But before the promulgation of the Licinian laws, there were threatenings of greater danger than was to be feared either from Etruscans or Volscians. The Latins and Hernicans, who since the time of Sp. Cassius had fought by the side of Rome in all her border wars, no longer appeared in this position. The inroad of the Gauls had broken up the league. Rome had been reduced to ashes, and was left in miserable weakness. Many of the thirty Latin towns, the names of which occur in the league of Cassius, were so utterly destroyed, that the antiquary in vain seeks for their site in the desolation of the Campagna. But the two important cities of Tibur and Præneste (Tivoli and Palestrina), perched on steep-scarped rocks, defying the rude arts of the invader, had gained strength by the ruin of their neighbours, and appear as independent communities, standing apart from the rest of Latium and from Rome. It was believed that the Prænestines encouraged the Volscians in their inroads, and in 382 B.C. war was declared against them. Some of the Latin cities joined Præneste; others sought protection against her from Rome. In this war even the Tusculans deserted Rome. But after a struggle of five years, the dictator, T. Quinctius, took nine insurgent cities, and blockaded Præneste itself, which capitulated on terms of which we are not informed. Soon after Tusculum also was recovered; and for the present all fear of the Latins subsided. But a few years after the temple of Concord had been erected by old Camillus, fresh alarms arose. The Hernicans gave signs of disquietude. War was declared against them in 362 B.C. Next year came the second inroad of the Gauls, and it was observed with consternation, that this terrible foe occupied the valley of the Anio, and was not molested either by the Latins of Tibur or by the Hernicans. In the year 360 B.C. the _Fasti_ record a triumph of the consul Fabius over this last-named people, and another of his colleague Pœtelius over the men of Tibur and the Gauls--an ominous conjunction. But this new inroad of the barbarians, which threatened Rome with a second ruin, really proved a blessing; for the remaining Latin cities, which in the late conflicts had stood aloof, terrified by the presence of the Gauls, and seeing safety only in union, now renewed their league with Rome, and the Hernicans soon after followed their example. The glory of concluding this second league belongs to C. Plautius, the plebeian consul of the year 358 B.C. The Gauls now quitted Latium; and Privernum and Tibur, the only Latin cities which rejected the alliance, were both compelled to yield (357, 354 B.C.).
