All public records and materials for history, except those engraved on stone, were destroyed in the capture and burning of Rome by the Gauls, so that up to this time Roman “history” is not really worthy of the name. But from this time onward certain official records were preserved, and we gradually pass into an age which may truly be called historical. In detail it will still be questionable, chiefly owing to the tendency of Roman leading families to glorify the deeds of their own ancestors at the expense of truth, and so to hand on false accounts to the age when history first came to be written down. But in the fourth and third centuries B.C. it becomes fairly clear in outline. I said in the last chapter that the Romans were curiously destitute of the imaginative faculty. But no people is entirely without imagination, and it is most interesting to find the Romans using their moderate allowance in inventing the details of noble deeds and honourable services to the State. Provoking as it is to us, and provoking even to the Roman historian Livy himself, who was well aware of it, this habit has its own value as a feature of old Roman life and character. But I must return to the story of the advance of Rome in Italy. It seems clear that after the Gallic invasion the Latins became more and more discontented with Roman policy, which probably aimed at utilising all the resources of the league and at the same time getting complete control of its relations to other powers. We have the text in Greek, preserved by the historian Polybius, of a treaty with Carthage, then the greatest naval power in the Mediterranean, which well illustrates this: the date is 348 B.C. Rome acts for Latium in negotiating this treaty; and Carthage undertook not to molest the Latin cities, _provided that they remained faithful to Rome_; nay, even to restore to the power of the leading city any revolting Latin community that might fall into their hands. This plainly shows that revolt was expected, and a few years later it became general. But in spite of the support of the Campanians in the rich volcanic plain farther south, and indeed of danger so great that it gave rise to another story of the “devotio” of a Roman consul to the infernal deities on behalf of the State, the Latins were completely beaten at the battle of Mount Vesuvius, and the Romans were able so to alter the league as to deprive it of all real claim to be called a federation.
