Las hadas
Although Gozzi's "La donna serpente" ("The Snake Woman") was the source for Wagner's plot, he took the names of "Die Feen"'s two principal characters, Ada and Arindal, from "Die Hochzeit". The libretto also introduced a fantastic theme that was not in the original play. The libretto displays themes and patterns that were to recur in Wagner's more mature works. These include redemption, a mysterious stranger demanding that their lover not ask their name, and long expository narratives.
