the Turks. In his old age, he became an anchorite near Boston, and wrote twenty-five volumes upon the subject of alchymy, the most important of which is the Duodecim Portarum, already mentioned. Before he died, he seems to have acknowledged that he had misspent his life in this vain study, and requested that all men, when they met with any of his books, would burn them, or afford them no credit, as they had been written merely from his opinion, and not from proof; and that subsequent trial had made manifest to him that they were false and vain.¹⁰

Basil Valentine

    Germany also produced many famous alchymists in the fifteenth century, the chief of whom are Basil Valentine, Bernard of Treves, and the Abbot Trithemius. Basil Valentine was born at Mayence, and was made prior of St. Peter’s, at Erfurt, about the year 1414. It was known, during his life, that he diligently sought the philosopher’s stone, and that he had written some works upon the process of transmutation. They were thought, for many years, to be lost; but were, after his death, discovered enclosed in the stone work of one of the pillars in the Abbey. They were twenty-one in number, and are fully set forth in the third volume of Lenglet’s History of the Hermetic Philosophy. The alchymists asserted, that Heaven itself conspired to bring to light these extraordinary works; and that the pillar in which they were enclosed was miraculously shattered by a thunderbolt; and that, as soon as the manuscripts were liberated, the pillar closed up again of its own accord!

Bernard of Treves

    The life of this philosopher is a remarkable instance of talent and perseverance misapplied. In the search of his chimera nothing could daunt him. Repeated disappointment never diminished his hopes; and, from the age of fourteen to that of eighty-five, he was incessantly employed among the drugs and furnaces of his laboratory, wasting his life with the view of prolonging it, and reducing himself to beggary in the hopes of growing rich.

He was born at either Trèves or Padua, in the year 1406. His father is said by some to have been a physician in the latter city; and by others, to have been Count of the Marches of Trèves, and one of the most wealthy nobles of his country. At all events, whether noble or physician, he was a rich man, and left his son a magnificent estate. At the age of fourteen he first became enamoured of the science of alchymy, and read the Arabian authors in their own language. He himself has left a most interesting record of his labours and wanderings, from which the following particulars are chiefly extracted: — The first book which fell into his hands, was that of the Arabian philosopher, Rhazes, from the reading of which he imagined that he had discovered the means of augmenting gold a hundred fold. For four years he worked in his laboratory, with the book of Rhazes continually before him. At the end of that time, he found that he had spent no less than eight hundred crowns upon his experiment, and had got nothing but fire and smoke for his pains. He now began to lose confidence in Rhazes, and turned to the works of Geber. He studied him assiduously for two years; and, being young, rich, and credulous, was beset by all the chymists of the town, who kindly assisted him in spending his money. He did not lose his faith in Geber, or patience with his hungry assistants, until he had lost two thousand crowns - a very considerable sum in those days.

Among all the crowd of pretended men of science who surrounded him, there was but one as enthusiastic and as disinterested as himself. With this man, who was a monk of the order of St. Francis, he contracted an intimate friendship, and spent nearly all his time. Some obscure treatises of Rupecissa and Sacrobosco having fallen into their hands, they were persuaded, from reading them, that highly rectified spirits of wine was the universal alkahest, or dissolvent, which would aid them greatly in the process of transmutation. They rectified the alcohol thirty times, till they made it so strong as to burst the vessels which contained it. After they had worked three years, and spent three hundred crowns in the liquor, they discovered that they were on the wrong track. They next tried alum and copperas; but the great secret still escaped them. They afterwards imagined that there was a marvellous virtue in all excrement, especially the human, and actually employed more than two years in experimentalizing upon it, with mercury, salt, and molten
