Iron John

There was once on a time a King who had a great forest near his palace, full of all kinds of wild animals. One day he sent out a huntsman to shoot him a roe, but he did not come back. "Perhaps some accident has befallen him," said the King, and the next day he sent out two more huntsmen who were to search for him, but they too stayed away. Then on the third day, he sent for all his huntsmen, and said, "Scour the whole forest through, and do not give up until ye have found all three." But of these also, none came home again, and of the pack of hounds which they had taken with them, none were seen more. From that time forth, no one would any longer venture into the forest, and it lay there in deep stillness and solitude, and nothing was seen of it, but sometimes an eagle or a hawk flying over it. This lasted for many years, when a strange huntsman announced himself to the King as seeking a situation, and offered to go into the dangerous forest. The King, however, would not give his consent, and said, "It is not safe in there; I fear it would fare with thee no better than with the others, and thou wouldst never come out again." The huntsman replied, "Lord, I will venture it at my own risk, of fear I know nothing."
The huntsman therefore betook himself with his dog to the forest. It was not long before the dog fell in with some game on the way, and wanted to pursue it; but hardly had the dog run two steps when it stood before a deep pool, could go no farther, and a naked arm stretched itself out of the water, seized it, and drew it under, When the huntsman saw that, he went back and fetched three men to come with buckets and bale out the water. When they could see to the bottom there lay a wild man whose body was brown like rusty iron, and whose hair hung over his face down to his knees. They bound him with cords, and led him away to the castle. There was great astonishment over the wild man; the King, however, had him put in an iron cage in his court-yard, and forbade the door to be opened on pain of death, and the Queen herself was to take the key into her keeping. And from this time forth every one could again go into the forest with safety.

The King had a son of eight years, who was once playing in the court-yard, and while he was playing, his golden ball fell into the cage. The boy ran thither and said, "Give me my ball out." - "Not till thou hast opened the door for me," answered the man. "No," said the boy, "I will not do that; the King has forbidden it," and ran away. The next day he again went and asked for his ball; the wild man said, "Open my door," but the boy would not. On the third day the King had ridden out hunting, and the boy went once more and said, "I cannot open the door even if I wished, for I have not the key." Then the wild man said, "It lies under thy mother's pillow, thou canst get it there." The boy, who wanted to have his ball back, cast all thought to the winds, and brought the key. The door opened with difficulty, and the boy pinched his fingers. When it was open the wild man stepped out, gave him the golden ball, and hurried away. The boy had become afraid; he called and cried after him, "Oh, wild man, do not go away, or I shall be beaten!" The wild man turned back, took him up, set him on his shoulder, and went with hasty steps into the forest. When the King came home, he observed the empty cage, and asked the Queen how that had happened? She knew nothing about it, and sought the key, but it was gone. She called the boy, but no one answered. The King sent out people to seek for him in the fields, but they did not find him. Then he could easily guess what had happened, and much grief reigned in the royal court.
