I’m in the process of writing a book on traditional natal astrology, and I was fininshing up a chapter which was a lengthy analysis of a single natal chart, using an outline I drew up.
I use the Whole Sign house system, which is probably the oldest house system extant in the West, going back to the Hellenistic era.
It went well, and as I approached the end of the chapter I saw that the interpretation was accurate, powerful, specific, grounded, detailed – and incomplete.
