It was a beautiful great dress of brown feathers and gray, and in it Freia loved to skim like a falcon among the clouds and stars. Loki put it on, and when he had done so he looked exactly like a great brown hawk. Only his bright black eyes remained the same, glancing here and there, so that they lost sight of nothing. With a whirr of his wings Loki flew off to the north, across mountains and valleys and the great river Ifing, which lay between Asgard and Giant Land. And at last he came to the palace of Thiasse the giant. It happened, fortunately, that Thiasse had gone fishing in the sea, and Idun was left alone, weeping and broken-hearted. Presently she heard a little tap on her window, and, looking up, she saw a great brown bird perching on the ledge. He was so big that Idun was frightened and gave a scream. But the bird nodded pleasantly and croaked: "Don't be afraid, Idun. I am a friend. I am Loki, come to set you free." "Loki! Loki is no friend of mine. He brought me here," she sobbed. "I don't believe you came to save me." "That is indeed why I am here," he replied, "and a dangerous business it is, if Thiasse should come back before we start for home." "How will you get me out?" asked Idun doubtfully. "The door is locked, and the window is barred." "I will change you into a nut," said he, "and carry you in my claws." "What of the casket of apples?" queried Idun. "Can you carry that also?" Then Loki laughed long and loudly. "What welcome to Asgard do you think I should receive without the apples?" he cried. "Yes, we must take them, indeed." Idun came to the window, and Loki, who was a skillful magician, turned her into a nut and took her in one claw, while in the other he seized the casket of apples. Then off he whirred out of the palace grounds and away toward Asgard's safety. In a little while Thiasse returned home, and when he found Idun and her apples gone, there was a hubbub, you may be sure! However, he lost little time by smashing mountains and breaking trees in his giant rage; that fit was soon over. He put on his eagle plumage and started in pursuit of the falcon. Now an eagle is bigger and stronger than any other bird, and usually in a long race he can beat even the swift hawk who has an hour's start. Presently Loki heard behind him the shrill scream of a giant eagle, and his heart turned sick. But he had crossed the great river, and already was in sight of Asgard. The aged Æsir were gathered on the rainbow bridge watching eagerly for Loki's return; and when they spied the falcon with the nut and the casket in his talons, they knew who it was. A great cheer went up, but it was hushed in a moment, for they saw the eagle close after the falcon; and they guessed that this must be the giant Thiasse, the stealer of Idun.
