But when the will of Caesar was opened and it was found that he had given every Roman citizen a considerable gift, and when the multitude saw his body carried through the forum all disfigured with its wounds, they no longer kept themselves within the restraints of order and discipline, but after heaping round the body benches, railings, and tables from the forum, they set fire to them and burned it there; then, lifting blazing brands on high, they ran to the houses of the murderers with intent to burn them down, while others went every whither through the city seeking to seize the men themselves and tear them to pieces.
Not one of these came in their way, but all were well barricaded. There was a certain Cinna, however, one of the friends of Caesar, who chanced, as they say, to have seen during the previous night a strange vision. He dreamed, that is, that he was invited to supper by Caesar, and that when he excused himself, Caesar led him along by the hand, although he did not wish to go, but resisted. Now, when he heard that they were burning the body of Caesar in the forum, he rose up and went thither out of respect, although he had misgivings arising from his vision, and was at the same time in a fever.
At sight of him, one of the multitude told his name to another who asked him what it was, and he to another, and at once word ran through the whole throng that this man was one of the murderers of Caesar. For there was among the conspirators a man who bore this same name of Cinna, and assuming that this man was he, the crowd rushed upon him and tore him in pieces among them.1
This more than anything else made Brutus and Cassius afraid, and not many days afterwards they withdrew from the city. What they did and suffered before they died, has been told in the Life of Brutus.
