The Veneti were an Indo-European people who inhabited north-eastern Italy, in an area corresponding to the modern-day region of the Veneto, Friuli, and Trentino. By the 4th century BC the Veneti had been so Celticized that Polybius wrote that the Veneti of the 2nd century BC were identical to the Gauls except for language. The Greek historian Strabo (64 BC–AD 24), on the other hand, conjectured that the Adriatic Veneti were descendant from Celts, who in turn were related to later Celtic tribe of the same name who lived on the Armorican coast and fought against Julius Caesar. He further suggested that the identification of the Adriatic Veneti with the Paphlagonian Enetoi led by Antenor — which he attributes to Sophocles (496–406 BC) — was a mistake due to the similarity of the names.
