High Quality Content by WIKIPEDIA articles! Euridice (also Erudice or Eurydice) is an opera by Jacopo Peri, with additional music by Giulio Caccini. (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 which recount the story of the legendary musician Orpheus and his wife Euridice.
