An Encyclopedic Outline of Masonic, Hermetic, Qabbalistic and Rosicrucian Symbolical Philosophy

Manly Palmer Hall was a Canadian-born author, lecturer, astrologer, and mystic. The Secret Teachings of All Ages is a comprehensive compendium of the ancient occult and esoteric traditions of the world. It looks at the schools of philosophy down the ages, in respect of their origins, notable characters, and influences on civilization. The vast scope of this classic work examines the ancient mythology, ritual, symbolism, arcane, and mystical teachings of, among others, the Druids, Mithraism, Christianity, Gnosticism, Platonism, Hermeticism, the Chaldeans, Paracelsus, Rosicrucianism, and other secret societies. The subjects covered include alchemy, cryptology, Kabbalah, and the Tarot. A valuable source for students of history, philosophy, or mythology.
