Henry Coley’s main astrological texbook Clavis Astrologiae Elimata or a Key to the Whole Art of Astrology (1676) was a major expansion of his earlier and less common Clavis Astrologiae. It is considered one of the most important 17th century astrological textbooks for the study of horary astrology after that of William Lilly, and also includes a substantial section on nativities. Originals are rarely found to be complete, but this one was.
