We’ll discuss what distinguishes one house system from another, promoting a better historic understanding of why they were invented and take a look at the features of each house system and compare them. This will allow the student to make informed choices on which ones they might want to use in their practice, and for what purpose.
In this course we will cover ecliptic-based (Whole Sign, Equal and Porphyry), space-based (Meridian, Regiomontanus, Campanus), and time-based houses (Alcabitius, Koch, Placidus, and Topocentric).
