Sect in Astrology: Day vs. Night Birth Charts

In episode 274 of the podcast Chris Brennan gives a detailed overview of the concept of sect in astrology, which is the difference between day and night birth charts. Sect is a fundamental concept that was used in Hellenistic astrology, but it has only been recovered by contemporary astrologers over the past 30 years through translations of ancient texts. The purpose of this talk is to give a broad introduction to sect, first by establishing how pervasive the concept is in ancient astrology, and then to demonstrate how it works in practice through chart examples.
