Pythias, also known as Pythias the Elder, was the adopted daughter of Hermias, ruler of the cities Assos and Atarneus on the Anatolian coast opposite the island of Lesbos. She was also Aristotle's first wife. Hermias was an enemy of Persia and allied with Macedonia. In his will, Aristotle ordered that he be buried next to his wife. From his wording, it is known that Pythias was already dead by the time he wrote his will.
