Plutarch, Cicero
Bernadotte Perrin, Ed.

48. But meantime his assassins came to the villa, Herennius a centurion, and Popillius a tribune, who had once been prosecuted for parricide and defended by Cicero; and they had helpers. After they had broken in the door, which they found closed, Cicero was not to be seen, and the inmates said they knew not where he was. [2] Then, we are told, a youth who had been liberally educated by Cicero, and who was a freedman of Cicero's brother Quintus, Philologus by name, told the tribune that the litter was being carried through the wooded and shady walks towards the sea. The tribune, accordingly, taking a few helpers with him, ran round towards the exit, but Herennius hastened on the run through the walks, and Cicero, perceiving him, ordered the servants to set the litter down where they were. [3] Then he himself, clasping his chin with his left hand, as was his wont, looked steadfastly at his slayers, his head all squalid and unkempt, and his face wasted with anxiety, so that most of those that stood by covered their faces while Herennius was slaying him. [4] For he stretched his neck forth from the litter and was slain, being then in his sixty-fourth year.¹ Herennius cut off his head, by Antony's command, and his hands—the hands with which he wrote the Philippics. For Cicero himself entitled his speeches against Antony ‘Philippics,’ and to this day the documents are called Philippics.
