He claimed to be a spirit medium and a possessor of a secret technique of turning different metals in gold. Aftir his death, Kelly’s name was surrounded by numerous myth and legends involving the high and mighties of his time and he became a prototype for various folklore characters belonging to the alchemist-medium-charlatan type."The Stone of the Philosophers" is an essay by Edward Kelly. It tells of some significant, yet, perhaps, fictional episodes of Kelly biography, like his imprisonment in Bohemia and. But its main object is the manual of making the philosophers stone – the holy grail of alchemy, a mysterious substance capable of turning lead to gold and granting immortality. This tract contains quotations of other scientists and alchemists, as well as Kelly’s own thought on the subject.
