La Dafne (Daphne) is an early Italian opera, written in 1608 by the Italian composer Marco da Gagliano from a libretto by Ottavio Rinuccini. It is described as a favola in musica (fable set to music) composed in one act and a prologue. The opera is based on the myth of Daphne and Apollo as related by Ovid in the first book of the Metamorphoses. An earlier version of the libretto had been set to music in 1597–98 by Jacopo Peri, whose Dafne is generally considered to be the first opera.[1]
