The names of the Enochian angels are drawn from a number of enciphered tables, received through the "spirit actions" of John Dee, Edward Kelly (and occasionally another scryer). The Watchtower set of angels is one of the larger and better developed sets. A Problem arises in that there are several variations on the Watchtowers themselves and several ways of drawing the names therefrom. The four Watchtowers were first received on 25 June 1584. This arrangement and order is reflected in Dee's prayer - The Fundamental Obeisance. They were then rearranged slightly and corrected in the days following: 26 June through 2 July 1584; this arrangement corresponds to the majority of prayers in Sloane MS. 3191 (The Book of Earthly Victory and Science) and is what is given in the published versions of that text, notably Geoffrey James' Enochian Evocation / Magick and Robert Turner's Elizabethan Magic. Late in the course of Dee and Kelly's work together, on 18 April 1587, the Archangel Raphael, was said to have appeared, and reformed the Watchtowers, rearranging their order and directions and making some minor corrections. It is this arrangement that is used in the Golden Dawn and subsequent derivatives such as Thelema, Wicca and the Church of Satan. The Golden Dawn also follows a slightly different method of drawing forth some of the names from the Tables. The Golden Dawn method of extracting the names, is heavily influenced by the post Dee text contained in Sloane MS. 307 and published by Stephen Skinner and David Rankine as Practical Angel Magic of Dr John Dee's Enochian Tables. For convenience sake, in identifying these variations when they differ, the received set is labelled Received, the set reflected in Sloane MS. 3191 is labelled Orthodox, the set reformed by Raphael as Reformed and the variations used by the Golden Dawn as GD. The Angelic Hierarchies of the Watchtowers are also set out in several visions of Edward Kelly's and enshrined in a Talisman constructed by John Dee, published in A True & Faithful Relation and on display in the British Museum collection.
