The Magus, Celestial Intelligencer: A Complete System of Occult Philosophy (Forgotten Books)
About the Author:"Francis Barrett (born probably in London around 1770-1780) was an English occultist.Barrett, an Englishman, claimed himself to be a student of chemistry, metaphysics, and natural occult philosophy. He was known to be an extreme eccentric who gave lessons in the magical arts in his apartment and fastidiously translated Kabbalistic and other ancient texts into English.He was very enthusiastic about reviving interest in the occult arts, and published a magical textbook called The Magus. Apart from possibly influencing the English occult novelist Bulwer-Lytton, the book gained little notice until it influenced Eliphas Levi.The Magus dealt with the natural magic of herbs and stones, magnetism, talismanic magic, alchemy, numerology, the elements, and biographies of famous adepts from history.The Magus also served as an advertising tool. In it Barrett sought interested people wanting to help form his magic circle. An advertisement in The Magus (Vol. 2, p. 140) refers to an otherwise unknown school founded by Barrett."(Quote from wikipedia.org)
