In a departure from traditional literary morality, it is the adulterous liaison of Poppea and Nerone which wins the day, although this triumph is demonstrated by history to have been transitory and hollow. In Busenello's version of the story all the major characters are morally compromised. Written when the genre of opera was only a few decades old, the music for "L'incoronazione di Poppea" has been praised for its originality, its melody, and for its reflection of the human attributes of its characters. The work helped to redefine the boundaries of theatrical music and established Monteverdi as the leading musical dramatist of his time.
