Die Walküre
In accordance with this scheme Wagner preceded "Siegfried's Death" (later "Götterdämmerung" ("The Twilight of the Gods") with the story of Siegfried's youth, "Young Siegfried", later renamed "Siegfried". This was in turn preceded by "Die Walküre" ("The Valkyrie"), dealing with Siegfried's origins, the whole tetralogy being fronted by a prologue, "Das Rheingold". Because Wagner prepared his texts in reverse chronological sequence, "Die Walküre" was the third of the dramas to be conceived and written, but appears second in the tetralogy.
