Wayland and the Valkyrs
The Valkyrs were supposed to take frequent flights to earth in swan plumage, which they would throw off when they came to a secluded stream, that they might indulge in a bath.

It is related that three of the Valkyrs, Olrun, Alvit, and Svanhvit, were once sporting in the waters, when suddenly the three brothers Egil, Slagfinn, and Völund, or Wayland the smith, came upon them, and securing their swan plumage, the young men forced them to remain upon earth and become their wives. The Valkyrs, thus detained, remained with their husbands nine years, but at the end of that time, recovering their plumage, or the spell being broken in some other way, they effected their escape.
