This book is a transcript of the first term of an introductory course in astrology given for the Centre for Psychological Astrology. In this first of three volumes, the basic building blocks of astrological language are presented. The reader is taken on a fascinating journey through the solar system, the ancient planetary gods, and the energies and motivations symbolised by their astrological equivalents; and then through the signs of the zodiac, their elements and qualities, and the ways in which different planets express through them. Alchemical symbolism is included as a parallel map of the individual journey. The book is well-illustrated, and is worthwhile reading for both the beginner as well as the more advanced astrological student.
