Dr. John Dee's system of angelic communication was the result of the a dramatic magical operation. It has survived to become the cornerstone of the modern ceremonial magician's practice. In 1582 Dee and his clairvoyant partner Edward Kelley made magical contact with a number of spiritual entities who identified themselves as angels - the same that communicated with Adam, Enoch, and the patriarchs of the Old Testament. Over the next three years they revealed to Dee and Kelley three distinct magical systems of vision magick. The third and last of these incorporated a series of 'calls' to be recited in an angelic language in order to raise the consciousness of the magician to a level where angelic contact is possible. Lon Milo DuQuette, who has practiced Dee's system for over twenty-five years, has seized upon elements of the original Dee material overlooked by adepts of the Golden Dawn, Aleister Crowley, and other modern magicians, and brought them to light in 'Enochian Vision Magick'. DuQuette offers the expert and novice alike the practical means by which they can become attuned in the same simple step-by-step manner that first prepared Dee and Kelley.
