About the QHDC
The QHDC is a two year correspondence course leading to a thorough understanding of horary astrology. Central to the course is the study of William Lilly's "Christian Astrology"(1647) which is the definitive work on the subject and perhaps the most remarkable book ever written on astrology.
This is an advanced and rewarding course demanding effort and concentration. The course was started by Olivia Barclay in 1984 and has students worldwide.
