History of the Peloponnesian War

After this, the Ionians, in the times of Cyrus, first king of the Persians, and of his son Cambyses, got together a great navy, and making war on Cyrus, obtained for a time the dominion of that part of the sea that lieth on their own coast. Also Polycrates, who in the time of Cambyses tyrannised in Samos, had a strong navy wherewith he subdued divers of the islands; and amongst the rest having won Rhenea, he consecrated the same to Apollo of Delos. The Phocaeans likewise, when they were building the city of Marseilles, overcame the Carthaginians in a fight at sea.

These were the greatest navies extant. And yet even these, though many ages after the time of Troy, consisted, as it seems, but of a few galleys, and were made up with vessels of fifty oars and with long boats, as well as those of former times.

And it was but a little before the Medan war and death of Darius, successor of Cambyses in the kingdom of Persia, that the tyrants of Sicily and the Corcyraeans had of galleys any number. For these last were the only navies worth speaking of in all Greece before the invasion of the Medes.
