The different parts of Transpadana are inhabited by the Heneti and the Istrii as far as Pola; above the Heneti, by the Carni, the Cenomani, the Medoaci, and the Symbri.[1637] These nations were formerly at enmity with the Romans, but the Cenomani and Heneti allied themselves with that nation, both prior to the expedition of Hannibal, when they waged war with the Boii and Symbrii,[1637] and also after that time. 10. Cispadana comprehends all that country enclosed [CAS. 216] between the Apennines and the Alps as far as Genoa and Vada-Sabatorum.[1638] The greater part was inhabited by the Boii, the Ligurians, the Senones, and Gæsatæ; but after the depopulation of the Boii, and the destruction of the Gæsatæ and Senones, the Ligurian tribes and the Roman colonies alone remained. The nation of the Ombrici[1639] and certain of the Tyrrheni are also mixed amongst the Romans. These two nations, before the aggrandizement of the Romans, had some disputes with each other concerning precedence. Having only the river Tiber between, it was easy to commence war upon each other; and if the one sent out an expedition against any nation, it was the ambition of the other to enter the same country with an equal force. Thus, the Tyrrheni, having organized a successful expedition against the barbarians [dwelling in the countries] about the Po, but having speedily lost again through their luxury [all they had acquired], the Ombrici made war upon those who had driven them out. Disputes arose between the Tyrrheni and Ombrici concerning the right of possessing these places, and both nations founded many colonies; those, however, of the Ombrici were most numerous, as they were nearest to the spot. When the Romans gained the dominion, they sent out colonies to different parts, but preserved those which had been formerly planted by their predecessors. And although now they are all Romans, they are not the less distinguished, some by the names of Ombri and Tyrrheni, others by those of Heneti, Ligurians, and Insubri.
