Halliwell mentions in passing a series of anecdotes that tell of famous characters from antiquity who laughed so much that they died. Zeuxis, the famous fourth-century Greek painter, is one. He collapsed, it is said, after looking at his own painting of an elderly woman.

[O]ne determined Roman agelast (“non-laugher”), the elder Marcus Crassus … is reputed to have cracked up just once in his lifetime. It was after he had seen a donkey eating thistles. “Thistles are like lettuce to the lips of a donkey”, he mused (quoting a well-known ancient proverb) – and laughed.
