Once upon a time...
There was a king whose only child was a girl. Now the King had been very anxious to have a son, or at least a grandson, to come after him, but he was told by a prophet whom he consulted that his own daughter's son should kill him. This news terrified him so much that he determined never to let his daughter be married, for he thought it was better to have no grandson at all than to be killed by his grandson. He therefore called his workmen together, and bade them dig a deep round hole in the earth, and then he had a prison of brass built in the hole, and then, when it was finished, he locked up his daughter.

No man ever saw her, and she never saw even the fields and the sea, but only the sky and the sun, for there was a wide open window in the roof of the house of brass. So the Princess would sit looking up at the sky, and watching the clouds float across, and wondering whether she should ever get out of her prison. Now one day it seemed to her that the sky opened above her, and a great shower of shining gold fell through the window in the roof, and lay glittering in her room. Not very long after, the Princess had a baby, a little boy, but when the King her father heard of it he was very angry and afraid, for now the child was born that should be his death. Yet, cowardly as he was, he had not quite the heart to kill the Princess and her baby outright, but he had them put in a huge brass-bound chest and thrust out to sea, that they might either be drowned or starved, or perhaps come to a country where they would be out of his way.
So the Princess and the baby floated and drifted in the chest on the sea all day and night, but the baby was not afraid of the waves nor of the wind, for he did not know that they could hurt him, and he slept quite soundly. And the Princess sang a song over him, and this was her song:
"Child, my child, how sound you sleep! Though your mother's care is deep, You can lie with heart at rest In the narrow brass-bound chest; In the starless night and drear You can sleep, and never hear Billows breaking, and the cry Of the night-wind wandering by; In soft purple mantle sleeping With your little face on mine, Hearing not your mother weeping And the breaking of the brine."
Well, the daylight came at last, and the great chest was driven by the waves against the shore of an island. There the brass-bound chest lay, with the Princess and her baby in it, till a man of that country came past, and saw it, and dragged it on to the beach, and when he had broken it open, behold! there was a beautiful lady and a little boy. So he took them home, and was very kind to them, and brought up the boy till he was a young man. Now when the boy had come to his full strength the King of that country fell in love with his mother, and wanted to marry her, but he knew that she would never part from her boy. So he thou

ght of a plan to get rid of the boy, and this was his plan: A great Queen of a country not far off was going to be married, and this king said that all his subjects must bring him wedding presents to give her. And he made a feast to which he invited them all, and they all brought their presents; some brought gold cups, and some brought necklaces of gold and amber, and some brought beautiful horses; but the boy had nothing, though he was the son of a princess, for his mother had nothing to give him. Then the rest of the company began to laugh at him, and the King said: "If you have nothing else to give, at least you might go and fetch the Terrible Head."
The boy was proud, and spoke without thinking:
"Then I swear that I will bring the Terrible Head, if it may be brought by a living man. But of what head you speak I know not."
Then they told him that somewhere, a long way off, there dwelt three dreadful sisters, monstrous ogrish women, with golden wings and claws of brass, and with serpents growing on their heads instead of hair. Now these women were so awful to look on that whoever saw them was turned at once into stone. And two of them could not be put to death, but the youngest, whose face was very beautiful, could be killed, and it was her head that the boy had promised to bring. You may imagine it was no easy adventure.
When he heard all this he was perhaps sorry that he had sworn to bring the Terrible Head, but he was determined to keep his oath. So he went out from the feast, where they all sat drinking and making merry, and he walked alone beside the sea in the dusk of the evening, at the place where the great chest, with himself and his mother in it, had been cast ashore.
There he went and sat down on a rock, looking toward the sea, and wondering how he should begin to fulfil his vow. Then he felt some one touch him on the shoulder; and he turned, and saw a young man like a king's son, having with him a tall and beautiful lady, whose blue eyes shone like stars. They were taller than mortal men, and the young man had a staff in his hand with golden wings on it, and two golden serpents twisted round it, and he had wings on his cap and on his shoes. He spoke to the boy, and asked him why he was so unhappy; and the boy told him how he had sworn to bring the Terrible Head, and knew not how to begin to set about the adventure.
Then the beautiful lady also spoke, and said that "it was a foolish oath and a hasty, but it might be kept if a brave man had sworn it." Then the boy answered that he was not afraid, if only he knew the way.
Then the lady said that to kill the dreadful woman with the golden wings and the brass claws, and to cut off her head, he needed three things: first, a Cap of Darkness, which would make him invisible when he wore it; next, a Sword of Sharpness, which would cleave iron at one blow; and last, the Shoes of Swiftness

, with which he might fly in the air.
The boy answered that he knew not where such things were to be procured, and that, wanting them, he could only try and fail. Then the young man, taking off his own shoes, said: "First, you shall use these shoes till you have taken the Terrible Head, and then you must give them back to me. And with these shoes you will fly as fleet as a bird, or a thought, over the land or over the waves of the sea, wherever the shoes know the way. But there are ways which they do not know, roads beyond the borders of the world. And these roads have you to travel. Now first you must go to the Three Gray Sisters, who live far off in the north, and are so very cold that they have only one eye and one tooth among the three. You must creep up close to them, and as one of them passes the eye to the other you must seize it, and refuse to give it up till they have told you the way to the Three Fairies of the Garden, and THEY will give you the Cap of Darkness and the Sword of Sharpness, and show you how to wing beyond this world to the land of the Terrible Head."
Then the beautiful lady said: "Go forth at once, and do not return to say good-by to your mother, for these things must be done quickly, and the Shoes of Swiftness themselves will carry you to the land of the Three Gray Sisters --for they know the measure of that way."
So the boy thanked her, and he fastened on the Shoes of Swiftness, and turned to say good-by to the young man and the lady. But, behold! they had vanished, he knew not how or where! Then he leaped in the air to try the Shoes of Swiftness, and they carried him more swiftly than the wind, over the warm blue sea, over the happy lands of the south, over the northern peoples who drank mare's milk and lived in great wagons, wandering after their flocks. Across the wide rivers, where the wild fowl rose and fled before him, and over the plains and the cold North Sea he went, over the fields of snow and the hills of ice, to a place where the world ends, and all water is frozen, and there are no men, nor beasts, nor any green grass. There in a blue cave of the ice he found the Three Gray Sisters, the oldest of living things. Their hair was as white as the snow, and their flesh of an icy blue, and they mumbled and nodded in a kind of dream, and their frozen breath hung round them like a cloud. Now the opening of the cave in the ice was narrow, and it was not easy to pass in without touching one of the Gray Sisters. But, floating on the Shoes of Swiftness, the boy just managed to steal in, and waited till one of the sisters said to another, who had their one eye:
"Sister, what do you see? do you see old times coming back?"
"No, sister."
"Then give ME the eye, for perhaps I can see farther than you."
Then the first sister passed the eye to the second, but as the second groped for it the boy caught i

t cleverly out of her hand.
"Where is the eye, sister?" said the second grey woman.
"You have taken it yourself, sister," said the first grey woman.
"Have you lost the eye, sister? have you lost the eye?" said the third grey woman; "shall we NEVER find it again, and see old times coming back?"
Then the boy slipped from behind them out of the cold cave into the air, and he laughed aloud.
When the grey women heard that laugh they began to weep, for now they knew that a stranger had robbed them, and that they could not help themselves, and their tears froze as they fell from the hollows where no eyes were, and rattled on the icy ground of the cave. Then they began to implore the boy to give them their eye back again, and he could not help being sorry for them, they were so pitiful. But he said he would never give them the eye till they told him the way to the Fairies of the Garden.
Then they wrung their hands miserably, for they guessed why
