Due to the significant progress of Astronomy, Statistics and of calculation techniques, the discipline of Astrology is constantly evolving. In this work Ciro Discepolo aims at recapitulating and systematizing contemporary astrological knowledge. The present volume follows the famous attempt of Henri-J. Gouchon (Dictionnaire astrologique, Dervy-Livres, 1975), of which Discepolo's work is an update. In his "summa astrologica," Discepolo: - informs his readers about the news in the field of Astrology, of which he is a leading figure in Italy today; - complements Gouchon's work with a number of new entries or updates (such as Aids, Astrocartography, Courage, Drowning, Libido, Suicide, Synchronicity); - offers a generous contribution of original and first-hand interpretations; - provides hundreds of Natal Charts illustrating a high number of entries with a specific didactic purpose. This volume is intended for consultation; it is exhaustive and concise at the same time, and its reading from A to Z will prove extremely pleasant for its fresh and lively style.
