The first authentic record on this subject (alchemy) is an edict of Diocletian, about 300 years after Christ, ordering a diligent search to be made in Egypt for all the ancient books which treated of the art of making gold and silver, that they might be consigned to the flames. This edict necessarily presumes a certain antiquity to the pursuit; and fabulous history has recorded Solomon, Pythagoras, and Hermes among its distinguished votaries.
