Book excerpt: Karl Kerényi presents here a beautiful, authoritative study of the great god Hermes whom the Greeks revered as Guides of Souls. Chapters on Hermes and Night, Hermes and Eros, and Hermes and the goddesses illuminate the complex role of Hermes in classical mythology, while also providing an archetypal background for the guiding of souls in psychotherapy. A vital contribution both to the study of the classics and the therapy of the soul.
