Die Nibelungenklage or Die Klage (English: the lament; Middle High German: Diu Klage) is an anonymous Middle High German heroic poem. The poem describes the laments for and burial of the dead from the Nibelungenlied, as well as the spread of the news of the catastrophe that ended the other poem, and the fates of the various characters who survived. It was likely written at around the same time as the Nibelungenlied (c. 1200), and is appended to it as though it were another episode (âventiure).
