In the "Prose Edda", written in the 13th century by Snorri Sturluson, valkyries are first mentioned in chapter 36 of the book "Gylfaginning", where the enthroned figure of High informs Gangleri (King Gylfi in disguise) of the activities of the valkyries and mentions a few goddesses. High says "there are still others whose duty it is to serve in Valhalla. They bring drink and see to the table and the ale cups." Following this, High gives a stanza from the poem "Grímnismál" that contains a list of valkyries. High says "these women are called valkyries, and they are sent by Odin to every battle, where they choose which men are to die and they determine who has victory". High adds that Gunnr ("war"), Róta, and Skuld—the last of the three he refers to as "the youngest norn"—"always ride to choose the slain and decide the outcome of battle". In chapter 49, High describes that when Odin and his wife Frigg arrived at the funeral of their slain son Baldr, with them came the valkyries and also Odin's ravens.
