 Yet Molière and Lully had quarrelled bitterly and the composer found a new and more pliable collaborator in Philippe Quinault, who would write the libretti for all but two of Lully's operas.On 27 April 1673, Lully's "Cadmus et Hermione" – often regarded as the first French opera in the full sense of the term – appeared in Paris.It was a work in a new genre, which its creators Lully and Quinault baptised "tragédie en musique", a form of opera specially adapted for French taste.
