The Rake's Progress and Stiffelio are both operas in how many acts?
The Rake's Progress The Rake's Progress is an opera in three acts and an epilogue by Igor Stravinsky. The libretto, written by W. H. Auden and Chester Kallman, is based loosely on the eight paintings and engravings "A Rake's Progress" (1733–1735) of William Hogarth, which Stravinsky had seen on 2 May 1947, in a Chicago exhibition.
Alessandro Severo Alessandro Severo (Alexander Severus, HWV A13) is an opera by George Frideric Handel composed in 1738. It is one of Handel's three pasticcio works, made up of the music and arias of his previous operas "Giustino", "Berenice" and "Arminio". Only the overture and recitatives (as well as the words) were new. The impresario Johann Jacob Heidegger probably selected the 1717 libretto by Apostolo Zeno, originally written for Antonio Lotti and re-used by many composers thereafter.
