Of the Gauls, there were in the north of Italy the Boians and Insubrians; the former, south of the Po in the Romagna; the latter, in the territory of Milan, and in the plain between Bergamo and Brescia; yet these two cantons were not Gallic, but probably Rhætian, of Etruscan extraction. Between the Insubrians and Venetians dwelt the Cenomanians, between Milan and Mantua; these had placed themselves under the protection of the Romans. On the other side of the Alps, there was a great movement, and the Boians could now induce Transalpine volunteers to come over: these negociations caused the Romans great alarm. Several years now passed away: at length, eight years after the Flaminian law, a countless horde made its appearance, and the war broke out in 527. This war is memorable in history for the immense preparations of the Romans; it was a swarm which they had to deal with, very much as in the time of the Cimbrians. Among the tribes which were in arms, there were also Tauriscans. These, on other occasions, we meet with only in Carniola: whether in those days they were also in Helvetia, we must leave undecided. The Romans called forth a general levy throughout all Italy: the allies obeyed very readily, as they looked forward with dismay to an invasion of the Gauls. The Romans opposed to the enemy an army on the common road of the Gauls near Rimini, which was under the consul L. Æmilius, and another, a prætorian one, in Etruria. At the same time, the consul C. Atilius had gone with a fleet and army to Sardinia, as the Sards had revolted. In the neighbourhood of Rome, there was a reserve: all the Italian nations were in marching order. Polybius here gives a list, from which we find that he had not a clear insight into the subject. The numbers are wrongly written, and all attempts to sum them up are fruitless: several peoples are not named at all. I believe that Fabius wrote in a hurry, when he stated the numbers at 800,000 foot and 80,000 horse. In short, this list is of no use; and at any rate, one ought never to draw from this census such conclusions with regard to the population of the ancient world, as was done in the dispute between Hume and Wallace; for although Hume keeps on the side of common sense, yet he takes the matter too lightly. Perhaps something has slipped out in Polybius.
