Karlamagnús saga

The Karlamagnús saga, also called Karlamagnussaga or Karlamagnus-saga ("saga of Charlemagne") was a late-thirteenth-century Norse prose compilation and adaptation, made for Haakon V of Norway, of the Old French chansons de geste of the Matter of France dealing with Charlemagne and his paladins. In some cases, the Karlamagnús saga remains the only source for otherwise-lost Old French epics.
