Course Description

The Ancient Aspect Doctrine Class contains two detailed lectures on reconstructing and applying the original aspect doctrine used in Hellenistic astrology.

One of the lectures offers a new reconstruction of a highly complex aspect doctrine that existed in the early astrological tradition, and provides insight into how those techniques can be used in order to improve chart delineations today.

The material contained in this module has been extracted from part 5 of the Hellenistic Astrology Course, and is also available as part of the complete course. This class is for those who only want to study the Hellenistic approach to the aspect doctrine on its own.

Description of the Class

The primary focus of the module is a seven and a half hour lecture presented by Chris Brennan titled The Doctrine of Configurations in Hellenistic Astrology.

The purpose of this lecture is to present a new reconstruction of the original aspect doctrine in Hellenistic astrology. This is accomplished through the analysis and comparison of several ancient astrological texts which preserve a lost set of definitions by the first century astrologer Antiochus of Athens.

The reconstruction of these definitions not only provides insight into the highly complex aspect doctrine of the early western astrological tradition, but it also provides contemporary astrologers with a powerful new set of tools for the analysis of planetary condition.

The lecture covers definitions such as: witnessing, right and left, overcoming, hurling rays, enclosure, intervention, guardianship, counteraction, domination, bonification, maltreatment, and more.

The reconstruction presented in the lecture is partially based on a collaboration between Demetra George, Benjamin Dykes and Chris Brennan. It is presented here for the first time in its entirety.
