History of the Peloponnesian War

Now for Grecians, first a colony of Chalcideans, under Thucles, their conductor, going from Euboea, built Naxos and the altar of Apollo Archegetes, now standing without the city, upon which the ambassadors employed to the oracles, as often as they launch from Sicily, are accustomed to offer their first sacrifice.

The next year Archias, a man of the Herculean family, carried a colony from Corinth and became founder of Syracuse, where first he drave the Siculi out of that island in which the inner part of the city now standeth, not now environed wholly with the sea as it was then.

And in process of time, when the city also that is without was taken in with a wall, it became a populous city. In the fifth year after the building of Syracuse, Thucles and the Chalcideans, going from Naxos, built Leontium, expelling thence the Siculi, and after that Catana; but they that went to Catana chose Euarchus for their founder.
