At these words Kullervo jumped up and did as the raven had said. And when the sun was setting in the west, Kullervo hastened homeward, driving bears and wolves before him, but by a magic spell he made them look like cattle. And as he went, he said to them: 'Seize my hateful mistress when she comes to milk the cattle, and tear and rend her in pieces.' And he took a cow-horn and made a bugle of it and blew till the hills rang, to announce his return.
When he reached the cow-yard, Ilmarinen's wife greeted him joyfully, for it was late and she had feared that something had happened. And she told her oldest maid-servant to go and milk the cows as she herself was busy. But Kullervo said: 'Thou shouldst go thyself, for the cows are in better condition to-night than they have ever been before.' And so she went, and when she saw them she cried out in wonder: 'Truly my cattle are beautiful to-night, for their hair glistens like the fur of lynxes, and is soft as ermine skin.'
With these words she seated herself to begin milking, but all at once the wolves and bears appeared in their true shapes and began to tear her to pieces. Then she cried out to Kullervo, when she saw what he had done, but he answered: 'If I have done evil thou hast done still greater evil, for thou hast baked a stone inside my bread, and I have broken on it my knife, the only relic of my mother's people.'
Then Ilmarinen's wife began to beg him to aid her, and promised him the best of everything to eat, and that he should never have to work again. But Kullervo would not listen to her prayers, but rejoiced at her agony, and then the wolves and bears made one more onset, and she fell and died. Such was the end of the beauteous Rainbow-maiden, for whom so many had wooed, and who had become the pride and joy of Kalevala.
Then Kullervo hastened off, before Ilmarinen should come home and find out what had happened. And after he was at a safe distance he began to play upon the bugle he had made, until Ilmarinen ran out of his smithy to see who it could be, and there before him in the courtyard Ilmarinen saw the body of his wife and learned what had happened: and he sat down and wept bitterly, for all the joy of his life was now gone from him.
