History of the Peloponnesian War

After the taking of Illium, certain Trojans, escaping the hands of the Grecians, landed with small boats in Sicily; and having planted themselves on the borders of the Sicanians, both the nations in one were called Elymi; and their cities were Eryx and Egesta. Hard by these came and dwelled also certain Phoceans, who, coming from Troy, were by tempest carried first into Africa and thence into Sicily.

But the Siculi passed out of Italy (for there they inhabited), flying from the Opici, having, as is most likely and as it is reported, observed the strait, and with a fore wind gotten over in boats which they made suddenly on the occasion, or perhaps by some other means. There is at this day a people in Italy called Siculi. And Italy itself got that name after the same manner from a king of Arcadia called Italus.
