Nibelungen Lied (i.e. Lay of the Nibelungen), an old German epic, of date, it is presumed, earlier than the 12th century; it consists of two parts, the first ending with the murder of Siegfried by Hagen, his wresting of the hoard (see supra) from his widow, Kriemhild, and burying it at the bottom of the Rhine, and the second relating the vengeance of Kriemhild and the annihilation of the whole Burgundian race, Kriemhild included, to whom the treasure had originally belonged; to the latter part the name of the Nibelungen Not (or Distress) has been given.
