War being declared against Mithridates, king of Pontus, was the signal of discord between Marius and Sylla. These two rivals, whose animosity knew no bounds, demanded at the same time the command of the army. Sylla obtained it from the Senate, and immediately went to place himself at the head of his troops. Marius took advantage of his absence, and, with the assistance of the tribune Sulpicius, he so excited the people against the nobles, that Sylla was deprived of his command which was conferred upon him. Sylla, far from obeying the sentence of the people, marched straight to Rome with his army, consisting of forty thousand men. This was the first time, since Coriolanus, that this great city had been besieged by one of its own citizens. Destitute of everything, its only defence being a few soldiers got together in haste by Marius, it did not make a long resistance. Sylla entered as an enemy; the multitude mounted upon the roofs of the houses, armed with anything they could lay hold of, and poured such a shower of stones and tiles upon the heads of his soldiers, that they could not advance. Sylla, forgetful of what he owed to his country and to himself, cried out to his men to set fire to the houses; and, arming himself with a blazing brand, gave them the example. Marius, too weak to contend with his rival, abandoned to him the centre of the empire. The conqueror affected great moderation, prevented the pillage of his country, reformed the government, raised the authority of the Senate upon the ruins of that of the people, put to death Sulpicius, with ten other senators, partisans of his rival, and embarked for Asia. This second absence replunged Rome into fresh misfortunes; the faction of the people, of which Marius was the soul, excited by Cinna, took courage again. This consul, having won over some tribunes, caused so much trouble, that he was driven from the city and deprived of the consulate; but he succeeded in gaining to his quarrel a large army encamped in the Campania, and almost all the peoples of Italy. Marius, who had taken refuge in Africa, recrossed the sea, and came to join Cinna; he was immediately declared pro-consul. It was proposed to give him fasces and lictors, but he rejected them: “Such honours,” said he, “would not become a banished man.” His party held a council, and it was determined to go and attack Rome: Sylla had set them the example.
