John Dee (1527-1608), English mathematician, astronomer, navigation expert, the author of Mathematical Preface to Euclid's Elements, was also interested in alchemy and hermetic philosophy. Dee served as a consultant to Queen Elizabeth I and from 1586 to 1589 he worked at the court of the Rosenbergs in South Bohemia.
