The Book of Thoth : A Short Essay on the Tarot of the Egyptians is the title of The Equinox, volume III, number 5, by English author and occultist Aleister Crowley. The book is recorded in the vernal equinox of 1944 (an Ixviii Sol in 0° 0' 0" Aries, March 21, 1944 e. v. 5:29 p.m.) and was originally published in an edition limited to 200 numbered and signed copies.
Aleister Crowley, the greatest Magus of the twentieth century, redefined the very basis of the Western Esoteric Tradition. His incalculably vast influence reaches through all modern occultism. Whether acknowledged or not, he is the father of the modern arts of ceremonial magick, western tantra, tarot and wicca. His devotees ascribe even greater significance to his life, regarding him as the Prophet of the Modern Age.
