Episode 42: Chris Brennan on Hellenistic Astrology

In this episode we discuss the nitty-gritty of Hellenistic astrology, trying to get at how it might have actually been practised in the Hellenistic and Roman periods. But it would be silly to interview an experienced astrologer like Chris Brennan without taking full advantage of his expertise, so a lot of material is covered which makes this episode an excellent introduction to technical astrological matters more generally. The conversation has four main sections:

  • We cover basic terminology – how do you tell your natal astrology from your inceptional astrology?
  • We look at the fourfold typology for Hellenistic astrology laid out in Chris’ book (see below), discussing the implications of each of the four components of the schema.
  • We take a look at the practicalities of ancient astrology. It’s the first century and I am visiting an astrologer with my newborn baby to get its chart read. What happens next? Astrology is unique among ancient occult sciences in that we have procedural texts (as well as some fascinating artefacts!) which give us a pretty solid glimpse into what must have gone on in an ancient astrological consultation.
  • I put my own proposed definition of astrology from Episode 41 to Chris, defining astrology as 1) the belief in astral causation and the resultant ideas about human action coupled with 2) Hellenistic cosmology, the zodiac, and 3) the horoscopic and/or electional modes of divination, and he takes me to school in a big way, resulting in an on-the-spot definitional refinement which will stand the podcast in good stead for many episodes to come.
