Two tribunes, Flavius and Murellus, find scores of Roman citizens wandering the streets, neglecting their work in order to watch Julius Caesar’s triumphal parade; Caesar has defeated the sons of the Roman general Pompey, in battle.
Caesar enters with his entourage, including the military and political figures Brutus, Cassius, and Antony. A Soothsayer calls out to Caesar to “beware the Ides of March,” but Caesar ignores him and proceeds with his victory celebration.
