Book 7
1.1
The land between Elis and Sicyonia, reaching down to the eastern sea, is now called Achaia after the inhabitants, but of old was called Aegialus and those who lived in it Aegialians. According to the Sicyonians the name is derived from Aegialeus, who was king in what is now Sicyonia; others say that it is from the land, the greater part of which is coast ( aigialos).
1.2
Later on, after the death of Hellen, Xuthus was expelled from Thessaly by the rest of the sons of Hellen, who charged him with having appropriated some of the ancestral property. But he fled to Athens, where he was deemed worthy to wed the daughter of Erechtheus, by whom he had sons, Achaeus and Ion. On the death of Erechtheus Xuthus was appointed judge to decide which of his sons should succeed him. He decided that Cecrops, the eldest of them, should be king, and was accordingly banished from the land by the rest of the sons of Erechtheus.
1.3
He reached Aegialus, made his home there, and there died. Of his sons, Achaeus with the assistance of allies from Aegialus and Athens returned to Thessaly and recovered the throne of his fathers: Ion, while gathering an army against the Aegialians and Selinus their king, received a message from Selinus, who offered to give him in marriage Helice, his only child, as well as to adopt him as his son and successor.
1.4
It so happened that the proposal found favour with Ion, and on the death of Selinus he became king of the Aegialians. He called the city he founded in Aegialus Helice after his wife, and called the inhabitants Ionians after himself. This, however, was not a change of name, but an addition to it, for the folk were named Aegialian Ionians. The original name clung to the land even longer than to the people; for at any rate in the list of the allies of Agamemnon, HomerHom. Il. 2.575 is content to mention the ancient name of the land:Throughout all Aegialus and about wide Helice.Hom. Il. 2.575
