Ars Theurgia

First numbered edition, limited to 333 copies
Translated, edited, and introduced by Paul Summers Young
 
The second book in our Lesser Key series is about how enthusiasts in the seventeenth century took Trithemius and his enigmatic Steganographia and drew out a method of spirit communication and experimentation that appears to possess a reach today far wider than the more famous Ars Goetia.
 
This volume includes a complete translation of the first book of the Steganographia, with the Ars Theurgia of Peter Smart/Dr. Rudd, John Harries' wonderfully chaotic hedgewizard version, and extracts illustrating the method of conjuration into a crystal taken from Reginald Scot, Meric Casaubon, Joseph Glanvill, and Francis Barrett, with a translation from Isidore of Seville on the compass points and climes.
