Padraic Colum,
The Children of Odin: The Book of Northern Myths
“ Iduna was troubled at what Loki, whom she deemed so wise, told her. Her eyes filled with tears that there might be more shining apples in the world than hers. "O Loki," she said, "it cannot be. No apples are more shining, and none smell so sweet, as the apples I pluck off the tree in my garden.""Go, then, and see," said Loki. "Just outside Asgard is the tree that has the apples I saw. Thou, Iduna, dost never leave thy garden, and so thou dost not know what grows in the world. Go outside of Asgard and see." ”
