Manual of Occultism

Sepharial's manual offers an introductory survey of occult theory and practice as understood in the late nineteenth and early twentieth centuries. It is historically notable as a compact guide to popular esoteric ideas of the period, and readers will find explanations of clairvoyance, psychic forces, astrology, ceremonial principles, and related occult doctrines.

Sepharial was the pen name of Walter Gorn Old (1864–1929), an English astrologer and occult author. He wrote extensively on astrology, esoteric symbolism, and related occult topics, and was one of the more prolific popularizers of astrological literature in the late nineteenth and early twentieth centuries.
