Originally published in 1985, this Dictionary remains a reliable and comprehensive guide to astrological terminology. It forms a reference and sourcebook for general astrological studies and includes terms derived from the major post-medieval sources of astrology, up to and including modern forms of astrology practised up to the late 20th century. Under more than 3000 headings the Dictionary gives definitions which will be clear to the non-specialist investigator but still detailed enough for the requirements of the practical astrologer. It re-examines ancient terminologies to clear up some general misconceptions and gives firm definitions to many ancient and modern terms. Twentieth century developments in the study of literature and history emphasized the importance of astrology to such authors as Dante, Chaucer and Shakespeare. The Dictionary of Astrology gives a working knowledge of an important tradition which was once the backbone of philosophy and art.
