In The Days of Giants A Book of Norse Tales
Page: 21Then a strange thing happened. As the great bird flapped upward with his prey, giving a scream of malicious laughter, the pole which Loki still held stuck fast to the eagle's back, and Loki was unable to let go of the other end.
56 "Help, help!" he shouted to Odin and to Hœnir, as he felt himself lifted off his feet. But they could not help him. "Help, help!" he screamed, as the eagle flew with him, now high, now low, through brush and bog and briar, over treetops and the peaks of mountains. On and on they went, until Loki thought his arm would be pulled out, like a weed torn up by the roots. The eagle would not listen to his cries nor pause in his flight, until Loki was almost dead with pain and fatigue.
"Hark you, Loki," screamed the eagle, going a little more slowly; "no one can help you except me. You are bewitched, and you cannot pull away from this pole, nor loose the pole from me, until I choose. But if you will promise what I ask, you shall go free."
Then Loki groaned: "O eagle, only let me go, and tell me who you really are, and I will promise whatever you wish."
The eagle answered: "I am the giant Thiasse, the enemy of the Æsir. But you ought to love me, Loki, for you yourself married a giantess."
"I want this," quoth Thiasse gruffly. "I am growing old, and I want the apples which Idun keeps in her golden casket, to make me young again. You must get them for me."
Now these apples were the fruit of a magic tree, and were more beautiful to look at and more delicious to taste than any fruit that ever grew. The best thing about them was that whoever tasted one, be he ever so old, grew young and strong again. The apples belonged to a beautiful lady named Idun, who kept them in a golden casket. Every morning the Æsir came to her to be refreshed and made over by a bite of her precious fruit. That is why in Asgard no one ever waxed old or ugly. Even Father Odin, Hœnir, and Loki, the three travelers who had seen the very beginning of everything, when the world was made, were still sturdy and young. And so long as Idun kept her apples safe, the faces of the family who sat about the table of Valhalla would be rosy and fair like the faces of children.
"O friend giant!" cried Loki. "You know58 not what you ask! The apples are the most precious treasure of Asgard, and Idun keeps watch over them as if they were dearer to her than life itself. I never could steal them from her, Thiasse; for at her call all Asgard would rush to the rescue, and trouble would buzz about my ears like a hive of bees let loose."
