Brunhilde (Brynhildr, Brunhilda, Brunhilde, Brünhild) was a female warrior, one of the Valkyries, and in some versions the daughter of the principal god Odin. She defies Odin and is punished by imprisonment within a ring of fire until a brave hero falls in love and rescues her. Siegfied (Sigurðr, Sigurd) brakes the spell, falls in love with her and gives her the ring, Andvarinaut. Siegfied is tricked and accused of infidelity. Eventually Brunhilde kills herself when she learns that Sigurd had betrayed her with another woman (Gudrun), not knowing he had been bewitched into doing so by Grimhild.
