This book was first published in Paris in 1927, and an English edition did not appear until 1985. Wirth shows deep understanding of the tarot and various esoteric subjects to which it is linked. He starts by looking at tarot card patterns, the Kabbalistic tarot, the astronomical tarot, and notions of symbolism. The major arcana are then elucidated in terms of the initiatory journey. Wirth has a good grasp of the issues involved. A most helpful insight he makes is that the first eleven cards relate to the self mastery developed by the Magus. The last eleven cards relate to the Mystic's path of renunciation. This shows how the two paths are related, and need not be separate as is sometimes claimed. Wirth has a positive view of divination, seeing it as `the education of the imagination.' He gives informative instruction on divination. I do have a proviso about card six. Wirth calls it The Lover, showing a man deciding between two women, Virtue and Sensuality. Paul Foster Case considers the "two paths" interpretation erroneous. I find card six as depicted in the Case and Colman-Waite decks as The Lovers to be more helpful.The man represents the conscious mind and the woman the subconscious mind. It tells us that the way to higher consciousness, symbolized by Raphael, is through the subconscious mind.
