This work, revised and reissued after original publication some 20 years ago, takes a broad look at three aspects of Chinese astrology: its foundation in Chinese astronomical observation, its historical development, and the method of interpreting the portents. Included is some source material from early Zhou and Han texts that give a sense of what Chinese astrology was like before it was touched by Western concepts, providing the reader a fascinating insight into the Chinese mind. Chapters on pentology, the Chinese calendar, the 28 lunar mansions, early Chinese astronomical texts, the astrological treatise of Ssu ma Ch'ien (Si Ma Jian), divination plates and feng shui, and Chinese horoscopes make for a readable and interesting presentation.
