Fulvius, when the people were gathered together in a full body, by the advice of Caius sent his youngest son into the market-place, with a herald's rod in his hand. He, being a very handsome youth, and modestly addressing himself, with tears in his eyes and a becoming bashfulness, offered proposals of agreement to the consul and the whole senate. The greatest part of the assembly were inclinable to accept of the proposals; but Opimius said, that it did not become them to send messengers and capitulate with the senate, but to surrender at discretion to the laws, like loyal citizens, and endeavour to merit their pardon by submission. He commanded the youth not to return, unless they would comply with these conditions. Caius, as it is reported, was very forward to go and clear himself before the senate; but none of his friends consenting to it, Fulvius sent his son a second time to intercede for them, as before. But Opimius, who was resolved that a battle should ensue, caused the youth to be apprehended and committed into custody; and then with a company of his foot-soldiers and some Cretan archers set upon the party under Fulvius. These archers did such execution, and inflicted so many wounds, that a rout and flight quickly ensued. Fulvius fled into an obscure bathing-house; but shortly after being discovered, he and his eldest son were slain together. Caius was not observed to use any violence against any one; but extremely disliking all these outrages, retired to Diana's temple. There he attempted to kill himself, but was hindered by his faithful friends, Pomponius and Licinius; they took his sword away from him, and were very urgent that he would endeavour to make his escape. It is reported that, falling upon his knee and lifting up his hands, he prayed the goddess that the Roman people, as a punishment for their ingratitude and treachery, might always remain in slavery. For as soon as a proclamation was made of a pardon, the greater part openly deserted him.
Caius, therefore, endeavoured now to make his escape, but was pursued so close by his enemies, as far as the wooden bridge, that from thence he narrowly escaped. There his two trusty friends begged of him to preserve his own person by flight, whilst they in the meantime would keep their post, and maintain the passage; neither could their enemies, until they were both slain, pass the bridge.
Caius had no other companion in his flight but one Philocrates, a servant of his. As he ran along, everybody encouraged him, and wished him success, as standers-by may do to those who are engaged in a race, but nobody either lent him any assistance, or would furnish him with a horse, though he asked for one; for his enemies had gained ground, and got very near him. However, he had still time enough to hide himself in a little grove, consecrated to the Furies.
In that place, his servant Philocrates having first slain him, presently afterwards killed himself also, and fell dead upon his master. Though some affirm it for a truth, that they were both taken alive by their enemies, and that Philocrates embraced his master so close, that they could not wound Caius until his servant was slain.
They say that when Caius's head was cut off, and carried away by one of his murderers, Septimuleius, Opimius's friend, met him, and forced it from him; because, before the battle began, they had made proclamation, that whoever should bring the head either of Caius or Fulvius, should, as a reward, receive its weight in gold.
Septimuleius, therefore, having fixed Caius's head upon the top of his spear, came and presented it to Opimius. They presently brought the scales, and it was found to weigh above seventeen pounds. But in this affair, Septimuleius gave as great signs of his knavery as he had done before of his cruelty; for having taken out the brains, he had filled the skull with lead. There were others who brought the head of Fulvius, too, but, being mean, inconsiderable persons, were turned away without the promised reward. The bodies of these two persons, as well as of the rest who were slain, to the number of three thousand men, were all thrown into the river; their goods were confiscated, and their widows forbidden to put themselves into mourning. They dealt even more severely with Licinia, Caius's wife, and deprived her even of her jointure; and as in addition still to all their inhumanity, they barbarously murdered Fulvius's youngest son;his only crime being, not that he took up arms against them, or that he was present in the battle, but merely that he had come with articles of agreement; for this he was first imprisoned, then slain.
But that which angered the common people most was, that at this time, in memory of his success, Opimius built the Temple of Concord, as if he gloried and triumphed in the slaughter of so many citizens.
