Discovered in a hidden compartment of an old chest long after his death, the secret writings of John Dee, one of the leading scientists and occultists of Elizabethan England, record in minute detail his research into the occult. Dee concealed his treatises on the nature of humankind's contact with angelic realms and languages throughout his life, and they were nearly lost forever. In his brief biography of John Dee, Joseph Peterson calls him a "true Renaissance man"? detailing his work in astronomy, mathematics, navigation, the arts, astrology, and the occult sciences. He was even thought to be the model for Shakespeare's Prospero.

All this was preparation for Dee's main achievement: five books, revealed and transcribed between March 1582 and May 1583, bringing to light mysteries and truths that scholars and adepts have been struggling to understand and use ever since. These books detail his system for communicating with the angels, and reveal that the angels were interested in and involved with the exploration and colonization of the New World, and in heralding in a new age or new world order. While Dee's influence was certainly felt in his lifetime, his popularity has grown tremendously since. His system was used and adapted by the Hermetic Order of the Golden Dawn, and subsequently by Aleister Crowley.

This new edition of John Dee's Five Books of Mystery is by far the most accessible and complete published to date. Peterson has translated Latin terms and added copious footnotes, putting the instructions and references into context for the modern reader.
