Crowley's Thoth Tarot represented the culmination of a lifetime of occult study and practice. With artist Lady Freida Harris, he condensed the core of his teaching into 78 cards of the tarot. DuQuette starts with the basic historical perspective of the deck, then delves into descriptions of each card in depth, from both a purely tarot perspective and from an expanded magickal point of view. These insights will be of interest to anyone who uses the Crowley deck, and will be treasures by students of Crowley's work.
