Question: Are Dafne and The Rite of Spring both operas? 
Sentence (from "Dafne (Opitz-Schütz)"): Die Dafne (1627) to a libretto by Martin Opitz (which survives), and music by Heinrich Schütz (which is lost), 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.
