Had the Cimbri chosen at this moment to recross the Alps into Italy, they had only to go and take possession, and Alaric would have been antedated by five centuries. In great danger it was the Senate's business to suspend the constitution. The constitution was set aside now, but it was set aside by the people themselves, not by the Senate. One man only could save the country, and that man was Marius. His consulship was over, and custom forbade his re-election. The Senate might have appointed him Dictator, but would not. The people, custom or no custom, chose him consul a second time--a significant acknowledgment that the Empire, which had been won by the sword, must be held by the sword, and that the sword itself must be held by the hand that was best fitted to use it. Marius first triumphed for his African victory, and, as an intimation to the Senate that the power for the moment was his and not theirs, he entered the Curia in his triumphal dress. He then prepared for the barbarians who, to the alarmed imagination of the city, were already knocking at its gates. Time was the important element in the matter. Had the Cimbri come at once after their victory at Orange, Italy had been theirs. But they did not come. With the unguided movements of some wild force of nature, they swerved away through Aquitaine to the Pyrenees. They swept across the mountains into Spain. Thence, turning north, they passed up the Atlantic coast and round to the Seine, the Gauls flying before them; thence on to the Rhine, where the vast body of the Teutons joined them, and fresh detachments of the Helvetii. It was as if some vast tide-wave had surged over the country and rolled through it, searching out the easiest passages. At length, in two divisions, the invaders moved definitely toward Italy, the Cimbri following their old tracks by the Eastern Alps toward Aquileia and the Adriatic, the Teutons passing down through Provence, and making for the road along the Mediterranean. Two years had been consumed in these wanderings, and Marius was by this time ready for them. The Senate had dropped the reins, and no longer governed or misgoverned; the popular party, represented by the army, was supreme. Marius was continued in office, and was a fourth time consul. He had completed his military reforms, and the army was now a professional service, with regular pay. Trained corps of engineers were attached to each legion. The campaigns of the Romans were thenceforward to be conducted with spade and pickaxe as much as with sword and javelin, and the soldiers learnt the use of tools as well as arms.
