In 1904, Aleister Crowley commissioned, edited, and introduced an English translation of The Book of the Goetia of Solomon the King, the first of five magical texts known as the Lemegeton. Yet, few have actually worked the system, believing one must conform blindly to the archaic procedures and long-winded conjurations of the original text. But Crowley's attitude toward the Goetia appears to have been different. His masterful expansion and perfection of the "Preliminary Invocation of the Goetia" is a prime example. Now, Christopher Hyatt has joined with Lon Milo DuQuette and David P. Wilson to glean extraordinary magical and philosophical treasures from this most misunderstood subject.
