History of the Peloponnesian War

As for cities, such as are of late foundation and since the increase of navigation, inasmuch as they have had since more plenty of riches, have been walled about and built upon the shore, and have taken up isthmi [that is to say, necks of land between sea and sea] both for merchandise and for the better strength against confiners. But the old cities, men having been in those times for the most part infested by thieves, are built farther up, as well in the islands as in the continent. For others also that dwelt on the seaside, though not seamen, yet they molested one another with robberies. And even to these times those people are planted up high in the country.

But these robberies were the exercise especially of the islanders, namely, the Carians and the Phoenicians. For by them were the greatest part of the islands inhabited, a testimony whereof is this. The Athenians when in this present war they hallowed the isle of Delos and had digged up the sepulchres of the dead found that more than half of them were Carians, known so to be both by the armour buried with them and also by their manner of burial at this day.

And when Minos his navy was once afloat, navigators had the sea more free. For he expelled the malefactors out of the islands and in the most of them planted colonies of his own.
