History of the Peloponnesian War

Of the Italiots, there were the Thurians and Metapontines, dragged into the quarrel by the stern necessities of a time of revolution; of the Siceliots, the Naxians and the Catanians; and of the barbarians, the Egestaeans, who called in the Athenians, most of the Sicels, and outside Sicily some Tyrrhenian enemies of Syracuse and Iapygian mercenaries.

Such were the peoples serving with the Athenians. Against these the Syracusans had the Camarinaeans their neighbors, the Geolans who live next them, and then passing over the neutral Agrigentines, the Selinuntines settled on the farther side of the island.
