History of the Peloponnesian War

With respect to their towns, later on, at an era of increased facilities of navigation and a greater supply of capital, we find the shores becoming the site of walled towns, and the isthmuses being occupied for the purposes of commerce, and defence against a neighbor. But the old towns, on account of the great prevalence of piracy, were built away from the sea, whether on the islands or the continent, and still remain in their old sites. For the pirates used to plunder one another, and indeed all coast populations, whether seafaring or not.

The islanders, too, were great pirates. These islanders were Carians and Phoenicians, by whom most of the islands were colonized, as was proved by the following fact. During the purification of Delos by Athens in this war all the graves in the island were taken up, and it was found that above half their inmates were Carians: they were identified by the fashion of the arms buried with them, and by the method of interment, which was the same as the Carians still follow.

But as soon as Minos had formed his navy, communication by sea became easier, as he colonized most of the islands, and thus expelled the malefactors.

The coast populations now began to apply themselves more closely to the acquisition of wealth, and their life became more settled; some even began to build themselves walls on the strength of their newly-acquired riches. For the love of gain would reconcile the weaker to the dominion of the stronger, and the possession of capital enabled the more powerful to reduce the smaller towns to subjection.

And it was at a somewhat later stage of this development that they went on the expedition against Troy.

What enabled Agamemnon to raise the armament was more, in my opinion, his superiority in strength, than the oaths of Tyndareus, which bound the Suitors to follow him.
