J. B. VAN HELMONT.
In the year 1557, at Bois le Duc, in Brabant, John Baptist van Helmont was born of a noble family. He studied at Louvain, and became eminent in mathematics, algebra, the doctrines of Aristotle and Galen, and the medicine of Vopiscus and Plempius. At seventeen he lectured on physics as prælector, and took his degree of medical doctor in 1599. He read Hippocrates and the Greek and Arabian authors before he was twenty-two years old. He then passed ten years in the unsuccessful practice of physic, until he met a Paracelsian chemist, who discovered various chemical medicines to him. He retired thereupon to the castle of Vilvord, near Brussels, and laboured with unremitting diligence in the chemico-experimental analysis of bodies of every class. He passed his life in retirement, and was almost unknown to his neighbours, whom he, nevertheless, attended in illness, without accepting a fee. He declined an invitation and flattering offers from the Emperor and the Elector Palatine, and after writing several tracts, which even at this day are held in considerable estimation, he died in the sixty-seventh year of his age.
This author, so illustrious throughout Europe for his scientific knowledge, and no less celebrated for his noble rank than by the probity of his character, testifies in three different places that he has beheld, and himself performed, transmutation. In his treatise, De Vita Eterna, he declares himself as follows:—“I have seen and I have touched the philosophers’ stone more than once; the colour of it was like saffron in powder, but heavy and shining like pounded glass. I had once given me the fourth part of a grain—I call a grain that which takes six hundred to make an ounce. I made projection therewith, wrapped in paper, upon eight ounces of quicksilver, heated in a crucible, and immediately all the quicksilver, having made a little noise, stopped and congealed into a yellow mass. Having melted it in a strong fire, I found within eleven grains of eight ounces of most pure gold, so that a grain of this powder would have transmuted into very good gold, nineteen thousand one hundred and fifty-six grains of quicksilver.”
Had Helmont possessed the art of making the transmuting powder, his testimony might be open to suspicion. He says, on another occasion, that an adept, after a few days of acquaintance, presented him with half a grain of the powder of projection, with which he transmuted nine ounces of quicksilver into pure gold. He tells us further, that he many times performed a similar operation in the presence of a large company, and always with success. On these grounds he believed in the certainty and in the prodigious resources of the art, citing his acquaintance with an artist who had so much of the red stone as would make gold to the weight of two hundred thousand pounds.
Though ignorant of the nature of this powder of projection, Helmont professed the knowledge of the alcahest, and the methods of preparing medicines of transcendent efficacy by its means.
