of philosophy:— First of all, he maintained that the contemplation of the perfection of the Deity sufficed to procure all wisdom and knowledge; that the Bible was the key to the theory of all diseases, and that it was necessary to search into the Apocalypse to know the signification of magic medicine. The man who blindly obeyed the will of God, and who succeeded in identifying himself with the celestial intelligences, possessed the philosopher’s stone — he could cure all diseases, and prolong life to as many centuries as he pleased; it being by the very same means that Adam and the antediluvian patriarchs prolonged theirs. Life was an emanation from the stars — the sun governed the heart, and the moon the brain. Jupiter governed the liver, Saturn the gall, Mercury the lungs, Mars the bile, and Venus the loins. In the stomach of every human being there dwelt a demon, or intelligence, that was a sort of alchymist in his way, and mixed, in their due proportions, in his crucible, the various aliments that were sent into that grand laboratory the belly.¹³ He was proud of the title of magician, and boasted that he kept up a regular correspondence with Galen from hell; and that he often summoned Avicenna from the same regions to dispute with him on the false notions he had promulgated respecting alchymy, and especially regarding potable gold and the elixir of life. He imagined that gold could cure ossification of the heart, and, in fact, all diseases, if it were gold which had been transmuted from an inferior metal by means of the philosopher’s stone, and if it were applied under certain conjunctions of the planets. The mere list of the works in which he advances these frantic imaginings, which he called a doctrine, would occupy several pages.

George Agricola

    This alchymist was born in the province of Misnia, in 1494. His real name was Bauer, meaning a husbandman, which, in accordance with the common fashion of his age, he Latinized into Agricola. From his early youth, he delighted in the visions of the hermetic science. Ere he was sixteen, he longed for the great elixir which was to make him live for seven hundred years, and for the stone which was to procure him wealth to cheer him in his multiplicity of days. He published a small treatise upon the subject at Cologne, in 1531, which obtained him the patronage of the celebrated Maurice, Duke of Saxony. After practising for some years as a physician at Joachimsthal, in Bohemia, he was employed by Maurice as superintendent of the silver mines of Chemnitz. He led a happy life among the miners, making various experiments in alchymy while deep in the bowels of the earth. He acquired a great knowledge of metals, and gradually got rid of his extravagant notions about the philosopher’s stone. The miners had no faith in alchymy; and they converted him to their way of thinking, not only in that but in other respects. From their legends, he became firmly convinced that the bowels of the earth were inhabited by good and evil spirits, and that firedamp and other explosions sprang from no other causes than the mischievous propensities of the latter. He died in the year 1555, leaving behind him the reputation of a very able and intelligent man.

Denis Zachaire

    Autobiography, written by a wise man who was once a fool, is not only the most instructive, but the most delightful of reading. Denis Zachaire, an alchymist of the sixteenth century, has performed this task, and left a record of his folly and infatuation in pursuit of the philosopher’s stone, which well repays perusal. He was born in the year 1510, of an ancient family in Guienne, and was early sent to the university of Bordeaux, under the care of a tutor to direct his studies. Unfortunately, his tutor was a searcher for the grand elixir, and soon rendered his pupil as mad as himself upon the subject. With this introduction, we will allow Denis Zachaire to speak for himself, and continue his narrative in his own words :—“ I received from home,” says he, “the sum of two hundred crowns for the expenses of myself and master; but before the end of the year, all our money went away in the smoke of our furnaces. My master, at the same time, died of a fever, brought on by the parching heat of our laboratory, from which he seldom or never stirred, and which was scarcely less hot than the arsenal of Venice. His death was the more unfortunate for me, as my parents took the opportunity of reducing my allowance, and sending me only sufficient for my board and lodging, instead of the sum I required to continue my operations in alchymy.

“To meet this difficulty and get out of leading-strings, I returned home at the age of twenty-five, and mortgaged part of my property for four hundred crowns. This sum was necessary to perform an operation of the
