Sigurd (opera)
Sigurd is an opera in four acts and nine scenes by the French composer Ernest Reyer on a libretto by Camille du Locle and Alfred Blau. Like Wagner's Ring of the Nibelung, the story is based on the Nibelungenlied and the Eddas, with some crucial differences from the better known Wagnerian version (the role of the supernatural is limited and replaced in large part by fate; the initial version of the libretto with a prologue set in heaven was later cut out).
