jan 1, 130 BC - Polybius "Histories"

Description:

[ca. 228 BCE] § 2.17.3 The Celts, being close neighbors of the Etruscans and associating much with them, cast covetous eyes on their beautiful country, and on a small pretext, suddenly attacked them with a large army and, expelling them from the plain of the Po, occupied it themselves. 4 The first settlers at the eastern extremity, near the source of the Po, were the Laevi and Lebecii, after them the Insubres, the largest tribe of all, and next these, on the banks of the river, the Cenomani. 5 The part of the plain near the Adriatic had never ceased to be in the possession of another very ancient tribe called the Veneti, differing slightly from the Gauls in customs and costume and speaking another language.

§ 2.17.6 About this people [Veneti] the tragic poets tell many marvelous stories.

§ 2.18.3 but being diverted by an invasion of their own country by the Veneti, they made on this occasion a treaty with the Romans, and evacuating the city, returned home. 4 After this they were occupied by domestic wars, and certain of the neighbouring Alpine tribes, witnessing to what prosperity they had attained in comparison with themselves, frequently gathered to attack them.

§ 2.23.1 The Gaesatae, having collected a richly equipped and formidable force, crossed the Alps, and descended into the plain of the Po in the eighth year after the partition of Picenum. 2 The Insubres and Boii held stoutly to their original purpose; but the Veneti and Cenomani, on the Romans sending an embassy to them, decided to give them their support;

§ 2.24.6 The Romans massed these forces and posted them on the frontier of Etruria under the command of a Praetor. 7 The levy of the Umbrians and Sarsinates inhabiting the Apennines amounted to about twenty thousand, and with these were twenty thousand Veneti and Cenomani. 8 These they stationed on the frontier of Gaul, to invade the territory of the Boii and divert them back from their expedition.
