Phoebe Wyss, an experienced astrologer, here examines all aspects of astrology in the light of the emerging worldview known as archetypal cosmology. She sets out by exploring the classical roots of astrology in sources of wisdom found in the ancient Egyptian mysteries. She then follows the tradition to modern times through C.G. Jung's ideas on the nature of the psyche. She also discovers that the claims of astrology are entirely compatible with new cosmological thinking as envisioned by post-modern physics and chaos theory. In the second part of the book, she proposes that the mathematical basis of astrology and the components of astrological charts are both archetypal and cosmic in scope. She argues that the twelve astrological archetypes make up a single 'cosmic mind', whose patterns are imprinted on all our individual minds. Finally, she exemplifies this radical approach to astrology through an interpretation of the chart of William Blake.
