The Greater Key of Solomon
1914. Including a Clear and Precise Exposition of King Solomon's Secret Procedure, Its Mysteries and Magic Rites, Original Plates, Seals, Charms and Talismans. Translated from Ancient Manuscripts in the British Museum. The Key of Solomon, save for a cultailed and incomplete copy published in France in the seventeeth century, has never yet been printed, but has for centuries remained in Manuscript form inaccessible to all but the few fortunate scholars to whom the innermost recesses of the great libraries were open. The fountain-head and storehouse of Qabalistic Magic, and the origin of much of the ceremonial magic of Mideval times, the "Key" has been valued by Occult writers as a work of the highest authority. I see no reason to doubt the tradition which assigns the authorship of the "Key" to King Solomon, for among others Josephus, the Jewish historian, especially mentions the magical works attributed to that monarch; this is confirmed by many Eastern traditions, and his magical skill is frequently mentioned by the Old Adepts.
