This book situates Tarot in its ancient roots, with particular emphasis on the tradition of the Mystery Schools. The suites are designated as "Earth, Water, Air and Fire" rather than the conventional Pentacles, Cups, Swords and Wands. The first part of the book is a review of the ancient sources of Tarot and the dynamics of the archetypes, with interesting sidelights on the author's personal experiences in this realm. In chapters such as The Grammar of the Goddess, The Path of Serapis and An Ancient Temple Calverley uncovers evidence for the grounding of Tarot's internal structure in the esoteric wisdom of the ancient Mystery Schools. In the second part of the book, the writer follows The Fool on an adventure in which he experiences each of the figures of the Major Arcanum and arrives at the deeper wisdom which Tarot has to teach. He is instructed by The Magician, The Priestess and The Hermit about the meanings and wisdom of Tarot, which he discovers to be a "Book of Truth."
