 In the book Skáldskaparmál , Idunn is mentioned in its first chapter ( numbered as 55 ) as one of eight ásynjur ( goddesses ) sitting in their thrones at a banquet in Asgard for Ægir . In chapter 56 , Bragi tells Ægir about Iðunn 's abduction by the jötunn Þjazi . Bragi says that after hitting an eagle ( Þjazi in disguise ) with a pole , Loki finds himself stuck to the bird . Loki is pulled further and further into the sky , his feet banging against stones , gravel , and trees . Loki feels that his arms might be pulled out from his shoulders . Loki shouts and begs the eagle for a truce , and the eagle responds that Loki would not be free unless he made a solemn vow to have Iðunn come outside of Asgard with her apples . Loki accepts Þjazi 's conditions and returns to his friends Odin and Hœnir . At the time Þjazi and Loki agreed on , Loki lures Iðunn out of Asgard into " a certain forest " , telling her that he had discovered some apples that she would find worth keeping , and told Iðunn that she ought to bring her own apples with her so that she may compare them with the apples he has discovered . Þjazi arrives in eagle shape , snatches Iðunn , flies away with her and takes her to his home , Þrymheimr .
