This book is about the evocation of spirits and the cryptography associated with them. To date only Books I & III have been published in English but without the essential detailed Spirit Registers covering 32 spirits. This edition has rectified that deficiency, and has added a translation of Book II (containing a further 25 spirits) and Book IV which related the Steganographia to Paracelsus, the Almadel and the Shemhammaphorash of Solomon, Adam and Moses. So at last the whole Steganographia is available in English with full explanations by Stephen Skinner.
