Il trovatore is an opera in four acts by Giuseppe Verdi to an Italian libretto largely written by Salvadore Cammarano, based on the Spanish play El trovador (1836) by Antonio García Gutiérrez. Set in the 15th century in Biscay and Aragon, Spain, it tells the story of a nobleman named Count di Luna, who falls in love with Leonora, a lady-in-waiting. However, Leonora in turn falls in love with Manrico, the titular troubadour of the opera. The premiere of Il trovatore took place at the Teatro Apollo in Rome in January 1853. This undated poster by Luigi Morgari depicts a scene from act 4 of the opera, in which Leonora encounters Manrico, who is imprisoned in di Luna's dungeon.Poster credit: Luigi Morgari; restored by Adam Cuerden
