I would like to extend to all a belated welcome to this Hellenistic Astrology forum. Although I am sure that we will end up exploring in detail many technical issues and concepts on this forum, it is my hope that we do not ignore some of the broader implications and themes of Hellenistic Astrology. In that vein, let me start out by making a few comments by way of orienting you to some of the positions I have come to after translating and studying Hellenistic Astrology for the past 18 years.
First, Hellenistic Astrology is the foundation of all later Western Astrology. Although it certainly inherited some concepts from Babylonian and pre-Hellenistic Egyptian astrology, it made them its own in a characteristic manner, and introduced a vast number of other concepts and techniques for which there does not seem to be any historical precedent. Most of the concepts and many of the techniques of modern astrology can be traced back to Hellenistic astrology as their source, although 20th century astrology radically re-conceptualized them. However, only about half of the original technical apparatus of Hellenistic astrology survived transmission to modern times.
Secondly, according to the best documentary evidence, Hellenistic Astrology came on the scene very suddenly sometime in the second or first century B.C.E. and emerged complete in a very short period of time. This suggests that there was a single shaping intelligence behind its origin—that is was the result of one man or a small school of men working together. It could hardly have been the outcome of centuries of empirical study correlating celestial phenomena with human events. Not only that, but many of its concepts could not even in principle have been discovered empirically. (That is not to say that they could not be tested empirically.) Instead, I maintain that Hellenistic Astrology was an inspired rational construct, by which I do not mean that it was simply made up whole cloth.
Thirdly, the original astrology of the Hellenistic period was highly systematic—not so much in the manner of its exposition, but in the interrelationship of its first principles and the organization of its practical concepts and techniques. (It would be hard to account for its demonstrable systematic integrity if Hellenistic Astrology had been an eclectic synthesis of the work of numerous astrologers working independently.) In fact, I maintain that it was more systematic than any astrology before or since. I am not necessarily claiming systematic integrity as a virtue for astrology; I am simply stating the results of my investigations.
Fourthly, there are no surviving treatises addressed to the theoretical precepts that underlie the Hellenistic Astrology of the founding period, nor even any references to them. This leads me to believe that the original foundations must have been fully embedded in its practical system. We cannot presuppose, therefore, that Hellenistic Astrology was based on the teachings of the Stoics, the Middle-Platonists, the Neo-Pythagoreans, or any one of the other Greek schools. The theoretical precepts that guided the founders must be teased out of the practical system itself.
Fifthly, I do not think that Hellenistic Astrology was intended to be a divinatory art by its founders, if by divination we mean a way of understanding the will of the gods (as the Babylonians evidently understood their astrology). One of the reasons I hold this opinion is the lack of anything like horary astrology in our surviving sources, horary being arguably a divinatory application of astrology. I maintain instead that it was developed as a discipline for rendering human life intelligible (and meaningful) in the manner of a Classical Greek epistēmē—that is, a way of coming to knowledge about a given human life as a whole.
I am aware that all of the above contentions have been challenged by one or more students of traditional astrology. Comments, anyone?
