Plutarch, Cato the Younger
Bernadotte Perrin, Ed.

28. And now the clerk produced the law, but Cato would not suffer him to read it; and when Metellus took it and began to read it, Cato snatched the document away from him. Then Metellus, who knew the law by heart, began to recite it, but Thermus clapped a hand upon his mouth and shut off his speech. [2] At last, seeing that the men were making a struggle which he could not resist, and that the people were giving way and turning towards the better course, Metellus ordered men-at-arms, who were standing at a distance, to come running up with terrifying shouts. This was done, and all the people dispersed, leaving Cato standing his ground alone and pelted with sticks and stones from above. Here Murena, who had been denounced and brought to trial by him,¹ [3] came to his relief, and holding his toga before him, crying to those who were pelting him to stop, and finally persuading Cato himself and folding him in his arms, he led him away into the temple of Castor and Pollux.

When, however, Metellus saw the space about the tribunal² empty and his opponents in flight through the forum, being altogether persuaded that he had won the day, he ordered his armed men to go away again, and coming forward himself in orderly fashion attempted to have the law enacted. [4] But his opponents, quickly recovering from their rout, advanced again upon him with loud and confident shouts, so that his partisans were overwhelmed with confusion and terror. They supposed that their enemies had provided themselves with arms from some place or other in order to assail them, and not a man stood his ground, but all fled away from the tribunal. [5] So, then, when these had dispersed, and when Cato had come forward with commendation and encouragement for the people, the majority of them stood prepared to put down Metellus by any and every means, and the senate in full session announced anew that it would assist Cato and fight to the end against the law, convinced that it would introduce sedition and civil war into Rome.
