The stories of Wayland the Smith describe him as falling in love with Swanhilde, a Swan Maiden, who is the daughter of a marriage between a mortal woman and a fairy king, who forbids his wife to ask about his origins; on her asking him he vanishes. Swanhilde and her sisters are however able to fly as swans. But wounded by a spear, Swanhilde falls to earth and is rescued by the master-craftsman Wieland, and marries him, putting aside her wings and her magic ring of power. Wieland’s enemies, the Neidings, under Princess Bathilde, steal the ring, kidnap Swanhilde and destroy Wieland’s home. When Wieland searches for Swanhilde, they entrap and cripple him. However he fashions wings for himself and escapes with Swanhilde as the house of the Neidings is destroyed.
