History of the Peloponnesian War

Besides, most of the Echinades islands lie opposite to Oeniadae at no great distance from the mouths of the Achelous, so that the river, which is large, keeps making fresh deposits of silt, and some of the islands have already become part of the mainland, and probably this will happen to all of them in no great while.

For the stream is wide and deep and turbid, and the islands are close together and serve to bind to one another the bars as they are formed, preventing them from being broken up, since the islands lie, not in line, but irregularly, and do not allow straight channels for the water into the open sea. These islands are uninhabited and not large.

There is a story that when Alemaeon son of Amphiaraus was a wanderer after the murder of his mother,[*](Eriphyle.) Apollo directed him by oracle to inhabit this land, intimating that he would have no release from his fears until he should find and settle in a country which at the time he killed his mother had not yet been seen by the sun, and was not even land then, for all the rest of the earth had been polluted by him.
