Are both Eine florentinische Tragödie and Alceste operas?
Alceste (Gluck) Alceste, Wq. 37 (the later French version is Wq. 44), is an opera by Christoph Willibald Gluck from 1767. The libretto (in Italian) was written by Ranieri de' Calzabigi and based on the play "Alcestis" by Euripides. The premiere took place on 26 December 1767 at the Burgtheater in Vienna.
L'italiana in Algeri L'Italiana in Algeri (] ; English: The Italian Girl in Algiers ) is an operatic "dramma giocoso" in two acts by Gioachino Rossini to an Italian libretto by Angelo Anelli, based on his earlier text set by Luigi Mosca. It premiered at the Teatro San Benedetto in Venice on 22 May 1813. The music is characteristic of Rossini's style, remarkable for its fusion of sustained, manic energy with elegant, pristine melodies.
