Sepharial, born Walter Gorn Old (1864-1929), was an influential English astrologer, numerologist, and author, whose esoteric interests extended into the realm of the occult and psychic phenomena. His nom de plume, 'Sepharial,' is an allusion to the spiritual and mystical elements that permeate his work. A contemporary of the famed mystic Madame Blavatsky, Sepharial became a prominent member of the Theosophical Society, which further honed his metaphysical worldview. He holds the distinction of being one of the first astrologers to bring this ancient practice to the English-speaking populace through prolific writings and public lectures. Sepharial's literary output was substantial, with 'How to Read the Crystal' being among his more notable works, providing detailed guidance on crystal gazing and clairvoyance. His literary style often incorporated a combination of scholarly exposition with practical instruction, aimed at enabling readers to explore the metaphysical realm themselves. Sepharial's influence on the New Age movement and modern astrological and occult practices remains notable, as his books continue to be referenced for their insight into the mystical arts.
