McLean has transcribed the text of Harley 6482 (on Angel Magic) in its entirety, modernizing the spelling in places but remaining as loyal as possible to the style of Dr. Rudd. McLean believes this Treatise was written by Rudd for use by a group of practicing occultists centered around him.
A Treatise on Angel Magic includes detailed sections on the Schemhamphoras, the 72 Angels that bear the name of God/ the hierarchies of the fallen angels/ rapturous Images of the Mansions of the Moon/ evocation of the Natura Spirits/ and John Dee’s Enochian system of Angel conjuration. It concludes with Dr. Rudd’s Treatise on the Nine Hierarchies of Angels and their conjuration to visible appearance.
A Treatise on Angel Magic is an outstandingly complex source work on Angel Magic, and a resource that brings together several seminal texts not available anywhere else. Essential for scholars and students of the occult, the book offers not merely one viewpoint on western esoterica but instead encompasses all of the important thinking on these topics present in Medieval and Renaissance times.
