"Ah," the Gibichung cried, joyfully; "our oath of brotherhood upon that! Gutrune shall be thine, thou ours, Brünnhilde mine."

Thus it was agreed. Hagen filled a drinking horn, while the two men cut their arms and let their blood mingle in the cup. Having drunk, they swore fidelity in the drink, and Hagen cut the horn in two with a single blow, while Siegfried and Gunther joined hands.

Putting on his armour again, Siegfried declared they should at once go forth and win Brünnhilde for Gunther.

"Wilt thou not rest, first?"

So eager was the enchanted Siegfried to win for another his own bride that he would take no rest till it was done; so Hagen was left to guard the hall till their return. Soon Gunther and the knight were pushing off from the river bank, and floating down the middle of the stream.

Hagen, the half Gibichung, half Nibelung, thought of nothing but winning the Rheingold for the Nibelungs. He had sent Gunther after another's bride, by means of an evil enchantment, and when she was brought to the hall, she would certainly be wearing the ring. Thus the prize of the Nibelungen would once more be within the grasp of an evil race, and that which might be a power for good if rightly used, would become a power for evil and be badly abused.

Scene III

While Siegfried and Gunther were on their way to fetch Brünnhilde, she sat lonely upon her rock, looking at the ring given her by Siegfried. As long as she looked upon it, she felt Siegfried to be near; nevertheless she was lonely. Very soon she heard the thunder.

"It is Donner! It is like a greeting to me from the Eternals," she thought, smiling half sadly. Once again she heard it and saw the flash of lightning. In the clouds, she saw Waltraute, her sister, coming on her winged horse, and Brünnhilde started up joyfully.

"Wotan has forgiven me," she cried, running to meet Waltraute, who arrived in great excitement.
