multipliers might possibly affect the value of the king's coin. Henry VI., a very pious, yet very weak and credulous prince, was as great a patron of the alchemists as Edward III. had been before him. These impostors practised with admirable success upon his weakness and credulity, repeatedly inducing him to advance them money wherewith to prosecute the operations, as well as procuring from him protections (which he sometimes prevailed upon the Parliament to confirm) from the penalties of the statute just mentioned.[17] In 1438, the king commissioned three philosophers to make the precious metals; but, as might be expected, he received no returns from them in gold or silver.[18] His credulity, however, seems to have been unshaken by disappointment, and we next find him issuing one of these protections, which is too long to print entire, granted to the "three famous men," John Fauceby, John Kirkeby, and John Ragny, which was confirmed by Parliament May 31, 1456. In this document the object of the researches of these "philosophers" is described to be "a certain most precious medicine, called by some philosophers 'the mother and empress of medicines;' by some, 'the inestimable glory;' by others, 'the quintessence;' by others, 'the philosopher's stone;' by others, 'the elixir of life;' which cures all curable diseases with ease; prolongs human life in perfect vigour of faculty to its utmost natural term; heals all healable wounds; is a most sovereign antidote against all poisons; and is capable of preserving to us and our kingdom other great advantages, such as the transmutation of other metals into the most real and finest gold and silver."[19] Fauceby, here mentioned, is elsewhere designated the king's physician.[20] We have not traced the position of the other two adepts named. Fauceby, however, notwithstanding his power of gold-making, did not refuse to accept a grant from the king, in 1456, of a pension of 100_l._ a year for life.[21]
