Iðunn (possibly meaning "ever young"), often anglicized as Idun or Idunn, is a goddess in Norse mythology. Iðunn only appears in the Poetic Edda, compiled in the 13th century from earlier traditional sources, and the Prose Edda, written in the 13th century by Snorri Sturluson. In both sources, she is described as the wife of the skaldic god Bragi, and in the Prose Edda, also as a keeper of apples that grant the gods eternal youthfulness. Idunn Mons, a mons of the planet Venus, is named after Iðunn. In myth, she was abducted from Asgard by Thiazi , a giant, who made a deal with Loki (who was spying on Thiazi and got caught, and used Idunn's apples as a bargaining tool). She was eventually returned to Asgard by Loki himself.
