Revered in his time as the most learned man in all Europe, Dr. John Dee (1527-1608) was the leading British representative of sixteenth-century Hermeticism. He was Queen Elizabeth's personal astrologer and an honored advisor to many noble English families and European royalty. Besides his wide-ranging studies of the contemporary sciences, John Dee was famous, together with Edward Kelley, for his communication with angelic and spiritual beings by means of his crystal and the unique Enochian language.<BR>This anthology provides the general reader with a selection of Dee's writings illustrating his multifarious interests - from Hermetic and Cabalistic philosophy to mathematics, astronomy, astrology, and navigation. Drawing on such works as the Monas Hieroglyphica and the celebrated Preface to Euclid, as well as on the "Spiritual Diaries," Gerald Suster's selection reaffirms Dee's central position in the history of Renaissance esotericism and the development of Western Magic.
