This is a quality, clothbound edition of magical texts graced with the scholarly commentary and textual analysis of Mr. Peterson. Seven exemplars (extant copies) of Ebenezer Sibley's Clavis were used for comparisons, the one owned by antiquarian/publisher Donald Weiser considered to be the most accurate and complete. It is this edition that is reproduced by facsimile here, inclusive of seven other independent texts as follows: The Mysterious Ring, which provides instructions for preparing magic rings; the Experiments of the Spirits Birto, Vassago, Agares, and Bealpharos, which instruct one how to call upon angels and spirits (Vassago and Agares are listed as goetic spirits in The Lesser Key of Solomon); The Wheel of Wisdom, which provides instruction for using celestial harmonies (and is supplemented with a color fold-out of the wheel with another version from manuscript Sloane 1307 provided in Appendix 2); and the Complete Book of Magic Science, which draws on a variety of sources and is more complete than the related text of The Secret Grimoire of Turiel and more accurate than the Teitan Press edition.
Peterson's knowledge of the grimoire tradition is evidenced by his informative introduction, detailed textual notes, and production of a Critically-Established Text which predominantly follows the Weiser manuscript, "except for substantive deviations that can be critically established from the limited number of available witnesses" (page xxi). The textual analysis includes reference to notable works such as Abano's Heptameron, Agrippa's Three Books of Occult Philosophy, Reginald Scot's expanded 1665 edition of his Discoverie of Witchcraft, the Arbatel, and The Magical Calendar, among others. Five related texts to Sibley's Clavis were also used for analysis, including manuscript Wellcome 4670 which was published along with Wellcome 4669 in an English translation through Skinner and Rankine's The Veritable Key of Solomon. In the Acknowledgments section, one also finds credit going to Peterson's daughters Sarah and Lisa who assisted with the artwork in Appendix 2, and his son Karl for providing a wonderful drawing of the wyvern which was missing from the manuscript. What awesome family support! This collectible edition of magical texts is a pleasure to own and reference.
