This is the first in a trio of books that together form The Complete Enochian Chess. Enochian Chess in part comes from the Elizabethan system of Enochian Magic originated by the Court Astrologer, Dr John Dee. It was developed into its current form in Victorian times by SL MacGregor Mathers and William Wynn Westcott. This book includes a complete facsimile and commentary of Moina Mathers's Alpha et Omega Enochian Chess papers together with a brief history of the game, notes on play and strategy, and instructions for Active divinatory methods utilised by this system. Notes and illustrations by Ithell Colquhoun (some previously unpublished) help explain this advanced system of magick in its own right. Originally it was only taught to Golden Dawn initiates who had risen to the rank of Zelator Adeptus Minor, and required a comprehensive knowledge of Tarot, Geomancy, Kabbalah, various magical formulae, the symbolism of the Candidate, the Ceremony of the Neophyte Grade, the art of Invocation and Banishing, Pentagram and Hexagram rituals, formation of Telesmatic Images, Sigils, and the Enochian Tablets. Enochian Chess subsumes other Passive systems of divination such as Tarot and astrology, and has powerful prophetic properties.
