Calphurnia is Caesar’s wife.
She is barren, which Caesar hopes will be cured during the race at Lupercal if Antony touches her as he passes by. She is disturbed by bad dreams the night before Caesar’s death, premonitory nightmares which cause her to cry out in fear in her sleep. Though she has never trusted in premonitions before, she attempts to keep Caesar from going to the Capitol, convinced that it would mean his death. She is partly successful, but Decius’s re-interpretation of her dream carries more force with Caesar, who leaves with his murderers.
