The effect of the change was like enchantment. The delay of the Germans made it unnecessary to wait for them in Italy. Leaving Catulus, his colleague in the consulship, to check the Cimbri in Venetia, Marius went himself, taking Sylla with him, into the south of France. As the barbarian host came on, he occupied a fortified camp near Aix. He allowed the enormous procession to roll past him in their wagons toward the Alps. Then, following cautiously, he watched his opportunity to fall on them. The Teutons were brave, but they had no longer mere legionaries to fight with, but a powerful machine, and the entire mass of them, men, women, and children, in numbers which however uncertain were rather those of a nation than an army, were swept out of existence. The Teutons were destroyed on the 20th of July, 102. In the year following the same fate overtook their comrades. The Cimbri had forced the passes through the mountains. They had beaten the unscientific patrician Catulus, and had driven him back on the Po. But Marius came to his rescue. The Cimbri were cut to pieces near Mantua, in the summer of 101, and Italy was saved. The victories of Marius mark a new epoch in Roman history. The legions were no longer the levy of the citizens in arms, who were themselves the State for which they fought. The legionaries were citizens still. They had votes, and they used them; but they were professional soldiers with the modes of thought which belong to soldiers, and beside the power of the hustings was now the power of the sword. The constitution remained to appearance intact, and means were devised sufficient to encounter, it might be supposed, the new danger. Standing armies were prohibited in Italy. Victorious generals returning from campaigns abroad were required to disband their legions on entering the sacred soil. But the materials of these legions remained a distinct order from the rest of the population, capable of instant combination, and in combination irresistible save by opposing combinations of the same kind. The Senate might continue to debate, the Comitia might elect the annual magistrates. The established institutions preserved the form and something of the reality of power in a people governed so much by habit as the Romans. There is a long twilight between the time when a god is first suspected to be an idol and his final overthrow. But the aristocracy had made the first inroad on the constitution by interfering at the elections with their armed followers and killing their antagonists. The example once set could not fail to be repeated, and the rule of an organized force was becoming the only possible protection against the rule of mobs, patrician or plebeian.
