Hearing a knocking at a secret door and believing it to be the Queen, he opens it. To his surprise he finds that it is Clifford, who, imprisoned by Enrico but released by Leonora, has come to tell Rosmonda that she must leave England within the hour. It is Clifford's wish that Arturo escort her to Aquitania and marry her. The proposal surprises Arturo quite as much as it does Rosmonda. Though Rosmonda agrees to leave Enrico, she at first pleads against any alternative marriage; but then, urged by both Clifford and Arturo, she eventually capitulates and agrees to all her father’s wishes.
