Dafne

Die Dafne (1627) is an opera. Its libretto was written by Martin Opitz (which survives) and its music was composed by Heinrich Schütz (which is lost). It has traditionally been regarded as the first German opera, though it has also been proposed more recently that it was in fact a spoken drama with inserted song and ballet numbers.
