La caverne

La caverne, ou Le repentir (French pronunciation: [la kavɛʁn u lə ʁəpɑ̃tiʁ], The Cavern, or Repentance) is an opera in three acts by French composer Jean-François Le Sueur.

The libretto, by Alphonse François "Paul" Palat-Dercy, is based on an episode from Lesage's novel Gil Blas.

La caverne was the first opera by Le Sueur to be staged and it became one of the most popular works of the French Revolutionary era.

Gil Blas is captured by a robber band led by Rolando, who hold him in their den (the cavern of the title) along with the noblewoman Séraphine.

In the finale, Gil Blas, who has managed to escape, brings a rescue party, who shoot the robbers and free the prisoners.
