Cinna the poet On his way to attend Caesar's funeral, he is caught up in the riot caused by Antony's funeral oration. The mob at first confuses him with Cinna the conspirator, but even after they discover their error, they kill him anyway "for his bad verses."
Octavius Caesar The adopted son and heir of Julius Caesar; he is one of the triumvirs who rule following the death of Caesar. He and Antony lead the army that defeats Cassius and Brutus at Philippi.
M. Aemilius Lepidus He joins Antony and Octavius to form the Second Triumvirate to rule the Roman Empire following the assassination of Caesar. He is weak, and Antony uses him essentially to run errands.
Lucilius The officer who impersonates Brutus at the second battle of Philippi and is captured by Antony's soldiers. Antony admires his loyalty to Brutus and thus he protects him, hoping that Lucilius will choose to serve him as loyally as he did Brutus.
Pindarus At Philippi, he erroneously tells his master, Cassius, that the scout Titinius has been captured by the enemy when the scout has actually been greeted by the victorious forces of Brutus. Thinking that all is lost, Cassius decides to die; he has Pindarus kill him with the same sword that he used to help slay Caesar.
Titinius An officer in the army commanded by Cassius and Brutus, he guards the tent at Sardis during the argument between the two generals, and is a scout at Philippi for Cassius. After Cassius commits suicide when he mistakenly believes Titinius to have been taken prisoner by the enemy, Titinius kills himself in emulation of Cassius.
