My companion looked ill at ease, as one who feels that he has been taken off his ground. ‘There was indeed one such at Nurnberg,’ he answered, ‘one Gervinus or Gervanus, who, the folk said, could turn an ingot of iron into an ingot of gold as easily as I turn this tobacco into ashes. Old Pappenheimer shut him up with a ton of metal, and threatened to put the thumbikins upon him unless he changed it into gold pieces. I can vouch for it that there was not a yellow boy there, for I was captain of the guard and searched the whole dungeon through. To my sorrow I say it, for I had myself added a small iron brazier to the heap, thinking that if there should be any such change it would be as well that I should have some small share in the experiment.’ ‘Alchemy, transmutation of metals, and the like have been set aside by true science,’ remarked the taller officer. ‘Even old Sir Thomas Browne of Norwich, who is ever ready to plead the cause of the ancients, can find nothing to say in favour of it. From Trismegistus downwards through Albertus Magnus, Aquinas, Raymond Lullius, Basil Valentine, Paracelsus, and the rest, there is not one who has left more than a cloud of words behind him.’ ‘Nor did the rogue I mention,’ said Saxon. ‘There was another, Van Helstatt, who was a man of learning, and cast horoscopes in consideration of some small fee or honorarium. I have never met so wise a man, for he would talk of the planets and constellations as though he kept them all in his own backyard. He made no more of a comet than if it were a mouldy china orange, and he explained their nature to us, saying that they were but common stars which had had a hole knocked in them, so that their insides or viscera protruded. He was indeed a philosopher!’ ‘And did you ever put his skill to the test?’ asked one of the officers, with a smile. ‘Not I, forsooth, for I have ever kept myself clear of black magic or diablerie of the sort. My comrade Pierce Scotton, who was an Oberst in the Imperial cavalry brigade, did pay him a rose noble to have his future expounded. If I remember aright, the stars said that he was over-fond of wine and women--he had a wicked eye and a nose like a carbuncle. ‘They foretold also that he would attain a marshal’s baton and die at a ripe age, which might well have come true had he not been unhorsed a month later at Ober-Graustock, and slain by the hoofs of his own troop. Neither the planets nor even the experienced farrier of the regiment could have told that the brute would have foundered so completely.’
