Portia is the daughter of Cato and the wife of Brutus. She is proud of both of these, and is the definition of a stoic Roman woman.
Highly intelligent, she cannot be fobbed off by Brutus’s excuses, as she knows him too well. She insists on sharing all that she can of his life. She is worried about him and his intentions, and when Brutus leaves for the Capitol intent on killing Caesar, she is a nervous wreck. When civil war breaks out and she realizes the strength of Brutus’s enemy, she commits suicide.
