Good afternoon,

Robert Zoller, one of the outstanding Mediaeval astrologers alive and author of excellent courses on it found here:

http://www.new-library.com/info/courses+74.html

published an entire book on the lots in 1989:

The Arabic Parts in Astrology: A Lost Key to Prediction

The first chapter alone, in which the author derives the planetary qualities from the monad, is in my humble opinion already worth the entire book. Mr Zoller did not attribute 'heat' to Zeus. We might recall that the Dorothean triplicity rulerships are based on earlier Stoic philosophy of elements (Fire-hot, Air-cold, Water-wet, Earth-dry), not on Aristotelian ones of the later Mediaeval tradition that qualifies e. g. Air as warm and moist. The first review at Amazon by Mr Kristopher Streeter is insightful. Were Mr Zoller to publish a second, revised edition, he would probably apply several of Mr Streeter's suggestions.

In his book and in his "Foundation Course" Mr Zoller emphasises that lots are NOT meant to be used stand-alone, but only as a last step in methodical house delineation.

Concerning lots' possible combustion and under Helios' beams, 'One Mediaeval author does not consensus make.' Who has tested this in many charts and can report on findings?

Best regards,
