In our "Nibelungenlied", however, it is no longer Attila, but Kriemhild, who is the central figure of the tragedy. Etzel, as he is called here, has sunk to the insignificant role of a stage king, a perfectly passive observer of the fight raging around him. This change was brought about perhaps by the introduction of Dietrich of Berne, the most imposing figure of all Germanic heroic lore. The necessity of providing him with a role corresponding to his importance, coupled with a growing repugnance on the part of the proud Franks to acknowledge defeat at the hands of the Huns, caused the person of Attila to dwindle in importance. Gradually, too, the role played by Kriemhild was totally changed. Instead of being the avenger of her brothers, as depicted in the Norse versions, she herself becomes the cause of their destruction. Etzel is not only innocent of any desire to harm the Nibelungs, but is even ignorant of the revenge planned by his wife. This change in her role was probably due to the feeling that it was incumbent upon her to avenge the murder of Siegfried. Our "Nibelungenlied" knows but little of the adventures of Siegfried's youth as depicted in the Norse versions. The theme of the poem is no longer the love of Sigurd, the homeless wanderer, for the majestic Valkyrie Brunhild, but the love idyll of Siegfried, the son of the king of the Netherlands, and the dainty Burgundian princess Kriemhild. The poem has forgotten Siegfried's connection with Brunhild; it knows nothing of his penetrating the wall of flames to awake and rescue her, nothing of the betrothal of the two. In our poem Siegfried is carefully reared at his father's court in the Netherlands, and sets out with great pomp for the court of the Burgundians. In the Norse version he naturally remains at Gunther's court after his marriage, but in our poem he returns to the Netherlands with his bride. This necessitates the introduction of several new scenes to depict his arrival home, the invitation to the feast at Worms, and the reception of the guests on the part of the Burgundians.
