History of the Peloponnesian War

For the Grecians in old time, and such barbarians as in the continent lived near unto the sea or else inhabited the islands after once they began to cross over one to another in ships, became thieves and went abroad under the conduct of their most puissant men, both to enrich themselves and to fetch in maintenance for the weak, and falling upon towns unfortified and scatteringly inhabited, rifled them and made this the best means of their living, being a matter at that time nowhere in disgrace but rather carrying with it something of glory.

This is manifest by some that dwell on the continent, amongst whom, so it be performed nobly, it is still esteemed as an ornament. The same also is proved by some of the ancient poets, who introduce men questioning of such as sail by, on all coasts alike, whether they be thieves or not, as a thing neither scorned by such as were asked nor upbraided by those that were desirous to know.

They also robbed one another within the mainland. And much of Greece useth that old custom, as the Locrians called Ozolae, the Acarnanians, and those of the continent in that quarter, unto this day. Moreover, the fashion of wearing iron remaineth yet with the people of that continent from their old trade of thieving.
