Siegfried relates his adventure with the Rhine-daughters, and when Hagen asks him if it is true that he can understand the language of the birds, he tells the whole story of his life in the "Rheinfahrt," a song built up of all the motives which have been heard in the "Siegfried" division, the melody of the sword, the stir of the woods, the song of the mysterious bird, Mime's enticement, the love of Brünnhilde, and the flaming fire following each other in rapid and brilliant succession through the measures of the picturesque description.
