DENIS ZACHAIRE.

It appears that the true name of this persevering and indefatigable seeker after the end and truth of alchemy has not in reality come down to us, that which is placed at the head of his Opusculum Chimicum being simply pseudonymous. It is to this little work that we are indebted for one of the most singular histories in the annals of the Hermetic art.

Denis Zachaire was born of a noble family, in an unmentioned part of Guienne, during the year 1510. He was sent, as a youth, to Bordeaux, under the care of a tutor, to prosecute the study of philosophy and belles lettres. His preceptor, however, had a passion for alchemy, and inoculated his pupil with the fatal fever of the sages. They speedily abandoned the common academical courses for the thorny pathways of the magnum opus, and Denis, in particular, devoted himself to the assiduous compilation of a vast volume of Hermetic receipts, indicating a thousand processes, with a thousand various materials, for the successful manufacture of gold. From Bordeaux he proceeded to Toulouse, still in the society of his tutor, and for the ostensible study of law, but in reality for the experimental practice of alchemy. Two hundred crowns with which they were supplied for their maintenance during the next two years were speedily expended in the purchase of furnaces, instruments, and drugs, for the literal execution of the processes contained in the books of the adepts.

“Before the end of the year,” as he himself informs us, “my two hundred crowns were gone in smoke, and my tutor died of a fever he took in summer from his close attention to the furnace, which he erected in his chamber, and stayed there continually in extreme heat. His death afflicted me much, and still more as my parents refused to supply me with money, except what was just necessary for my support. I was therefore unable to proceed in my grand work.

“To overcome these difficulties I went home in 1535, being of age, to put myself out of guardianship; and I disposed of some of my property for four hundred crowns. This sum was necessary to execute a process which was given me in Toulouse, by an Italian, who said he saw it proved. I kept him living with me, to see the end of his process.

“We dissolved gold and silver in various sorts of strong waters, but it was all in vain; we did not recover from the solution one half of the gold and silver which we had put into it. My four hundred crowns were reduced to two hundred and thirty, of which I gave twenty to the Italian, to proceed to Milan, where, he said, the author of the process lived, and whence he would return with his explanations. I remained at Toulouse all the winter, awaiting him, and I might have tarried there still, as I never have heard of him since.

“In the ensuing summer the city being visited by the plague, I went to Cahors, and there continued for six months. I did not lose sight of my work, and became acquainted with an old man who was called the philosopher, a name given in the country to any one of superior information. I communicated to him my practices and asked his advice. He mentioned ten or twelve processes which he thought better than others. I returned to Toulouse when the plague ceased, and renewed my labours accordingly. The only consequence was that my money was all spent, except one hundred and seventy crowns. To continue my operations with more certainty, I made acquaintance with an abbé, who dwelt in the neighbourhood of this city. He was taken with a passion for the same pursuit as myself, and he informed me that one of his friends, who lived with Cardinal Armanac, had sent him a process from Rome which he believed genuine, but it would cost two hundred crowns. I agreed to furnish one half of this sum, and he gave the rest, so we began to work together. Our process required a large supply of spirits of wine. I purchased a cask of excellent wine, from which I drew the spirit and rectified it many times. We took two pounds weight of it and half a pound weight of gold, which we had calcined for a month. These were included in a pelican and placed in a furnace. This work lasted a year, but, not to remain idle, we made some other experiments to amuse ourselves, and from which we expected to draw sufficient profit to pay the cost of our great work.

“The year 1537 passed over without any change appearing in the subject of our labours. We might have remained through our whole lives in the same state, for we should have known that the perfect metals are unaltered by vegetable or animal substances. We took out our powder and made projection upon hot quicksilver, but it was in vain! Judge then of our grief, especially as the abbé had notified to all his monks that they would have to melt the lead cistern of their house in order that he might convert it into gold as soon as our operations were finished.

“My bad success could not make me desist. I again raised four hundred crowns on my property; the abbé did the same, and I set out for Paris, a city containing more alchemists than any other in the world. I resolved to remain there as long as the eight hundred crowns lasted, or until I succeeded in my object. This journey drew on me the displeasure of my relations, and the censure of my friends, who imagined I was a studious lawyer. However, I made them believe that the design of my sojourn in Paris was the purchase of a situation in the law courts.

“After travelling for fifteen days I arrived at Paris in January 1539. I remained a month almost unknown, but no sooner had I visited the furnace makers and conversed with some amateurs than I became acquainted with more than a hundred artists, who were all at work in different ways. Some laboured to extract the mercury of metals and afterwards to fix it. A variety of systems were held by others, and scarcely a day passed in which some of them did not visit me, even on Sundays and the most sacred festivals of the Church, to hear what I had done.
