alkyriur or Valkyries. The twelve nymphs of Valhalla. They were mounted on swift horses, and held drawn
swords in their hands. In the mêléc of battle they selected those destined to death, and conducted them to
Valhalla, where they waited upon them, and served them with mead and ale in cups of horn called skulls. The
chief were Mista, Sangrida, and Hilda. Valkyriur means “chooser of the slain.”
