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.
Jacopo Corsi Jacopo Corsi (17 July 1561 – 29 December 1602) was an Italian composer of the late Renaissance and early Baroque and one of Florence's leading patrons of the arts, after only the Medicis. His best-known work is "Dafne" (1597/98), whose score he wrote in collaboration with Jacopo Peri. Six fragments of the score have survived, two by Corsi and four by Peri. The libretto, by Ottavio Rinuccini, has survived intact. Despite priority quibbles at the time, Dafne is generally accepted as the first opera.
