This is a reproduction of a talisman design found in the "Key of Solomon", a grimoire of ceremonial magic attributed to King Solomon. Containing influences of Hermetic alchemy, Roman Astrology and Kabbalah, Solomon's magic is a cornerstone of the Western Esoteric occult tradition. The grimoire explains: "The Spirits herein written serve to bring to effect and to grant things which are contrary unto the order of Nature; and which are not contained under any other head. They easily give answer, but they can with difficulty be seen." Samuel Liddell MacGregor Mathers, a ceremonial magician and editor of the most common edition of the book, further describes: "The Letters form the Names of Böel and other Spirits."
