The Third Citizen represents the collective voice of Rome’s common people—malleable, emotional, and vulnerable to eloquence. Present in the Forum scene (Act 3, Scene 2) when Brutus addresses the crowd after Caesar’s assassination, the Third Citizen initially accepts the assassins’ justifications with simple faith. When Brutus claims he killed Caesar only to preserve Rome’s liberty, the Third Citizen declares, “Let him go up into the public chair; We’ll hear him.” Yet moments later, when Antony takes the same stage and speaks with calculated passion about Caesar’s wounds and his will, the Third Citizen’s loyalty inverts entirely. He shifts from “Caesar’s better parts / Shall be crown’d in Brutus” to demanding revenge and threats of arson against the conspirators’ homes.
This character’s volatility illuminates the play’s central tragedy: the gap between reason and emotion, between public rhetoric and actual power. The Third Citizen does not reason carefully—he feels, and his feelings are redirected by whoever speaks last and most movingly. Antony’s repetition of “Brutus is an honourable man” becomes so ironic that the crowd cannot help but hear its inversion. The Third Citizen experiences this shift not as manipulation but as awakening. He believes himself capable of judgment, yet his judgment proves as unstable as wind.
In Act 3, Scene 3, the Third Citizen reappears in the mob that hunts down Cinna the poet. Here, the full danger of the crowd’s power becomes visible. When Cinna claims his name is Cinna, the Third Citizen—alongside his fellows—does not distinguish between the poet and the conspirator. “Tear him for his bad verses,” one shouts. The Third Citizen participates in this scapegoating, transforming personal grief over Caesar into collective violence against a stranger. Shakespeare uses this moment to show that oratory’s power, while terrifying, extends only so far: once unleashed, the mob’s hunger for blood and revenge transcends any single voice’s control. The Third Citizen becomes, in effect, the play’s warning about democracy’s capacity to become tyranny through collective passion rather than individual will.
