The Rhinemaidens are the three water-nymphs ("Rheintöchter" or "Rhine daughters") who appear in Richard Wagner's opera cycle "Der Ring des Nibelungen".
 Their individual names are Woglinde, Wellgunde and Flosshilde (Floßhilde), although they are generally treated as a single entity and they act together accordingly.
 Of the 34 characters in the "Ring" cycle, they are the only ones who did not originate in the Old Norse "Eddas".
 Wagner created his Rhinemaidens from other legends and myths, most notably the "Nibelungenlied" which contains stories involving water-sprites (nixies) or mermaids.
 The key concepts associated with the Rhinemaidens in the "Ring" operas—their flawed guardianship of the Rhine gold, and the condition (the renunciation of love) through which the gold could be stolen from them and then transformed into a means of obtaining world power—are wholly Wagner's own invention, and are the elements that initiate and propel the entire drama.
Siegfried, WWV 86C, is the third of the four music dramas that constitute "Der Ring des Nibelungen" ("The Ring of the Nibelung"), by Richard Wagner.
 It premiered at the Bayreuth Festspielhaus on 16 August 1876, as part of the first complete performance of "The Ring" cycle.
This is a discography of "Götterdämmerung", the fourth of the four operas that make up "Der Ring des Nibelungen" ("The Ring of the Nibelung"), by Richard Wagner, which received its premiere at the Bayreuth Festspielhaus on 17 August 1876.
The Jahrhundertring ("Centenary Ring") was the production of Richard Wagner's "Ring Cycle", "Der Ring des Nibelungen", at the Bayreuth Festival in 1976, celebrating the centenary of both the festival and the first performance of the complete cycle.
 The festival was directed by Wolfgang Wagner and the production was created by the French team of conductor Pierre Boulez, stage director Patrice Chéreau, stage designer Richard Peduzzi, costume designer Jacques Schmidt and lighting designer André Diot.
 The cycle was shown first in 1976, then in the following years until 1980.
 It was filmed for television in 1979 and 1980.
 While the first performance caused "a near-riot" for its brash modernity, the staging, termed the beginning of "Regietheater" (director's theater), established a standard for later productions.
Wilhelm Richard Wagner ( ; ] ; 22 May 181313 February 1883) was a German composer, theatre director, polemicist, and conductor who is primarily known for his operas (or, as some of his later works were later known, "music dramas").
 Unlike most opera composers, Wagner wrote both the libretto and the music for each of his stage works.
 Initially establishing his reputation as a composer of works in the romantic vein of Weber and Meyerbeer, Wagner revolutionised opera through his concept of the "Gesamtkunstwerk" ("total work of art"), by which he sought to synthesise the poetic, visual, musical and dramatic arts, with music subsidiary to drama.
 He described this vision in a series of essays published between 1849 and 1852.
 Wagner realised these ideas most fully in the first half of the four-opera cycle "Der Ring des Nibelungen" ("The Ring of the Nibelung").
The Love for Three Oranges, Op. 33, also known by its French language title L'amour des trois oranges (Russian: Любовь к трём апельсинам , "Lyubov' k tryom apel'sinam"), is a satirical opera by Sergei Prokofiev.
 Its French libretto was based on the Italian play "L'amore delle tre melarance" by Carlo Gozzi.
 The opera premiered at the Auditorium Theatre in Chicago, Illinois, on 30 December 1921.
Das Rheingold ( ; The Rhinegold), WWV 86A, is the first of the four music dramas that constitute Richard Wagner's "Der Ring des Nibelungen," or in English, 'The Ring of the Nibelung'.
Der Ring des Nibelungen (The Ring of the Nibelung), WWV 86, is a cycle of four German-language epic music dramas composed by Richard Wagner.
 The works are based loosely on characters from the Norse sagas and the "Nibelungenlied".
 The composer termed the cycle a "Bühnenfestspiel" (stage festival play), structured in three days preceded by a " " ("preliminary evening").
 It is often referred to as the Ring Cycle, "Wagner's Ring", or simply "The Ring".
The evolution of Richard Wagner's operatic tetralogy "Der Ring des Nibelungen" ("The Ring of the Nibelung") was a long and tortuous process, and the precise sequence of events which led the composer to embark upon such a vast undertaking is still unclear.
 The composition of the text took place between 1848 and 1853, when all four libretti were privately printed; but the closing scene of the final opera, "Götterdämmerung", was revised a number of times between 1856 and 1872.
 The names of the last two Ring operas, "Siegfried" and "Götterdämmerung", were probably not definitively settled until 1856.
Götterdämmerung ( ; Twilight of the Gods), WWV 86D, is the last in Richard Wagner's cycle of four music dramas titled "Der Ring des Nibelungen " ("The Ring of the Nibelung", or "The Ring" for short).
 It received its premiere at the Bayreuth Festspielhaus on 17 August 1876, as part of the first complete performance of the "Ring".
