and Glauber also entered into the dispute, and attributed the enmity of Father Kircher to spite and jealousy against adepts who had been more successful than himself.
It was also pretended that Gustavus Adolphus transmuted a quantity of quicksilver into pure gold. The learned Borrichius relates, that he saw coins which had been struck of this gold; and Lenglet du Fresnoy deposes to the same circumstance. In the Travels of Monconis the story is told in the following manner: "A merchant of Lubeck, who carried on but little trade, but who knew how to change lead into very good gold, gave the King of Sweden a lingot which he had made, weighing at least one hundred pounds. The king immediately caused it to be coined into ducats; and because he knew positively that its origin was such as had been stated to him, he had his own arms graven upon the one side, and emblematical figures of Mercury and Venus on the other. I (continued Monconis) have one of these ducats in my possession; and was credibly informed that, after the death of the Lubeck merchant, who had never appeared very rich, a sum of no less than one million seven hundred thousand crowns was found in his coffers."[1]
Such stories as these, confidently related by men high in station, tended to keep up the infatuation of the alchymists in every country of Europe. It is astonishing to see the number of works which were written upon the subject during the seventeenth century alone, and the number of clever men who sacrificed themselves to the delusion. Gabriel de Castaigne, a monk of the order of St. Francis, attracted so much notice in the reign of Louis XIII., that that monarch secured him in his household, and made him his Grand Almoner. He pretended to find the elixir of life, and Louis expected by his means to have enjoyed the crown for a century. Van Helmont also pretended to have once performed with success the process of transmuting quicksilver, and was in consequence invited by the Emperor Rudolph II. to fix his residence at the court of Vienna. Glauber, the inventor of the salts which still bear his name, and who practised as a physician at Amsterdam about the middle of the seventeenth century, established a public school in that city for the study of alchymy, and gave lectures himself upon the science. John Joachim Becher of Spire acquired great reputation at the same period, and was convinced that much gold might be made out of flint-stones by a peculiar process, and the aid of that grand and incomprehensible substance the philosopher's stone. He made a proposition to the Emperor Leopold of Austria to aid him in these experiments; but the hope of success was too remote, and the present expense too great, to tempt that mon-
