La muette de Portici

La muette de Portici (The mute girl of Portici) also known as Masaniello, is an opera in five acts by Daniel Auber, with a libretto by Eugène Scribe and Germain Delavigne.

It received its first performance at the Paris Opéra on 29th February 1828. Once extremely popular, it is now rarely performed.

According to tradition, it was the performance of this opera at the Théâtre de la Monnaie, Brussels on the 25 August 1830, which caused a riot that became the signal for the "Belgian Revolution" which led to Belgian independence.
