4. A Greek rhetorician, a friend of M. Brutus, who was present with him at the fatal battle of Philippi (B. C. 42), and having fled with him from the field, was induced to render him a last service by dispatching him with his own sword. He was subsequently reconciled with Octavian, who treated him with distinction, and to whom he rendered good service at the battle of Actium. (Plut. Brut. 52. 53.)
