On the death of Alexander in 323, when anti-Macedonian sentiment was strong in Athens, Aristotle turned his school over to Theophrastus and went to live in Chalcis on the island of Euboea, where he died in 322. Later biographers say he had thin legs, was partially bald, liked to wear rings, and spoke with a lisp. He was married, had one daughter, and after his wife’s death fathered a son by a concubine.
