 On the other hand, it seems clear from the account of the settlement at Metapontum, that the territory of Siris was at that time still unoccupied by any Greek colony.We may therefore probably place the date of the Ionian settlement at Siris between 690 and 660 BCE.We are told that the Ionic colonists gave to the city the name of Polieum; but the appellation of Siris, which it derived from the river, and which seems to have been often given to the whole district (, used as equivalent to ), evidently prevailed, and is the only one met with in common use.
