Many, many thousand years ago there lived a mighty King whom heaven had blessed with a clever and beautiful son. When he was only ten years old the boy was cleverer than all the King’s counsellors put together, and when he was twenty he was the greatest hero in the whole kingdom. His father could not make enough of his son, and always had him clothed in golden garments which shone and sparkled like the sun; and his mother gave him a white horse, which never slept, and which flew like the wind. All the people in the land loved him dearly, and called him the Sun-Hero, for they did not think his like existed under the sun. Now it happened one night that both his parents had the same extraordinary dream. They dreamt that a girl all dressed in red had come to them and said: ‘If you wish that your son should really become the Sun-Hero in deed and not only in name, let him go out into the world and search for the Tree of the Sun, and when he has found it, let him pluck a golden apple from it and bring it home.’

He knocked at the door, which was opened noiselessly and by invisible hands. Finding no one about, the Prince rode on, and came to a great meadow, where the Sun-Tree grew. When he reached the tree he put out his hand to pick a golden apple; but all of a sudden the tree grew higher, so that he could not reach its fruit. Then he heard some one behind him laughing. Turning round, he saw the girl in red walking towards him, who addressed him in these words:

‘Do you really imagine, brave son of the earth, that you can pluck an apple so easily from the Tree of the Sun? Before you can do that, you have a difficult task before you. You must guard the tree for nine days and nine nights from the ravages of two wild black wolves, who will try to harm it. Do you think you can undertake this?’
