History of the Peloponnesian War

The Argives not so much for the league as for their enmity against the Lacedaemonians and their present particular spleen, followed the Athenians to the war, though Ionic, against Dorians. And the Mantineans and other Arcadian mercenaries went with them as men accustomer ever to invade the enemy shewed them; and now for gain had for enemies, as much as any, those other Arcadians which went thither with the Corinthians. The Cretans and Aetolians were all mercenary; and it fell out that the Cretans, who together with the Rhodians were founders of Gela, not only took not part with their colony, but fought against it willingly for their hire. And some Acarnanians also went with them for gain;

but most of them went as confederates, in love to Demosthenes and for good will to the state of Athens. And thus many within the bound of the Ionian gulf.

Then of Italians, fallen into the same necessity of seditious times, there went with them to this war the Thurians and Metapontians; of Greek Sicilians, the Naxians and Catanaeans. Of barbarian, the Egestaeans, who also drew with them the most of those Greek Sicilians. Without Sicily, there went with them some Tuscans, upon quarrels between them and the Syracusians, and some Iapygian mercenaries. These were the nations that followed the army of the Athenians.

On the other side, there opposed them on the part of the Syracusians, the Camarinaeans their borderers; and beyond them again the Geloans;

and then (the Agrigentines not stirring) beyond them again the same way, the Selinuntians. These inhabit the part of Sicily that lieth opposite to Afric. Then the Himeraeans, on the side that lieth on the Tyrrhene sea, where they are the only Grecians inhabiting, and only aided them.
