Peter Marshall set off on a quest to the places where astrology has been practiced for millennia—China, India, the Middle East, and Europe. Initially skeptical, Marshall was eventually persuaded by his research and travels that astrology not only contains the psychology of antiquity, but also offers profoundly modern insights into the workings of the mind. Astrology conveys important truths about the human character and the course of history, he argues, and can help us find our true place and purpose in the universe.
