The Life and Death of Julius Caesar — Act 2, Scene 1: Rome. BRUTUS's orchard.

In Brutus’s orchard before dawn, Brutus wakes his servant Lucius and thinks over Cassius’s pressure against Caesar. He decides Caesar must be killed for Rome’s good, not from any personal grievance, and he convinces himself that power will corrupt Caesar if he is crowned. Lucius brings him an anonymous letter urging him to awake and act for Rome, which Brutus takes as further proof. Cassius arrives with the other conspirators, and Brutus joins their plan but refuses to swear an oath. The men discuss who should be involved, and Brutus excludes Cicero while Cassius argues to include Antony. Portia then confronts Brutus about his secret worries, and Caius Ligarius arrives to join Brutus after being inspired by his cause.
