CAPTURE OF ROME BY THE GAULS. =56.= The Gauls were now beginning their terrible incursions from the north into the valley of the Po, thus absorbing the attention of the Etruscans; and the time favored a fresh attack of the Romans upon Veii, the nearest state across the Tiber. The war began B. C. 405, and lasted ten years. The necessity of keeping an armed force continually in the field, gave rise to the standing army, which ultimately made so essential a part of Roman power; and, at the same time, obliged the patricians to study the interests of the people. It was now agreed that the soldiers should be regularly paid, and money secured for this purpose by a careful collection of the rents for public lands. The number of military tribunes was doubled. Their chief, the præfect of the city, was a patrician, and chosen by that order, but the remaining five were elected from either or both classes, by a free vote of the popular assembly. =57.= After ten years’ warfare with varying success, Veii was taken (B. C. 396) by the dictator Camillus. It is said that on the very day of its surrender, Melpum, the Etruscan stronghold in the north, fell before the Gauls. The loss of these two frontier fortresses began the rapid decline of Etrurian power. The joy of the Romans was commemorated by the whimsical custom, long continued, of concluding every festal game with a mock auction called the “Sale of Veientes.” Cape´na, Fale´rii, Nep´ete, and Sunium were likewise conquered, and with their lands became possessions of Rome. Within half a century, the Etruscans lost to the Gauls all their possessions in Campania and north of the Apennines, and to the Romans, all between the Cimin´ian forests and the Tiber. The nation had already lost its force through unbounded excess in luxury. The nobles were enormously rich, while the people were poor and enslaved. =58.= The war of the Romans against Volsin´ii was equally successful; but, by a sudden and terrible reverse, Rome was now doomed to suffer the fate which she too often inflicted. The Gauls, after conquering northern Etruria, overflowed the barrier of the Apennines and spread over central Italy. They met the entire Roman force near the little river Al´lia, and defeated it with great slaughter; then pushing on with irresistible power, they captured and burned the city. So overwhelming was the disaster, that the 16th of July, the date of the battle of the Allia, was pronounced a “black day” of ill-omen, on which no business could be safely transacted and no sacrifices acceptably offered.
