Then Father Odin, who sat on his high throne, looking very tired and sad, said: “Oh, Loki, what is this that you have done? You have broken your promise of brotherhood, and brought sorrow upon Asgard! Fail not to bring home again our sister, or else come not yourself within our gates!”
Loki knew well that this command must be obeyed, and besides, even he was beginning to wish for Iduna again; so, borrowing the cloak of falcon feathers which belonged to the goddess Freyja, he put it on and set out for Utgard and the castle of the giant Thiassi, which was a gloomy cave in a high rock by the sea, and there he found poor Iduna shut up in prison.
By good luck, the giant was away fishing when Loki arrived, so he was able to fly in, without being seen, through the narrow opening in Iduna’s rock cell. You would have taken him to be just a falcon bird, but Iduna knew it was really Loki, and was filled with joy to see him. Without stopping to talk, Loki quickly changed her into a nut, which he held fast in his falcon claws, and flew swiftly northward, over the sea, toward Asgard. He had not gone far when he heard a rushing noise behind them, and he knew it must be the eagle. Faster and faster flew the falcon with his precious nut; but the fierce eagle flew still faster after them.
Meanwhile, for five days, the dwellers in Asgard gathered together on the city walls, gazing southward, to watch for the coming of the birds, while Loki and Iduna, chased by Thiassi, the eagle, flew over the wide sea separating Utgard, the land of the giants, from Asgard. Each night the eagle was nearer his prey, and the watchers in the city were filled with fear lest he should overtake their friends.
At last they thought of a plan to help Iduna: gathering a great pile of wood by the city walls, they set fire to it. When Loki reached the place he flew safely through the thick smoke and flame, for you know he was the god of fire, and dropped down into the city with his little nut held fast in his falcon claws. But when the heavy eagle came rushing on after them, he could not rise above the heat of the fire, and, smothered by the smoke, fell down and was burned to death.
There was great joy in Asgard at having the dear Iduna back again; her friends gathered around her, and she invited them all into her garden, where the withered trees and flowers began to sprout and blossom; the gay birds came back, singing and building their nests, and the happy little brooks went dancing under the trees.
Iduna sat with Bragi among her friends, and they all feasted upon her golden apples; she was so thankful to be free, and at home in her garden again. Once more the Æsir became young and strong, and the two dark strangers went away, for happiness and peace had come back to Asgard.
While Iduna’s friends were still crowding about her, all joyful and glad at getting her home again, they spied some one afar off, coming toward Asgard.
