Roland og Magnus kongen literally "Roland and King Magnus," also known under the English title "Roland at the Battle of Roncevaux" is a Norwegian ballad about the legendary hero Roland of Charlemagne's court. The ballad is cataloged NMB 171 (Ådel Blom ed., Norske mellomalderballadar), and categorized TSB type E 29. In the ballad, Roland's sword (known in Old French as Durendal) is compared to a sickle, its name corrupted to Dvælje=Dvolg (Dvelgedvolg, Dvergedolg, Dvelgedolgen), explained as meaning "dwarf-fiend" or "enemy of the dwarfs" Storm was of the opinion that the ballad could not be younger than the end of the 15th century, and Halvorsen also said it "must have been handed down orally since the late Middle Ages".
