In Norse mythology, a valkyrie (from Old Norse: valkyrja, lit. 'chooser of the slain'), is one of a host of female figures who guide souls of the dead to the god Odin´s hall Valhalla. There, the deceased warriors become einherjar (Old Norse "single (or once) fighters"). When the einherjar are not preparing for the events of Ragnarök, the valkyries bear them mead. Valkyries also appear as lovers of heroes and other mortals, where they are sometimes described as the daughters of royalty, sometimes accompanied by ravens and sometimes connected to swans or horses.
Valkyries are attested in the Poetic Edda (a book of poems compiled in the 13th century from earlier traditional sources), the Prose Edda, the Heimskringla (both by Snorri Sturluson) and the Njáls saga (one of the Sagas of Icelanders), all written—or compiled—in the 13th century. They appear throughout the poetry of skalds, in a 14th-century charm, and in various runic inscriptions.
