The Goetia (Lemegeton) is perhaps the most famous grimoire after the Key of Solomon. This volume contains a transcription of a hitherto unpublished manuscript of the Lemegeton includes four whole grimoires: Liber Malorum Spituum seu Goetia Theurgia-Goetia Ars Paulina (Books 1 & 2) Ars Almadel This manuscript was owned by Dr. Thomas Rudd, a practicing scholar-magician of the early seventeenth century who knew Dr. John Dee. There are many editions of the Goetia, of which the most definitive is that of Joseph Peterson, but this volume shows how the Goetia was actually used by practicing magicians in the sixteenth and seventeenth centuries, before the knowledge of practical magic faded into obscurity. For example, to evoke the seventy-two demons of the Geotia, or the many other spirits listed here, requires more knowledge than is included in the grimoires themselves. It was well-known in times past that invocatio and ligatio, or binding, was a key part of evocation, but in the modern editions of the Goetia this key technique is expressed in just one word "Shemhamphorash," and its use is not explained. This volume explains how the 72 angels of the Shemhamphorash are used to bind the spirits, and the correct procedure for safely invoking them using dual seals with the necessary angel seal and Psalm. Also, for the first time, the exact form and use of the breastplate and Brass Vessel is explained.
