DEE, JOHN

born July 13, 1527, London, Eng. died December 1608, Mortlake, Surrey English alchemist, astrologer, and mathematician who contributed greatly to the revival of interest in mathematics in England. After lecturing and studying on the European continent between 1547 and 1550, Dee returned to England in 1551 and was granted a pension by the government. Dee became astrologer to the queen, Mary Tudor, and shortly thereafter was imprisoned for being a magician but was released in 1555. Besides practicing astrology and horoscopy in the court of Elizabeth I, whose favour he enjoyed, he also gave instruction and advice to pilots and navigators who were exploring the New World. He was asked to name a propitious day for Elizabeth's coronation, and he gave her lessons in the mystical interpretation of his writings. In 1570 the first English translation of Euclid's work appeared, and, although it is credited to Sir Henry Billingsley, who became sheriff and later lord mayor of London, Dee probably wrote part or all of it. In addition, he wrote the preface, which encouraged the growing interest in the mathematical arts. Dee later toured Poland and Bohemia (158389), giving exhibitions of magic at the courts of various princes. He became warden of Manchester College in 1595.
