Note 506 — LIFE OF BRUTUS.
George Long translation
The father of this Brutus was of the faction of Marius, and tribunus plebis B.C. 83. After Sulla’s return he lost all power, and after Sulla’s death Pompeius (B.C. 77) marched against Brutus, who shut himself up in Mutina (Modena). A mutiny among his troops compelled him to open the gates, and Pompeius ordered him to be put to death, contrary to the promise which he had given (Life of Pompeius, c. 16).
The allusion at the beginning of this chapter is to the outbreak between Pompeius and Cæsar, B.C. 49.
