Extraordinary Popular Delusions And The Madness Of Crowds

Chapter 46 - The Cosmopolite

Many disputes have arisen as to the real name of the alchymist who wrote several works under the above designation. The general opinion is that he was a Scotsman, named Seton; and that by a fate very common to alchymists, who boasted too loudly of their powers of transmutation, he ended his days miserably in a dungeon, into which he was thrown by a German potentate until he made a million of gold to pay his ransom. By some he has been confounded with Michael Sendivog, or Sendivogius, a Pole, a professor of the same art, who made a great noise in Europe at the commencement of the seventeenth century. Lenglet du Fresnoy, who is in general well-informed with respect to the alchymists, inclines to the belief that these personages were distinct; and gives the following particulars of the Cosmopolite, extracted from George Morhoff, in his "Epistola ad Langelottum," and other writers.

About the year 1600, one Jacob Haussen, a Dutch pilot, was shipwrecked on the coast of Scotland. A gentleman, named Alexander Seton, put off in a boat, and saved him from drowning, and afterwards entertained him hospitably for many weeks at his house on the shore. Haussen saw that he was addicted to the pursuits of chemistry, but no conversation on the subject passed between them at the time. About a year and a half afterwards, Haussen being then at home at Enkhuysen, in Holland, received a visit from his former host. He endeavoured to repay the kindness that had been shown him; and so great a friendship arose between them, that Seton, on his departure, offered to make him acquainted with the great secret of the philosopher's stone. In his presence the Scotsman transmuted a great quantity of base metal into pure gold, and gave it him as a mark of his esteem. Seton then took leave of his friend, and travelled into Germany. At Dresden he made no secret of his wonderful powers; having, it is said, performed transmutation successfully before a great assemblage of the learned men of that city. The circumstance coming to the ears of the Duke or Elector of Saxony, he gave orders for the arrest of the alchymist. He caused him to be imprisoned in a high tower, and set a guard of forty men to watch that he did not escape, and that no strangers were admitted to his presence. The unfortunate Seton received several visits from the Elector, who used every art of persuasion to make him divulge his secret. Seton obstinately refused either to communicate his secret, or to make any gold for the tyrant; on which he was stretched upon the rack, to see if the argument of torture would render him more tractable. The result was still the same, - neither hope of reward nor fear of anguish could shake him. For several months he remained in prison, subjected alternately to a sedative and a violent regimen, till his health broke, and he wasted away almost to a skeleton.

There happened at that time to be in Dresden a learned Pole, named Michael Sendivogius, who had wasted a good deal of his time and substance in the unprofitable pursuits of alchymy. He was touched with pity for the hard fate, and admiration for the intrepidity of Seton; and determined, if possible, to aid him in escaping from the clutch of his oppressor. He requested the Elector's permission to see the alchymist, and obtained it with some difficulty. He found him in a state of great wretchedness, -- shut up from the light of day in a noisome dungeon, and with no better couch or fare than those allotted to the worst of criminals. Seton listened eagerly to the proposal of escape, and promised the generous Pole that he would make him richer than an Eastern monarch if by his means he were liberated. Sendivogius immediately commenced operations. He sold some property which he possessed near Cracow, and with the proceeds led a merry life at Dresden. He gave the most elegant suppers, to which he regularly invited the officers of the guard, and especially those who did duty at the prison of the alchymist. He insinuated himself at last into their confidence, and obtained free ingress to his friend as often as he pleased; pretending that he was using his utmost endeavours to conquer his obstinacy and worm his secret out of him. When their project was ripe, a day was fixed upon for the grand attempt; and Sendivogius was ready with a postchariot to convey him with all speed into Poland. By drugging some wine which he presented to the guards of the prison, he rendered them so drowsy that he easily found means to scale a wall unobserved, with Seton, and effect his escape. Seton's wife was in the chariot awaiting him, having safely in her possession a small packet of a black powder, which was, in fact, the philosopher's stone, or ingredient for the transmutation of iron and copper into gold. They all arrived in safety at Cracow; but the frame of Seton was so wasted by torture of body and starvation, to say nothing of the anguish of mind he had endured, that he did not long survive. He died in Cracow in 1603 or 1604, and was buried under the cathedral church of that city. Such is the story related of the author of the various works which bear the name of the Cosmopolite. A list of them may be found in the third volume of the "History of the Hermetic Philosophy."
