Plutarch: Cicero's death
ut in the meantime the assassins were come with a band of soldiers, Herennius, a centurion, and Popillius, a tribune, whom Cicero had formerly defended when prosecuted for the murder of his father. Finding the doors shut, they broke them open, and Cicero not appearing, and those within saying they knew not where he was, it is stated that a youth, who had been educated by Cicero in the liberal arts and sciences, an emancipated slave of his brother Quintus, Philologus by name, informed the tribune that the litter was on its way to the sea through the close and shady walks. The tribune, taking a few with him, ran to the place where he was to come out. And Cicero, perceiving Herennius running in the walks, commanded his servants to set down the litter; and stroking his chin, as he used to do, with his left hand, he looked steadfastly upon his murderers, his person covered with dust, his beard and hair untrimmed, and his face worn with his troubles. So that the greatest part of those that stood by covered their faces whilst Herennius slew him. And thus was he murdered, stretching forth his neck out of the litter, being now in his sixty-fourth year. Herennius cut off his head, and, by Antony's command, his hands also, by which his Philippics were written; for so Cicero styled those orations he wrote against Antony, and so they are called to this day.
