Der Ring des Nibelungen
At Bayreuth, he assisted in making the first fair copy of "Der Ring des Nibelungen". Wagner treated him as one of the "chosen few", and it was natural that he should take a part in the first Bayreuth Festival in 1876. Wagner then sent him to Vienna to stage "Siegfried" and "Götterdämmerung" there, the last two of his operatic tetralogy, "Der Ring des Nibelungen".
