The Black Arts is a fascinating and wonderfully readable exploration of the practice, theory, and underlying rationale of magick and occultism in all its branches, including witchcraft, spells, numerology, astrology, alchemy, kabbalah, tarot, charms, and summoning and control of spirits. This edition features a 50th anniversary introduction by historian of alternative spirituality Mitch Horowitz, who frames the book for a new generation of readers.
