Book 5
1.1
The Greeks who say that the Peloponnesus has five, and only five, divisions must agree that Arcadia contains both Arcadians and Eleans, that the second division belongs to the Achaeans, and the remaining three to the Dorians. Of the races dwelling in Peloponnesus the Arcadians and Achaeans are aborigines. When the Achaeans were driven from their land by the Dorians, they did not retire from Peloponnesus, but they cast out the Ionians and occupied the land called of old Aegialus, but now called Achaea from these Achaeans. The Arcadians, on the other hand, have from the beginning to to the present time continued in possession of their own country.
1.2
The rest of Peloponnesus belongs to immigrants. The modern Corinthians are the latest inhabitants of Peloponnesus, and from my time174 A.D. to the time when they received their land from the Roman Emperor44 B.C. is two hundred and seventeen years. The Dryopians reached the Peloponnesus from Parnassus, the Dorians from Oeta.
1.3
The Eleans we know crossed over from Calydon and Aetolia generally. Their earlier history I found to be as follows. The first to rule in this land, they say, was Aethlius, who was the son of Zeus and of Protogeneia, the daughter of Deucalion, and the father of Endymion.
