Western Astrology / Traditional Astrology
Clavis Astrologiae Elimata, or A Key to the Whole Art of Astrology (1676) is the enlarged second edition of Henry Coley's comprehensive astrological encyclopaedia, first published in 1669. Coley, who was the principal student and designated successor of William Lilly, covers all branches of the art in three parts: the principles of astrology including signs, planets, and aspects; horary and electional judgements; and natal astrology including directions and revolutions. The work includes the Rudolphine astronomical tables and was dedicated to Elias Ashmole, with an endorsing preface by William Lilly himself, making it the most authoritative continuation of the Lilly tradition.
