The Hildebrandslied relates how Hildebrand, after spending thirty years in Hungary, returns to North Italy, leaving behind him a wife and infant son Hadubrand. A false rumor of Hildebrand's death reaches Hungary when Hadubrand has achieved great renown as a warrior, so, when in quest for adventure the young man meets his father, he deems him an impostor and fights with him until the poem breaks off, leaving us uncertain whether father or son was victorious. But later poets, such as Kaspar von der Rhön, give the story a happy ending, thus avoiding the tragic note struck in Sorab and Rustem (p. 410). There existed so many of these ancient epic songs that Charlemagne undertook to collect them, but Louis I, his all too pious son, destroyed this collection on his accession to the throne, because, forsooth, these epics glorified the pagan gods his ancestors had worshipped! Still not all the Teutonic epics are of pagan origin, for in the second period we find such works as Visions of Judgment (Muspilli), Lives of Saints, and biblical narratives like Heliant (the Saviour), Judith, the Exodus, der Krist by Otfried, and monkish-political works like the Ludwigslied, or history of the invasion of the Normans. There is also the epic of Walter von Aquitanien, which, although written in Latin, shows many traces of German origin. In Walther von Aquitanien we have an epic of the Burgundian-Hunnish cycle written by Ekkehard of St. Gall before 973. It relates the escape of Walther von Aquitanien and his betrothed Hildegund from the court of Attila, where the young man was detained as a hostage. After describing their preparations for flight, their method of travel and camping, the poet relates how they were overtaken in the Vosges Mountains by a force led by Gunther and Hagen, who wish to secure the treasures they are carrying. Warned in time by Hildegund,--who keeps watch while he sleeps,--Walther dons his armor, and single-handed disposes of many foes. When Gunther Hagen, and Walther alone survive, although sorely disabled, peace is concluded, and the lovers resume their journey and reach Aquitania safely, where they reign happily thirty years. In the third period "the crusades revived the epic memories of Charlemagne and Roland and of the triumphs of Alexander," thus giving birth to a Rolandslied and an Alexanderlied, as well as to endless chivalrie epics, or romances in verse and prose.
