 While Jacopo Peri's "Dafne" is generally recognised as the first work in the opera genre, and the earliest surviving opera is Peri's "Euridice", "L'Orfeo" is the earliest that is still regularly performed.
Euridice is an opera in a prologue and one act by the Italian composer Giulio Caccini.
 The libretto, by Ottavio Rinuccini, had already been set by Caccini's rival Jacopo Peri in 1600.
 Caccini's version of "Euridice" was first performed at the Pitti Palace, Florence on 5 December 1602.
 Caccini hurriedly prepared the score for the press and published it six weeks before Peri's version appeared.

Prosper-Didier Deshayes (mid 18th century – 1815) was an opera composer and dancer who lived and worked in France.
 In 1764 he was a balletmaster at the Comédie-Française.
 By 1774 he had become an assistant ("adjoint") at the Paris Opéra.
 His first opera "Le Faux serment ou La Matrone de Gonesse", a "comédie mêlée d'ariettes" in two acts, was first performed on 31 December 1785 at the Théâtre des Beaujolais in Paris and became a popular success.
 He went on to have another 18 works performed at various venues in Paris, but only two, "La faut serment" and "Zélie, ou Le mari à deux femmes", a 3-act "drame" first performed at the Salle Louvois on 29 October 1791, were ever published as musical scores.
 He also participated in the collaborative Revolutionary opera "Le congrès des rois", a 3-act "comédie mêlée d'ariettes", which combined music written by Deshayes and 11 other composers and was first performed by the Opéra-Comique at the Salle Favart on 26 February 1794.
 He died in Paris.

Euridice (also Erudice or Eurydice) is an opera by Jacopo Peri, with additional music by Giulio Caccini.
 It is the earliest surviving opera, Peri's earlier "Dafne" being lost.
 (Caccini wrote his own "Euridice" even as he supplied music to Peri's opera, published this version before Peri's was performed, in 1600, and got it staged two years later.)
 The libretto by Ottavio Rinuccini is based on books X and XI of Ovid's "Metamorphoses"
Orfeo ed Euridice (French version: Orphée et Eurydice ; English: "Orpheus and Eurydice") is an opera composed by Christoph Willibald Gluck based on the myth of Orpheus, set to a libretto by Ranieri de' Calzabigi.
 It belongs to the genre of the "azione teatrale", meaning an opera on a mythological subject with choruses and dancing.
 The piece was first performed at the Burgtheater in Vienna on 5 October 1762 in the presence of Empress Maria Theresa.
 "Orfeo ed Euridice" is the first of Gluck's "reform" operas, in which he attempted to replace the abstruse plots and overly complex music of "opera seria" with a "noble simplicity" in both the music and the drama.
