The Hellenistic Doctrine of the Topical Places (a.k.a. "houses")
The significations of the houses in Hellenistic astrology resulted from a fusion of two different systems: an eight-topic system that is largely devoted to the native's family members, and a twelve-topic system that concerns events in the native's life. The rationale behind each of these two systems will be explained. From this the basic meanings of the houses can be readily derived, as well as the principles underlying the delineation of planets in houses and the rulers of these houses.
