 DATE: When some of the characters are attending the opera,  "Lincoronazione di Poppea" by Claudio Monteverdi is being  performed. It premiered in Venice in 1642, but by the time that the  story takes place (ca. 1807), it had been lost and all but  forgotten. A score wasnt rediscovered until 1888, and the first  modern performance was given in 1905. The anachronism is probably  intentional since Monteverdis tale of the destructiveness of erotic  desire foreshadows the events immediately after that scene.
