Strabo, Geography

But Hecataeus of Miletus says that the Epeians are a different people from the Eleians; that, at any rate, the Epeians joined Heracles in his expedition against Augeas and helped him to destroy both Augeas and Elis. And he says, further, that Dyme is an Epeian and an Achaean city. However, the early historians say many things that are not true, because they were accustomed to falsehoods on account of the use of myths in their writings; and on this account, too, they do not agree with one another concerning the same things. Yet it is not incredible that the Epeians, even if they were once at variance with the Eleians and belonged to a different race, later became united with the Eleians as the result of prevailing over them, and with them formed one common state; and that they prevailed even as far as Dyme. For although the poet has not named Dyme, it is not unreasonable to suppose that in his time Dyme belonged to the Epeians, and later to the Ionians, or, if not to them, at all events to the Achaeans who took possession of their country. Of the four parts, inside which Buprasium is situated, only Hyrmine and Myrsinus belong to the Eleian country, whereas the remaining two are already on the frontiers of Pisatis, as some writers think.
