German traits obvious in the _Hildebrandslied_, and strong through the Latin of the _Waltarius_, evince themselves in the epic of the _Nibelungenlied_ and in the _Kudrun_, often called its companion piece. The former holds the strength of German manhood and the power of German hate, with the edged energy of speech accompanying it. In the latter, German womanhood is at its best. Both poems, in their extant form, belong to the middle or latter part of the twelfth century, and are not unaffected by influences which were not native German.
The _Nibelungenlied_ is but dimly reminiscent of any bygone love between Siegfried and Brunhilde, and carries within its own narrative a sufficient explanation of Brunhilde's jealous anger and Siegfried's death. Kriemhild is left to nurse the wrath which shall never cease to devise vengeance for her husband's murderers. Years afterwards, Hagen warns Gunther, about to accept Etzel's invitation, that Kriemhild is _lancraeche_ (long vengeful). The course of that vengeance is told with power; for the constructive soul of a race contributed to this Volksepos. The actors in the tragedy are strikingly drawn and contrasted, and are lifted in true epic fashion above the common stature by intensity of feeling and the power of will to realize through unswerving action the prompting of their natures. The fatefulness of the tale is true to tragic reality, in which the far results of an ill deed involve the innocent with the guilty.
A comparison of the poem with the _Hildebrandslied_ shows that the sense of the pathetic had deepened in the intervening centuries. There is scarcely any pathos in the earlier composition, although its subject is the fatal combat between father and son. But the _Nibelungen_, with a fiercer hate, can set forth the heroic pathos of the lot of one, who, struggling between fealties, is driven on to dishonour and to death. This is the pathos of the death of Rüdiger, who had received the Burgundians in his castle on their way to Etzel's Court, had exchanged gifts with them, and betrothed his daughter to the youngest of the three kings. He was as unsuspecting as Etzel of Kriemhild's plot. But in the end Kriemhild forces him, on his fealty as liegeman, to outrage his heart and honour, and attack those whom he had sheltered and guided onward--to their death.
