The first facsimile edition of this masterwork of Hermeticism and Magick, described by its author as "the most remarkable book on the Mystic Path ever written." It has long been treasured by students and collectors in its first edition of 1907. Crowley poured his occult knowledge, particularly that which he learned in the Hermetic Order of the Golden Dawn, into the four essays contained therein. It is an essential work for all students of the Golden Dawn and Magick.
