What genre are both Euridice and Der Kaiser von Atlantis?
Euridice (Peri) 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"
Die Kluge Die Kluge. Die Geschichte von dem König und der klugen Frau ("The Wise [Girl]. The Story of the King and the Wise Woman") is an opera in 12 scenes written by Carl Orff. It premiered in Frankfurt, Germany, on 20 February 1943. Orff referred to this opera as a "Märchenoper " (fairy tale opera). The composer also wrote the libretto, based on "Die Kluge Bauerntochter" ("The Peasant's Wise Daughter") from the Grimm's Fairy Tales. A performance lasts for about 90 minutes and is often paired with Orff's "Der Mond".
