"Aha," laughed Siegfried, "so that is what the fair lady has been up to, is it? Well, I think that for such waywardness we can try the same remedy that saved us from her power in Issland. Just call upon me the next time that trouble arises and we will subdue the proud Brunhild once for all." And so it chanced that with the help of the tarnkappe, Siegfried, all unseen, overcame the Queen in a mighty struggle that had been brought on by some show of authority on Gunther's part. At this time he wrested from her the magic ring and girdle that were the source of all her strength, and ever afterward there was peace in Gunther's household. It was not long before Siegfried with his bride returned to his home in Netherland, and was made king of that realm by his father Siegmund. No less brave and generous was he as a ruler than as a knight, and the years sped on in high prosperity for all the kingdom. But envy was at work, and all too soon was Siegfried's good fortune brought to an end. In the court of Burgundy Brunhild remained ill content. She could not understand why it was that if Siegfried was Gunther's subject, as he had declared himself to be when in Issland, he did not yield the obedience and service of a subject. As Gunther could not well explain Siegfried's deception and make known that the Netherlander was not indeed a vassal, he evaded Brunhild's questions. But the Queen was persistent, for it vexed her that Siegfried and his lady offered no homage at the court of Burgundy. At length one day she entreated the King: "Since you are unwilling to require a vassal's service of the King of Netherland, at least invite him to pay a visit to our court. Many years have passed since I have seen your sister Kriemhild, and I would be most glad to renew my friendship with her." Thus it came about that Siegfried and Kriemhild were bidden to visit Burgundy and in the course of a few months journeyed thither. The merriest of entertainment was provided, and Gunther and his queen were so lavish of their kindness that never would one have suspected Brunhild's deeply burning resentment. All at once, however, her ill feeling flamed into uncontrollable fury and brought about the sorrowful deed that ever afterward dimmed the fair honor of Burgundy. Shortly before the vesper service in the cathedral the two queens met one evening, and Kriemhild, having just witnessed some daring feats performed by Siegfried in the courtyard of the castle, exclaimed in admiration: "Oh, surely so bold a knight as my husband is fit to rule this land of Burgundy!" "But not while Gunther lives," returned Brunhild in wrath. "No vassal indeed can presume to fill the place and take upon him the dignity of his lord and master." "I am speaking not of a vassal, but of the King of Netherland," retorted Kriemhild. "Ah, but that same King, as I heard from his own lips when he bore Gunther company in Issland, is my husband's vassal!" exclaimed Brunhild flushing scarlet in her anger.
