Overview
This book describes the philosophy and the use of Aleister Crowley's Thoth Tarot, a deck of Tarot cards designed by Crowley himself and co-designed and painted by Lady Frieda Harris. The Thoth Tarot has become one of the best-selling and most popular Tarot Decks in the world.

The original signed limited edition was bound in Moroccan leather and printed on pre-wartime paper. Crowley sold £1,500 worth of the edition (equal to £57,540 in 2013) in less than three months.

Content
The book is divided into four major parts:


 * Part One: The Theory of the Tarot.
 * Part Two: The Atu (Keys or Trumps).
 * Part Three: The Court Cards.
 * Part Four: The Small Cards.

Part One is further divided into three chapters; Part Two into two chapters and an appendix; Part Three into one chapter; and Part Four into one chapter. The book includes a list of plates depicting the Tarot cards as seen by Crowley and Harris.

There is an Appendix A: the use of the Tarot in the Art of Divination; and an Appendix B which includes the obiter dictum: "the 'correspondences' are not arbitrary". Appendix B also includes the Key Scale of the Tree of Life with the conic sections of mathematics and a diagram attributing the trigrams of the I Ching to the ten Sephirot.
