Sir Edward Kelley or Kelly, also known as Edward Talbot (1 August 1555 – 25 November 1597), was an ambiguous figure in English  Renaissance occultism and self-declared spirit medium who worked with John Dee in his magical investigations. Besides the professed ability to summon spirits or angels in a "shew-stone" or mirror, which John Dee so valued, Kelley also claimed to possess the secret of transmuting base metals into gold, the goal of alchemy, as well as the supposed Philosopher's Stone itself.
