Callistratus (gr. Kallistratos) the son of Empedus, is mentioned by Pausanias as the commander of a body of Athenian cavalry in Sicily during the expedition of Nicias. When his countrymen were nearly cut to pieces at the river Assinarus, 413 BC, Callistratus forced his way through the enemy and led his men safe to Catana. Thence returning to Syracuse, he attacked those who were plundering the Athenian camp, and fell, selling his life dearly. (Paus. vii. 16; comp. Thuc. vii. 84, 85.)
