Idun keeps the golden apples of youth in Asgard, and on those apples the immortality of the gods depends. She is among the quieter figures of the Norse pantheon, but the one myth that places her at the center of events makes clear that without her, the divine order itself would crumble.
Who is Idun?
Idun is the goddess entrusted with the apples that preserve the youth and vigor of the Aesir. Whenever the gods feel age beginning to press upon them, they come to Idun and she gives them an apple from her store, and youth returns. The Prose Edda of Snorri Sturluson presents this function as absolutely essential to the divine order: the gods are not intrinsically immortal but sustained by Idun's care. She is described as wise and gentle, and her husband is Bragi, the god of poetry. Together they represent two of the more peaceful and civilizing forces within Asgard.
Origins and the name
Idun's name appears in Old Norse as Iðunn. The etymology is disputed. One reading connects it to the Old Norse verb iðja, meaning to do again or to renew, which fits her role as the restorer of youth with striking precision. Another interpretation links the name to a root meaning the ever-young one or the rejuvenating one. She is attested primarily in the Prose Edda and in the skaldic poem by Thjodolf of Hvin called Haustlong, which gives the fullest surviving account of her abduction. The Poetic Edda's Lokasenna also names her, in passing, as the wife of Bragi.
Myths and stories
The central myth of Idun is her abduction by the giant Thjazi. The story begins with Loki, who is captured by Thjazi while traveling and forced to promise that he will lure Idun out of Asgard. Loki keeps his promise: he tricks Idun into leaving the safety of the divine realm by telling her he has found apples even finer than hers beyond Asgard's walls, and persuades her to bring her own apples for comparison. The moment she steps outside, Thjazi swoops down in the form of an eagle and carries her off to his hall in Thrymheim.
The consequences are immediate. Without Idun's apples the gods begin to age. Their hair turns grey, their joints stiffen, and the strength drains from their limbs. The Aesir soon realize that Loki is to blame. They threaten him with death unless he restores Idun, and he agrees. Borrowing Freya's cloak of falcon feathers, Loki flies to Thrymheim and finds Idun alone while Thjazi is out at sea. He transforms her into a nut, takes her in his talons, and races back toward Asgard. Thjazi returns, sees that Idun is gone, and gives chase in eagle form. The Aesir, watching from Asgard's walls, build a great pyre of wood shavings. Loki crosses the wall with Idun and the gods light the pyre; Thjazi, unable to stop, flies through the flames and is burned to death. Youth returns to the gods the moment Idun is safely back in Asgard.
Symbols and attributes
Idun is inseparable from her basket or box of golden apples. The apples are not a single finite supply but a perpetually renewed store that exists as long as Idun tends them. No rune or weapon is associated with her; her power is the quiet, steady power of renewal rather than force. Some later Scandinavian imagery connects her to spring and to the renewal of the natural world, a reflection of what her apples do for the gods.
Family and relationships
Idun is the wife of Bragi, who is the god of poetry and eloquence and is sometimes said to be a son of Odin. Their pairing links youth and renewal with the art of verse. Idun has no children named in the sources. Her most significant relationship beyond her marriage is her exposure to Loki's schemes: it is his actions, both in causing her abduction and then in rescuing her, that define her one major myth.
Worship and legacy
No dedicated cult sites for Idun are recorded in historical sources, but her function as a keeper of divine life would have made her relevant to prayers for health and longevity. In modern Heathenry and Asatru she is honored as a goddess of youth, renewal, and the vitality of the natural world. Her myth has inspired poets and artists across Scandinavia and beyond, and she appears in retellings of Norse mythology from Richard Wagner's opera cycle to contemporary fantasy literature, usually as a figure whose gentleness conceals an indispensable strength.
