Busardier
An Encyclopaedia of Occultism (1920)
An alchemist of whom few particulars are on record. He lived at Prague with a noble Courtier. Falling sick and feeling the approach of death, he sent a letter to his friend Richtausen, at Vienna, asking him to come and stay with him during his last moments. Richtausen set out at once but on arriving at Prague found that Busardier was dead. On inquiring if the adept had left anything behind him the steward of the nobleman with whom he had lived stated that only some powder had been left which the nobleman desired to preserve. Richtausen by some means got possession of the powder and took his departure. On discovering this the nobleman threatened to hang his steward if he did not recover the powder. The steward surmising that no one but Richtausen could have taken the powder, armed himself and set out in pursuit. Overtaking him on the road he at the point of the pistol, made Richtausen hand over the powder. Richtausen however contrived to abstract a considerable quantity. Richtausen knowing the value of the powder presented himself to the Emperor Ferdinand, himself an alchemist, and gave him a quantity of the powder. The Emperor assisted by his Mine Master, Count Russe, succeeded in converting three pounds of mercury into gold by means of one grain of the powder. The Emperor is said to have commemorated the event by having a medal struck bearing the effigy of Apollo with the caduceus of Mercury and an appropriate motto. Richtausen was ennobled under the title of Baron Chaos . Mr. A. E. Waite in his Lives of the Alchemists states that "Among many transformations performed by the same powder was one by the Elector of Mayence, in 1651. He made projections with all the precautions possible to a learned and skilful philosopher. The powder enclosed in gum tragacanth to retain it effectually, was put into the wax of a taper, which was lighted, the wax being then placed at the bottom of a crucet. These preparations were undertaken by the Elector himself. He poured four ounces of quicksilver on the wax, and put the whole into a fire covered with charcoal above, below and around. Then they began blowing to the utmost, and in about half an hour on removing the coals, they saw that the melted gold was over red, the proper colour being green. The baron said the matter was yet too high and it was necessary to put some silver into it. The Elector took some coins out of his pocket, put them into the melting pot, combined the liquefied silver with the matter in the crucet, and having poured out the whole when in perfect fusion into a lingot, he found after cooling, that it was very fine gold, but rather hard, which was attributed to the lingot. On again melting, it became exceedingly soft and the Master of the Mint declared to His Highness that it was more than twenty-four carats and that he had never seen so fine a quality of the precious metal."
What Has Changed in the Last Century
When the Encyclopaedia of Occultism repeated this tale in 1920, its point was that a single grain of Busardier's powder had turned three pounds of mercury into gold for the Emperor Ferdinand III. Chemistry has since ruled that out absolutely: the number of protons in a nucleus cannot be altered by heating, blowing bellows or mixing powders. Mercury can in fact be turned into gold, but only by nuclear bombardment — first achieved at Harvard in 1941, when neutron-irradiated mercury yielded traces of radioactive gold isotopes, at a cost beyond any economic sense. What has also shifted is the tone: alchemists like Busardier are now studied by historians of science as early experimental chemists rather than filed among occult curiosities, and Waite's 1888 Lives of the Alchemists, quoted at length here, is read as a period document rather than evidence.
