I WANT to thank the editor, Deborah Wesley, warmly for her successful efforts to transform rough and scattered material into a relatively smooth and unified whole. Jung said that “any renewal not deeply rooted in the best spiritual tradition is ephemeral.” Greek mythology is the foundation of one part of our “best spiritual tradition,” and Jung has given us the means to assimilate this rich storehouse of archetypal imagery to the modern mind. May this book contribute to that goal.
