Sepharial, a 19th-century astrologer, went under the pseudonym "Sepharial" after an angel in the apocryphal Book of Enoch. Sepharial, a famous English Theosophist, was a well-known and recognized astrologer in the late nineteenth and early twentieth century, having written multiple works, some of which are still highly valued in some circles today. He was the editor of Old Moore's Almanac, which is still published in the twenty-first century. As a young man, Sepharial studied medicine before moving on to psychology, oriental languages, astrology, and numerology. In 1886, he began writing an astrology issue page in the Society Times, answering public concerns, and in 1887, he was inducted to the Theosophical Society's "inner sanctum". Sepharial was a prominent author in the disciplines of occultism, astrology, and numerology, and his writings had a significant impact on Alfred H. Barley and Alan Leo, whom he brought to Theosophy. He is credited as the first astrologer to incorporate Waltemath, Earth's hypothetical natural satellite, in his calculations. Lilith is referred to as the "dark moon" because he believes it is black enough to be unseen most of the time. Many of his novels and other works were put together in a haphazard manner, making his fame less durable than it could have been. Sepharial has founded several astrology periodicals, all of which failed to establish themselves.
