When the strength of Samnium had been drained by repeated reverses, there followed the war with the Etruscans; which ended, the Samnites were once more stirred to activity by the coming of Pyrrhus into Italy. When he, too, had been defeated, and sent back to Greece, Rome entered on her first war with the Carthaginians; which was no sooner over than all the Gallic nations on both sides of the Alps combined against the Romans, by whom, in the battle fought between Populonia and Pisa, where now stands the fortress of San Vincenzo, they were at last routed with tremendous slaughter. This war ended, for twenty years together the Romans were engaged in no contest of importance, their only adversaries being the Ligurians, and the remnant of the Gallic tribes who occupied Lombardy; and on this footing things continued down to the second Carthaginian war, which for sixteen years kept the whole of Italy in a blaze. This too being brought to a most glorious termination, there followed the Macedonian war, at the close of which succeeded the war with Antiochus and Asia. These subdued, there remained not in the whole world, king or people who either singly or together could withstand the power of Rome. But even before this last victory, any one observing the order of these wars, and the method in which they were conducted, must have recognized not only the good fortune of the Romans, but also their extraordinary valour and prudence. And were any one to search for the causes of this good fortune, he would have little difficulty in finding them, since nothing is more certain than that when a potentate has attained so great a reputation that every neighbouring prince or people is afraid to engage him single-handed, and stands in awe of him, none will ever venture to attack him, unless driven to do so by necessity; so that it will almost rest on his will to make war as he likes on any of his neighbours, while he studiously maintains peace with the rest; who, on their part, whether through fear of his power, or deceived by the methods he takes to dull their vigilance, are easily kept quiet. Distant powers, in the mean time, who have no intercourse with either, treat the matter as too remote to concern them in any way; and abiding in this error until the conflagration approaches their own doors, on its arrival have no resource for its extinction, save in their own strength, which, as their enemy has by that time become exceedingly powerful, no longer suffices.
