The Marriage of Figaro (play)
The play formed the basis for an opera with a libretto by Lorenzo Da Ponte and music by Mozart, also called "The Marriage of Figaro" (1786). In 1799, another opera based on the same play, "La pazza giornata, ovvero Il matrimonio di Figaro", was produced in Venice with libretto by Gaetano Rossi and music by Marcos Portugal.
Gustav Mahler
Early in 1902 Mahler met Alfred Roller, an artist and designer associated with the Vienna Secession movement. A year later, Mahler appointed him chief stage designer to the Hofoper, where Roller's debut was a new production of "Tristan und Isolde". The collaboration between Mahler and Roller created more than 20 celebrated productions of, among other operas, Beethoven's "Fidelio", Gluck's "Iphigénie en Aulide" and Mozart's "Le nozze di Figaro". In the "Figaro" production, Mahler offended some purists by adding and composing a short recitative scene to Act III.
