Armida is an opera in three acts by Gioachino Rossini to an Italian libretto (dramma per musica) by Giovanni Schmidt, based on scenes from Gerusalemme liberata by Torquato Tasso.
Armida was written to be performed at the Teatro di San Carlo, Naples, on 11 November 1817 to celebrate the opening of the rebuilt opera house which had been destroyed by fire the previous year. Isabella Colbran sang the title role, which is one of the longest and most demanding that Rossini wrote, with difficult coloratura passages of every kind during the entire opera. The most notable are to be found in "D'amore al dolce impero" during Act 2, in the duets between Armida and Rinaldo, and in parts of the Act 3 finale.
The first modern staging took place at the Teatro Comunale Florence on 26 April 1952, during the Maggio Musicale Fiorentino, with Maria Callas and Francesco Albanese in the leading roles and Tullio Serafin conducting. More recently, performances were given in Aix-en-Provence in 1988, with June Anderson, Rockwell Blake, Raúl Giménez, under conductor Gianfranco Masini, and at the Rossini Opera Festival in 1993, with Renée Fleming and Gregory Kunde, under conductor Daniele Gatti.
