Sir Edward Kelley or Kelly, also known as Edward Talbot (August 1, 1555 – November 1, 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 on a crystal ball, which John Dee so valued, Kelley also claimed to possess the secret of transmuting base metals into gold.
Legends began to surround Kelley shortly after his death. His flamboyant biography, and his relative notoriety among English-speaking historians (chiefly because of his association with Dee) may have made him the source for the folklorical image of the alchemist-charlatan.
Involved in the development of the Enochian language, and possibly linked to the selling of the Voynich Manuscript to Rudolf II. (The VM has been dated to over a century before the time of Kelly and Dee, so was not their creation.)
