As soon as Sulla had withdrawn to Asia, Cinna made no further concealment of his designs. Avowing himself the restorer of the late order of things, he demanded the recall of the exiles of his party, and the restoration of the laws of Sulpicius, that is to say, the full and final emancipation of Italy. In the actual temper of the public mind, such demands could not fail to produce a sedition in the Forum. Such, in fact, was the result. A disturbance ensued, and blood was shed. But Cinna had miscalculated his strength. The new citizens, upon whose efforts he relied, were few in number. The senate, his colleague Octavius, and even a majority of the tribunes of the plebs, together with the mass of the original citizens, united themselves against him. They flew to arms, and drove his partisans out of the city. Cinna, we may suppose, counted in this abortive attempt upon the support of Pompeius Strabo, while that general, reserved and perhaps undecided, contented himself with observing it from a distance, and leaving the two factions to weaken and exhaust each other.

The victorious party proceeded to deprive Cinna of the consulship, and elected L. Merula, a flamen of Jupiter, a man respectable for his birth and reputed integrity, in his room. Cinna, proscribed and outlawed, betook himself to the new citizens of Campania, and declaimed to them on the persecution to which he was exposed for his devotion to their interests. The Campanians discovered more zeal for the defence of their newly acquired rights than they had evinced in the struggle to obtain them. Cinna succeeded in collecting an armed following. Many exiles of his party flocked to his standard, and among them was Q. Sertorius, an officer of distinction. Nor did he scruple to unite himself with the Samnites and Lucanians, the avowed enemies of the republic. Clothed in black, with disordered hair and beard, he ventured to enter the camp of the Roman general commanding in Campania, and moved the soldiers to compassion at the sight of a consul kneeling to them in supplication. They insisted on placing themselves under his orders. At the head of a Roman army he demanded the restitution of his rights, and vowed the destruction of his opponents.

Wandering from coast to coast, and threading the ambuscades of a thousand enemies, Marius was not unapprised of the events that were passing. He found means of communicating with his friends, and when he suddenly threw himself on the coast of Etruria, he was joined by several adherents with a band of five hundred fugitive slaves. Etruria was crowded, as we have seen, with a population of serfs, whose native masters kept them in a state of degradation and misery. Unconscious of the political questions in agitation, these men flocked to the adventurer’s banner as the symbol of vengeance and plunder. While Marius advanced upon the city from the west, Cinna was slowly approaching in the opposite direction.

At the same time Sertorius and Carbo threatened her from other quarters, and Rome found herself encircled by four armies of her own rebellious citizens, backed by the resources of the Samnite insurrection. To resist these accumulating dangers, the senate hastily recalled Metellus, bidding him make peace with the Samnites on any terms. But the conditions they exacted in the insolence of this triumph—admission to the franchise, compensation for their losses, the surrender without return or reciprocity of their fugitive slaves—were intolerable to the pride of the Roman general. Metellus ventured to disobey his orders, and broke off the negotiation. He left a small detachment under his lieutenant Plautius to check the advance of the enemy, while he hastened in person to Rome. Plautius was speedily overpowered, and the rebel Romans were reinforced by the whole strength of the Samnite confederacy, which devoted Rome itself to destruction. There can be no peace, they exclaimed, for Italy until the forest shall be extirpated in which the Roman wolves have made themselves a den. The senate was reduced to extremity. Envoys were despatched to the quarters of Pompeius Strabo in Picenum; his command was acknowledged, his services were invoked, his return to the defence of the city earnestly entreated. At this moment Strabo might feel himself the arbiter of his country’s destinies; but he still vacillated as to his course, and continued apparently to treat with both parties, until the advancing successes of the Marians diminished the value of his adhesion.

Treason was at work within the city. For a moment Rome was opened to Marius, and he well-nigh succeeded in effecting his entrance by a gate on the side of the Janiculum, from which he was repulsed after a sharp engagement. Mutiny broke out in Strabo’s camp, which he had advanced almost to the walls. His soldiers seem to have personally detested him; a conspiracy was formed against his life, and defeated only by the devotion of his son, who threw himself on the ground and declared that the mutineers should pass over his body before they reached the object of their fury. The young Pompey was already beloved by the soldiers, and this spirited defiance saved the life of the father. But famine and pestilence quickly followed. The populace of the city were swept off in great numbers, nor were the soldiers, on either side, exempt from the contagion. The consuls, abandoning the unwholesome districts round the walls, withdrew their legions to the Alban mount. Strabo himself fell a victim to the disease, or, as some accounts relate, was killed by lightning. It is not improbable that he was actually assassinated.

This last blow paralysed the resistance of the senate. A first deputation was sent to Cinna, to arrange terms of accommodation. When these were refused, a second was only charged to solicit an amnesty. Cinna received it seated in his curule chair, with the ensigns of the consular office which he claimed to bear. Marius stood by his side, squalid and unshorn, and clothed in the black rags of an exile and an outlaw, and his gloomy silence interpreted, in the worst sense, the ambiguous reply which Cinna vouchsafed the deputation. But no further time was allowed for parley. The senate hastened to invite her conquerors within the walls.

Then, at last, Marius opened his mouth with bitter words: “An exile,” he exclaimed, “must not enter the city.” The restoration of Cinna to his consulship, of his associate to his dignities and privileges, may have saved Rome from being delivered to the Samnites for destruction; but the victorious generals had still their own soldiers to satisfy, and they did not shrink from surrendering the city to plunder and massacre. They had pledged their words for the safety of the consul Octavius, and the augurs whom he had consulted had ventured to assure him of his security. Fortified by these assurances he had repelled the entreaties of his friends to effect his escape, and had declared that as consul he would never desert his country. He had betaken himself with a small retinue to the Janiculum, and there seated himself in his curule chair, with the ensigns of his office around him. Here he soon learned that neither the dignity of his office nor the promises of the victors would command respect. But he refused to rise from his place, and when a band of assassins approached him, calmly offered himself to the sword.[90] His head was severed from his body, and carried to Cinna, by whose order it was suspended before the rostra. This, it is said, was the first instance of the public exhibition of these horrid trophies of civil war, and the custom, which became but too frequent in the subsequent contests of the Roman factions, was thus inaugurated in the person of the highest magistrate of the city. As the massacre proceeded, the bodies of the knights and meaner citizens were cast out for burial, but the mangled heads of the senators were reserved for exhibition in the Forum. The thirst for vengeance or plunder was succeeded by a savage delight in the horrors which accompanied it, and the populace itself, debauched and degraded, learned to gloat upon the blood of the victims. In the list of slain are included many of the noblest names of Rome. P. Crassus, who had been both consul and censor, either slew himself or was killed by the assassins. M. Antonius, celebrated at the time, and long afterwards remembered as one of the greatest of Roman orators, was murdered by the leader of a body of soldiers, whom he had almost moved by his eloquence to spare him. Two of the Julii, kinsmen of Julius Cæsar, the future dictator, suffered. Some were caught and murdered in the act of flying; others, who ventured to throw themselves upon the mercy of Marius, were coldly repulsed and cruelly slaughtered.

Marius himself seldom condescended to answer their entreaties; but his followers were instructed to spare those only to whom he held out his hand to kiss. The swords of the hired assassins were directed, in the first instance, against the adherents of Sulla and the aristocratic faction, the special objects of the conqueror’s vengeance; but their numbers were speedily swelled by slaves and Italians, who sacrificed men of every party to their indiscriminate fury.

For a few days Cinna and Marius allowed these ruffians to riot unchecked. At last they deemed it necessary to arrest their career of systematic murder and pillage. Sertorius was charged with the task of repressing them with a military force, and the assassins themselves were made to feel the edge of the sword they had so long wielded with impunity. But the new rulers of the city continued to destroy by the forms of judicial process the victims who had escaped tumultuary violence. Cinna could not pardon the illustrious Merula the crime of having succeeded to the consulship of which he had been himself deprived. The flamen of Jupiter opened his own veins, after a solemn declaration in writing that he had previously laid aside his tufted cap of office, that he might not involve his country in the guilt of sacrilege. Catulus, the noble colleague of Marius in the last battle against the Cimbri, threw himself on his knees, and vainly begged for life. “You must die,” was the only response vouchsafed him; and he was compelled to suffocate himself with charcoal in a newly plastered chamber.
