Astrologer Rhys Redmond Chatham presents a talk in three videos on Astrological House Division. In this talk he shows how the various astrological house systems are calculated (no math is required!).
In the first video Rhys introduces himself and his background as an astrologer and gives a tour of the various great celestial circles used in house calculation.
In the second video, he goes into detail on how the houses are calculated, starting with the first two categories of house division:
(1) The ecliptic-based houses – whole sign houses, equal house system and Porphyry Houses – and then,
(2) The space-based houses – the Meridian House System, Morinus, Regiomontanus and Campanus Houses.
In the third video, Rhys covers the time-based houses: Alcabitius, Kohn, and Placidus Houses, and then wraps up the talk with conclusions and possible next steps.
