Occultists - John Dee - Portrait of Dr. John Dee (1527-1608) the Elizabethan astrologer and magus, adviser to the Queen, and author of several occult books. From the 1790 engraving in Sibly's Illustration of the Occult Arts. - John Dee was a noted British mathematician, astronomer, astrologer, geographer, and consultant to Queen Elizabeth I. He also devoted much of his life to alchemy, divination, and Hermetic philosophy. Dee straddled the worlds of science and magic. One of the most learned men of his time, he had lectured to crowded halls at the University of Paris when still in his early twenties. He was an ardent promoter of mathematics, a respected astronomer and a leading expert in navigation, having trained many of those who would conduct England's voyages of discovery. At the same time, he immersed himself deeply in Christian angel-magic and Hermetic philosophy, devoting the last third of his life almost exclusively to these pursuits. - 固opFoto / CW
