What happens in Act III of Julius Caesar?
Act III opens at the Capitol on the Ides of March. Caesar arrives, brushing off Artemidorus's warning letter as self-serving. The conspirators gather under the guise of asking for Publius Cimber's return from exile. When Caesar refuses—declaring, "I am constant as the northern star"—Casca strikes first, and the senators follow suit, stabbing Caesar twenty-three times. His final words, directed at Brutus, are the famous "Et tu, Bruté?" Chaos ensues; Antony flees but quickly returns to negotiate with the conspirators, shaking each bloodied hand. Brutus allows him to speak at Caesar's funeral, despite Cassius's strong objection. Left alone with the body, Antony drops his diplomatic facade and predicts civil war. At the Forum, Brutus addresses the crowd with calm, logical arguments and wins them over. Antony follows with a poetic speech, using Caesar's will, the wounds as silent witnesses, and the ironic repetition of "Brutus is an honourable man" to completely shift the crowd's feelings. The plebeians riot, and a messenger arrives to announce that Octavius has entered Rome and that Brutus and Cassius have fled the city.
Analysis
Act III is the pivotal moment of the play, both structurally and rhetorically. Shakespeare presents two assassination scenes in quick succession—the actual killing and the symbolic one, where Antony's speech destroys Brutus's reputation—turning the act into a reflection on how language shapes and dismantles power.
The Capitol scene is crafted with meticulous precision: the conspirators' kneeling petition forms a striking image of false humility that Caesar misinterprets as flattery, his arrogance sealing his doom. Shakespeare uses the northern-star simile to illustrate Caesar's dangerous mix-up of steadfastness with rigidity; the very trait he values becomes his legacy.
After the assassination, the tonal shift marks one of Shakespeare's boldest moves. Antony's speech over the body transitions the play from a political thriller to an elegy, as his address to "Caesar's spirit" introduces the supernatural themes that will influence Acts IV and V.
The Forum speeches depict a clash between two rhetorical styles: Brutus's logical, balanced, and abstract Senecan prose versus Antony's everyday language that is associative, repetitive, and emotionally charged. Shakespeare allows Antony to prevail not because truth triumphs over falsehood, but because performance outshines argument. The crowd's fickleness—turning on a dime and then attacking Cinna the Poet for nothing more than his name—highlights mob rule as the true threat unleashed by Caesar's death. Irony serves as Antony's main weapon, with each repetition of "honourable man" gathering destructive power until the phrase ultimately collapses under its own sarcasm.
