Brunhild, also known as Brunhilda or Brynhild (Old Norse: Brynhildr [ˈbrynˌhildz̠], Middle High German: Brünhilt, Modern German: Brünhild or Brünhilde), is a female character from Germanic heroic legend. She may have her origins in the Visigothic princess and queen Brunhilda of Austrasia. In the Norse tradition, Brunhild is a shieldmaiden or valkyrie, who appears as a main character in the Völsunga saga and some Eddic poems treating the same events. In the continental Germanic tradition, where she is a central character in the Nibelungenlied, she is a powerful Amazon-like queen.
