Lost operas by Claudio Monteverdi: The Italian composer Claudio Monteverdi (1567–1643), in addition to a large output of church music and madrigals, wrote prolifically for the stage.  His theatrical works were written between 1604 and 1643 and included ten operas, of which three—"L'Orfeo" (1607), "Il ritorno d'Ulisse in patria" (1640) and "L'incoronazione di Poppea" (1643)—have survived with their music and librettos intact.  In the case of the other seven operas, the music has disappeared almost entirely, although some of the librettos exist.  The loss of these works, written during a critical period of early opera history, has been much regretted by commentators and musicologists.
