Nicomachus (Ancient Greek: Νικόμαχος; fl. c. 375 BC) was the father of Aristotle. The Suda states that he was a doctor descended from Nicomachus, son of Machaon the son of Asclepius.[1] Greenhill notes he had another son named Arimnestus, and a daughter named Arimneste, by his wife Phaestis, or Phaestias, who was descended from Asclepius as well. He was a native of Stageira, and the friend and physician of Amyntas III, king of Macedonia, 393–369 BC.[2] Nicomachean Ethics, Aristotle's work on Ethics may have been dedicated to his father. Aristotle's son was also called Nicomachus.
