Nibelunglied is the most commonly used name for a German epic poem written around 1200 A.D. The word Nibelung itself is used in various parts of the poem as the name of Siegfried's lands, people, and treasure, as well as an alternate name for the Burgundians, whose kingdom was overthrown by the Huns in 437 A.D. Some elements of great antiquity were woven into the text. The story of Brunhilde retains a separate existence in Old Norse literature. Tales of the heroic deeds of Siegfried also predate the epic, and the Fall of the Burgundians exists in an Eddaic poem. The poem was written in the classical period of medieval German literature, but does not share the "courtly" refinement of style characteristic of works from that period, perhaps due to the author's reinterpretation of ancient texts.[EB] This exquisite nineteenth century publication is extremely refined, however, and represents a high level of period book illustration and decoration.
