996, sixteen Babylonian horoscopes have been found and it was not uncommon for these horoscopes to contain little or no prediction. They mostly consist of the position of the skies at the time of conception or birth of the individual.
The Greeks began their immense influence on astrology during the fifth and fourth centuries BC. Alexander the Great managed to spread the Greek way of life, also known as Hellenism, to places such as Alexandria and Antioch. The Hellenistic period spanned from the time of his death in 323 BC to the middle of the second century BC, when the Romans took the eastern Mediterranean. The Greeks were responsible for incorporating mythology into astrology. The names we are familiar with today when we think of mythology came into existence. Up to this point, the same gods existed, just under different names and personalities.
This was the age of such famous forerunners of modern science as Plato, Pythagoras, who asserted that the earth was round and traveled around the sun; Leucippus, whose theory would later be the beginnings of atomic science; and Aristotle. Other scientists involved with the study of astronomy, such as Eudoxus, held the opinion that astrology was ridiculous and no one should believe prediction about his life based on which day he was born. Nevertheless, astrologers such as Critodemus, Apollonius of Myndus, and Epigenes of Byzantium continued to refine horoscopic astrology.
The Romans were not as accepting of astrology. About 250 BC, a large number of the common citizenry became interested in astrology, but the conservatives fought against most any outside religion, including Christianity. They presented quite logical arguments against the use of astrology and horoscopes, saying that people born on the same day at the same time had very different destinies, and that people born on different days at different times sometimes died at the same times. Nevertheless, astrology spread into Rome, despite several attempts to expel all astrologers from the empire. Eventually, astrology gained acceptance, mostly because the Romans had a certain respect for the Greeks’ education. If the Romans had not finally allowed astrology into their culture, things might have been very different as far as the Egyptians’ contributions to the art.
