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"
Katolophyromai Katolophyromai is the headword in a musical fragment from the first stasimon of "Orestes" by Euripides (lines 338-344, Vienna Papyrus G 2315). It means "I cry, lament so much." In 1892, among a number of papyri from Hermopolis, Egypt, in the collection of Archduke Rainer Ferdinand of Austria, a fragment was discovered and published by the papyrologist Karl Wessely, containing a mutilated passage with musical notation. Although Vienna Papyrus G 2315 dates to the third century B.C., the melody recorded on it may have been written much earlier.
