2. P.ServiliusCasca, one of the conspirators against Caesar, who aimed the first stroke at his assassination, B. C. 44. He was in that year tribune of the plebs, and soon afterwards fled from Rome, as he anticipated the revenge which Octavianus was going to take. His leaving Rome as tribune was against the constitution, and his colleague, P. Titius, accordingly carried a decree in the assembly of the people, by which he was deprived of his tribuneship. He fought in the battle of Philippi, and died shortly afterwards. (Appian App. BC 2.113, 115, 117; D. C. 44.52, 46.49 ; Cic. Philipp. 13.15, ad Att. 1.17, ad Brut. 1.18 ; Plut. Brut. 17, 45.)
