There is a book, “Heavenly Intrigue” that argues that Tycho likely died of mercury poisoning administered by Kepler. Tycho, besides running an observatory in Prague, had a medical shop, where he formulated mercury compounds to treat a disease he contracted while a student, around the same time he lost his nose in a sword fight. (He was a nobleman student and had a chaperon, who was probably as drunk and whore-infested as he was.)
The formulary produced various mercury compounds in the process, some of which were known to be toxic. Kepler certainly had means, motive and opportunity. No one benefited from Tycho’s very opportune death as much as Kepler, for whom it was a godsend, both professionally and financially.
"How does he smell?"
They mixed mercury with iodine and called it merthiolate. I had my hand soaked in in every day over a 2 week period to treat a splinter that went all the way through my palm. The company doctor didn’t stitch it up after removing the splinter and squeezing out the “white stuff” until he was finished with the mercury treatment. Remember company doctors? Obamacare will bring them back, I’m sure. Med students who had “C” average in school.
Apparently, some idiot just wanted to make a splash about Tycho Brahe.
The scientists, led by Dr Jens Vellev, analyzed Tycho’s beard hair once again. The team reported in November 2012 that not only was there not enough mercury present to substantiate murder, but that there were no lethal levels of any poisons present. The team’s conclusions was that “it is impossible that Tycho Brahe could have been murdered.”
