On the death of Seton, Sendivogius married his widow, hoping to learn from her some of the secrets of her deceased lord in the art of transmutation. The ounce of black powder stood him, however, in better service; for the alchymists say, that by its means he converted great quantities of quicksilver into the purest gold. It is also said that he performed this experiment successfully before the Emperor Rudolph II., at Prague; and that the emperor, to commemorate the circumstance, caused a marble tablet to be affixed to the wall of the room in which it was performed, bearing this inscription, "Faciat hoc quispiam alius, quod fecit Sendivogius Polonus." M. Desnoyers, secretary to the Princess Mary of Gonzaga, Queen of Poland, writing from Warsaw in 1651, says that he saw this tablet, which existed at that time, and was often visited by the curious.

The after-life of Sendivogius is related in a Latin memoir of him by one Brodowski, his steward; and is inserted by Pierre Borel in his Treasure of Gaulish Antiquities. The Emperor Rudolph, according to this authority, was so well pleased with his success, that he made him one of his councillors of state, and invited him to fill a station in the royal household and inhabit the palace. But Sendivogius loved his liberty, and refused to become a courtier. He preferred to reside on his own patrimonial estate of Gravarna, where, for many years, he exercised a princely hospitality. His philosophic powder, which, his steward says, was red, and not black, he kept in a little box of gold; and with one grain of it he could make five hundred ducats, or a thousand rix-dollars. He generally made his projection upon quicksilver. When he travelled, he gave this box to his steward, who hung it round his neck by a gold chain next his skin. But the greatest part of the powder he used to hide in a secret place cut into the step of his chariot. He thought that, if attacked at any time by robbers, they would not search such a place as that. When he anticipated any danger, he would dress himself in his valet's clothes, and, mounting the coach-box, put the valet inside. He was induced to take these precautions, because it was no secret that he possessed the philosopher's stone; and many unprincipled adventurers were on the watch for an opportunity to plunder him. A German prince, whose name Brodowski has not thought fit to chronicle, served him a scurvy trick, which ever afterwards put him on his guard. This prince went on his knees to Sendivogius, and entreated him in the most pressing terms to satisfy his curiosity, by converting some quicksilver into gold before him. Sendivogius, wearied by his importunity, consented, upon a promise of inviolable
