This exquisite hardcover edition reprints the 1928 perennial bestseller of the remarkable resource compiled by the founder of the Philosophical Research Society, Manly P. Hall. Acclaimed by Publishers Weekly as "a classic reference, dizzying in its breadth," this comprehensive, well-researched encyclopedia of the occult distills ancient and modern teachings of nearly 600 experts, examining the secrets of Isis along with arcane aspects of mystic Christianity and other religions--in addition to covering topics as diverse as Kabbalah, alchemy, cryptology, and tarot, along with Masonry, gemology, and the identity of William Shakespeare. Sixteen pages of color plates and over 100 black-and-white images by the celebrated illustrator J. Augustus Knapp illuminate this keepsake, making it the perfect gift for the seeker of hidden knowledge.
