A bare mention must suffice for Gela, founded from Rhodes and Crete nearly half a century after Syracuse, and the more famous Agrigentum, a colony from Gela, and next to Syracuse the greatest city in Sicily. These played no part in the struggle with Athens; but Selinus and Camarina, the two remaining Dorian cities of southern Sicily, will occupy an important place in the following narrative. Thus the whole coast districts on southern and eastern Sicily were held by opulent and flourishing Greek cities. On the north was Himera, an Ionic colony, and the scene of Gelo's great victory over Carthage; while the western and north-western district was divided between the Phoenicians and the Elymi, a people of unknown origin, whose chief seats were at Eryx and Egesta. The inland parts were held, in the west, by the Sicans, who are believed to have come from Spain, and in the east by the Sicels, a people of Latin race, who gave their name to the island. II Since the fourth year of the Peloponnesian War, Athens had been meddling in the affairs of Sicily, under pretence of aiding the Ionian cities, who dreaded the encroaching ambition of Syracuse. That these fears were not unfounded was proved when, a few years afterwards, the Syracusans expelled the commons of Leontini, and took possession of their territory. The Leontine exiles sought refuge at Athens, but their appeal for help remained for a time unanswered, as the Athenians were then fully occupied in Greece. But six years after the conclusion of the Peace of Nicias, an appeal came to Athens from a remote corner of Sicily, which stimulated the Leontine exiles to fresh efforts, and led to most important results. Between the Greeks of Selinus and the Elymians of Egesta there was a long-standing quarrel, and in a war which had recently broken out the Egestaeans were reduced to severe straits by the combined forces of Selinus and Syracuse. In their distress they turned to Athens for help, and envoys were sent to plead their cause before the Athenian assembly. In aiding Egesta, argued the envoys, Athens would be serving her own interests; for if the Syracusans were not speedily checked in their aggressions, they would soon make themselves masters of the whole of Sicily, and in that case they could bring such an accession of strength to the enemies of Athens in Greece as to make them irresistible. They had good reason, therefore, to take sides against the enemies of Egesta, and the more so as the Egestaeans promised to defray all the expenses of the war.
