Il prigionier superbo

Il prigionier superbo (English: The Proud Prisoner) is an opera seria in three acts, composed by Giovanni Battista Pergolesi to a libretto attributed to Gennaro Antonio Federico, and based on an earlier libretto by Francesco Silvani for Gasparini's opera, La fede tradita e vendicata. It was premiered at the Teatro San Bartolomeo in Naples on 5 September 1733 and received further performances in October. The opera, with its labyrinthine plot involving the rivalry of Metalce (King of the Goths) and Viridate (Prince of Denmark) for the hand of Rosmene (a Norwegian princess whose father is Metalce's prisoner), soon sank into oblivion, but its comic intermezzo, La serva padrona (also by Pergolesi) was to achieve considerable success when performed on its own.
