About Edward Kelley, Knight
Sir Edward Kelley or Kelly, also known as Edward Talbot (August 11, 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. (More at Wikipedia)
