From the Guardian (just the ones of interest to us):

1. Heracleitus (540-480 BC)
Heracleitus became such a hater of humanity that he wandered in the mountains and lived on a diet of grass and herbs. But malnutrition gave him dropsy and he returned to the city to seek a cure, asking to be covered in cow dung, which he believed would draw the bad humours out of his body. In the first version of the story, the cow dung is wet and the weeping philosopher drowns; in the second, it is dry and he is baked to death in the Ionian sun.

2. Diogenes (d.320 BC)
Once described as "a Socrates gone mad", Diogenes asked to be buried face down "because after a little time down will be converted into up". He is said to have been nearly 90 when he died, either after eating raw octopus or by committing suicide by holding his breath.

3. Chrysippus (280-207BC)
Perhaps the greatest of the Stoics. There are two stories of his death, both involving alcohol. In the first, he took a draught of sweet wine unmixed with water, was seized with dizziness and died five days later. But the second is even better: after an ass had eaten his figs, he cried out to an old woman, "Now give the ass a drink of pure wine to wash down the figs". Thereupon, he laughed so heartily that he died.


10. Michel Foucault (1926-1984)
Foucault was first hospitalized in June 1984 with the symptoms of a nasty and persistent flu, fatigue, terrible coughing and migraine. "It's like being in a fog," he said. But he carried on working until the end on the second and third volumes of The History of Sexuality, which appeared shortly before his death. Although he was a very early victim of the virus, it seems that Foucault knew that he had Aids. Foucault was fond of reading Seneca towards the end and died on 25 June like a classical philosopher.
