Tycho Brahe's death was an interesting one:
"The 13th of October 1601 Tycho Brahes was invides together with a nobleman called Minckwitz to a supper at Baron von Rosenberg. Before they sat down at the table, Tycho did not let his water, as he otherwise usually did. During the dinner lots of wine was consumed, and Tycho noticed that his bladder was tense, and he realised that he soon would have to get up. Out of respect for the host, he waited however, but finally he had to get up from the table and get home. But his bladder had been blocked by waiting to long, and he could not let his water. Hard pains followed and for five days, he could not sleep. Thereafter he could let out small amounts of urine, and the patient fell into an uneasy sleep. He also had a strong fever and dizziness. [...] For another five days this state lasted. [...] The following night, the last, Tycho was relatively calm, and no bad dreams worried him during his dizziness.
During his fever fantasies he muttered the words "Ne frustra vixisse videar" over and over (approx. May I not seemed to have lived in vain).
The following day, the 24th of October, the fever dizziness faded, and his conciousness returned. But the sicknes had taken so much of his powers that the end would not last many hours. When he notices his soon coming death, he expressed a wish, that his life's works would honour the lord and gave his sons and his nephew a task to not let anything of it get lost and that they should trust in the help of emperor. [...] "
However recent studies suggest that he died of Mercury poisoning.
