Opera in three acts, a prologue and an epilogue, by Jacques Offenbach (1819-1880), with a libretto in French by Jules Barbier (1825-1901), based on a work that Barbier himself and Michel Carré (1821-1872) had written based on stories by E.T.A. Hoffmann (1776-1822). Approximate duration: 2 h 45 min Recommended for those over 15 years old. The young poet Hoffmann, accompanied by Nicklausse, his alter ego and confidant, is in a tavern next to the theatre where Mozart's Don Giovanni is being performed. During the opera's intermission, some diners arrive at the bar who, upon seeing the poet, encourage him to sing and tell them the story of his famous love affairs. Hoffmann finally gives in and shares with them the stories of Olympia, Antonia and Giulietta. They, absorbed in the poet's stories, remain in the tavern, forgetting about the opera performance..
