Idun gathered up the golden Apples and went out of Asgard, carrying with her all that made it heaven. No sooner was she beyond the gates than a mighty rushing sound was heard, like the coming of a tempest, and before she could think or act, the giant Thjasse, in his eagle plumage, was bearing her swiftly away through the air to his desolate, icy home in Thrymheim, where, after vainly trying to persuade her to let him eat the Apples and be forever young like the Gods, he kept her a lonely prisoner.
Loke, after keeping his promise and delivering Idun into the hands of the giant, strayed back into Asgard as if nothing had happened. The next morning, when the Gods assembled for their feast, there was no Idun. The day after day went past, and still, the beautiful Goddess did not come. Little by little the light of youth and beauty faded from the home of the Gods, and they themselves became old and haggard. Their strong, young faces were lined with care and furrowed by age, their raven locks passed from gray to white, and their flashing eyes became dim and hollow. Brage, the God of poetry, could make no music while his beautiful wife was gone he knew not whither.
Morning after morning the faded light broke on paler and ever paler faces until even in heaven the eternal light of youth seemed to be going out forever. Finally, the Gods could bear the loss of power and joy no longer. They made a rigorous inquiry. They tracked Loke on that fair morning when he led Idun beyond the gates; they seized him and brought him into solemn council, and when he read in their haggard faces the deadly hate which flamed in all their hearts against his treachery, his courage failed, and he promised to bring Idun back to Asgard if the Goddess Freyja would lend him her falcon-guise. No sooner said than done; and with an eager gaze, the Gods watched him as he flew away, becoming at last only a dark moving speck against the sky.
