Tychonis Brahe Dani Opera Omnia,
10:3/Rosen, 312, 313. Quoted in Ferguson,
Tycho and Kepler,
p. 283. After Tycho's funeral, the talk on the streets in Prague proposed that he had been poisoned. This was not entirely unreasonable, since some of his symptoms could have been caused by an overdose of heavy metals. Certainly, Tycho had his enemies at the court, since many feared that as a Lutheran he had far too much influence over the unfortunate Rudolf. The Catholic council was not above a bit of murder, to be sure. However, the most likely case is that Tycho, who practiced homeopathic medicine, which was considered part of an astrologer's overall function, overdosed on some of his own medicine. Many of the remedies he concocted were high in mercury, and if his bladder infection proved stubborn
against his cures, he may have simply kept taking them in larger doses until he poisoned himself.
Forensic studies of Tycho's DNA, found in a small box containing bits of Tycho's beard and a small piece of his shroud, were done in 1991. Any heavy metals in the body would be present in the hair strands, and because hair grows at a regular rate, concentrations could be graphed over time by taking different points on the strand of hair as time points. Tycho's beard showed a high concentration of lead, which meant he could have died from lead poisoning, but that by itself was not all that conclusive, because many people who lived in cities at the time may well have had high lead concentrations for environmental reasons, most notably the use of lead in plumbing. There was a little arsenic in the hair, but there was a much larger than normal concentration of mercury. Also uremia may be caused by mercury poisoning.
In 1996 another test was conducted, using the PIXW (Particle Induced X-ray Emission) method on a piece of Tycho's beard that included some of the root. This test showed that mercury had been ingested shortly before Tycho's death, which meant that he probably died of a mercury overdose. More than likely Tycho did this to himself in an attempt to cure the urinary disorder, perhaps prostatic hypertrophy (or possibly bladder stones), that had been troubling him. It was this failed cure that caused the uremia that killed him. See Aase R. Jacobsen,

My original term for “religious concessions” was “religious liberty,” which, on reflection, was anachronistic. Religious liberty was hard to come by at the time. Religious groups, Catholic to Protestant, Protestant to Catholic, Protestant to Protestant, that wanted liberty for themselves rarely offered it to others. Religious toleration was yet an undiscovered idea and was problematic for that time. One historical prejudice that has come down to us is that intolerance was a Catholic practice and tolerance was Protestant, but the historical record does not bear that out. In the seventeenth century, religious intolerance was the game everywhere.

There are several possibilities for the death of Frau Meyer. The potion that Katharina Kepler gave to her may well have been tainted not on purpose, but out of mishandling. Perhaps she died of botulism toxin. Or possibly she died of one of the numerous pestilences that swept through the region, and the two illnesses, hers and Beutelsbacher's, were not connected. Katharina Kepler told the jury that Beutelsbacher tried to jump over a ditch that day and possibly broke his leg, and that was why he went lame. Why an old school chum of Johannes's would want to accuse his mother of witchcraft is lost to us. He may have resented Johannes's success or may have actually connected his illness with the death of Bastian Meyer's wife. He may also have been lying.
