The Thoth Tarot is a deck of tarot cards created by occultist Aleister Crowley and artist Lady Frieda Harris in the 1940s. The deck is based on the principles of Hermeticism, Qabalah, and Thelema, which are all esoteric systems of thought developed by Crowley. The artwork on the cards is heavily influenced by Egyptian mythology, as well as Crowley's own personal vision and understanding of the tarot. The deck was first published in 1969, after both Crowley and Harris had passed away.
