John Dee: scientist, or sorceror? Much evidence suggests he inspired Marlowe’s Faustus, Shakespeare’s Prospero, and Ben Johnson’s The Alchemist. He spent much of his life studying alchemy, divination, mathematics, and Hermetic philosophy -- and his library, it's said, housed an amazing 4,000 works. He was accused of using mathematics, of being a conjurer, and of spying for the English crown - which makes sense, because it's rumored John influenced the character of James Bond.
