Ltd. ed. 73/650. Clavis Arcana Magica is an unusual text for Hockley in that it is largely concerned with what might be considered "black magic." As Alan Thorogood describes in his Introduction, it gives instruction for the performance of a number of magical workings, the details of which were said to have been obtained for Hockley via his seer Emma, during a series of scrying operations undertaken between 1853 and 1856. The workings are preceded by instructions including the form of the "call to the crystal," the exorcism and the discharge. The first working outlines a method to call the spirits of five material substances or organisms for the purpose of receiving cognate visions, the second is a variety of praestigia for the revivification of animal as well as plant species, the third outlines the construction of a talisman which permits the operator to enter the “spirit state” while asleep, and the fourth is necromantic ritual said to be "of marvellous power and force." This first publication of the text comprises an Introduction by Alan Thorogood, followed by a typeset transcription of the text of the manuscript, with explanatory footnotes, etc., and a facsimile of the original Hockley manuscript.
