Lucius reminds the British court that Caesar’s successful invasion of Britain prompted Cymbeline’s uncle, who was then king, to promise an annual tribute in perpetuity to Rome. He speaks with respect for both the past king and Cymbeline, but asserts Caesar’s claim.

The Queen and Cloten argue against the tribute, Cloten more crudely. They cite Britain’s strength and independence, claiming that Caesar’s conquest was never total. Cymbeline confirms that he will not pay the tribute, citing a line of British kings and ancient laws that should be preeminent. He acknowledges that Caesar was a mentor to him when he was younger, but says that his refusal is honorable. Other states are also rising up. Lucius and Cymbeline establish that this will mean war, but agree to maintain their good personal relationship for the time being.

Pisanio is horrified by a letter he has received from Posthumus, which accuses Imogen of infidelity and instructs him to murder her.
