'The Ring Cycle'. Fresco of the Nibelungenlied saga by Schnorr von Carolsfeld in the Royal residence, Munich. King Etzel and Rüdiger von Bechelaren. Attila or Etzel son of Osid, the king of Frisia was king of the Huns, in Hungary, where he ruled a large empire that included Austria and Germany. In the Nibelungenlied German epic, Etzel was portrayed as a noble and generous king, because the German poets see Etzel and the Huns as German people, not the barbarians from steppe of Central Asia.
