Valkyrie
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.
