The couple visited Vienna and later Venice, where Rossini composed "Semiramide". Colbran created the title role, and even though the opera itself proved to be tremendously successful and was specifically designed to disguise her waning talents, she nonetheless disappointed the public. A visit to London in 1824 for a performance in the role commanded a high fee but received a poor critical response. After a disastrous appearance as Zelmira in 1824, she retired from the stage by the age of 42.
