Ancient Whispers From Chaldea: Making Babylonian Astrology Work for You, by Arthyr W. Chadbourne. The ancient Chaldeans devised one of the most unique astrological systems ever, now available to the modern astrologer. They discovered that a lifetime is actually encapsulated within the 24-hour period of the day of birth. Their unique use of the "lunar mansion" was more revealing than today's sun sign system. And their method of "aging" charts to predict the timing of trends and circumstances offers a quick and simple method of prediction. The most innovative book on astrology in 1,700 years!
