The Book of Rulerships: Keywords from Classical Astrology
I wrote this book because it's easy for people to casually decide upon an astrological rulership, but it's hard to know whether where that idea came from: what lineage, whether it was just an idea, or something that the astrologer in question actually worked with.This books lists rulerships by source, including Ptolemy, al-Biruni, Gadbury, Lilly, and others.
