Just outside the city walls is another appalling sight: King Syphax is in chains taunted by the victorious King Massinissa, who is now dressed in Roman military regalia. The Cirtans have had enough and surrender. In the hall of the gigantic feline columns, Sophonisba grandiloquently surrenders and abases herself before her former fiancé and present husband's captor, Massinissa. He, in turn, demurs and, just as elaborately, pledges himself to her. In a ceremonial hall with indigenous deities, the pair further ritualize their solidarity. Sophonisba marries Massinissa, and it is resolved that she will not be subjected to being paraded in a Roman triumph.
