Arthur Edward Waite - the Pictorial Key to the Tarot

The Pictorial Key to the Tarot is A. E. Waite's influential guide to divinatory tarot, published in England in 1910 in conjunction with the Rider-Waite-Smith deck. While Waite was an occultist, he was very concerned with the accuracy of the symbols he used for his deck, and he did much research into the traditions, interpretations, and history behind the cards.
