ACHAIA:

"Crossing the river Larissus, and pursuing the northern coast of Peloponnesus south of the Corinthian Gulf, the traveller would pass into Achaia--a name which designated the narrow strip of level land, and the projecting spurs and declivities between that gulf and the northernmost mountains of the peninsula. ... Achaean cities--twelve in number at least, if not more--divided this long strip of land amongst them, from the mouth of the Larissus and the northwestern Cape Araxus on one side, to the western boundary of the Sikyon territory on the other. According to the accounts of the ancient legends and the belief of Herodotus, this territory had been once occupied by Ionian inhabitants, whom the Achaeans had expelled."
