Fearing anti-Macedonian sentiment in Athens after Alexander's death, Aristotle fled to the island of Euboia in 323 B.C. He died there a year later. The tides in the narrows between Euboia and the Greek mainland ebb and flow in a unique way. This fact allowed the myth to take hold that Aristotle flung himself into the sea in frustration at his inability to explain the unique pattern of the tides here. The available evidence, however, indicates that he in fact died of a stomach illness.
