Before the king set out afresh on his travels Aveline had restored to him his horse and his sword, and though these were but small consolation for the absence of the princess, they were better than nothing, for he felt that somehow they might be the means of leading him back to her.
After crossing several deserts the king arrived at length in a country that seemed inhabited, but the instant he stepped over the border he was seized and flung into chains, and dragged at once to the capital. He asked his guards why he was treated like this, but the only answer he got was that he was in the territory of the Iron King, for in those days countries had no names of their own, but were called after their rulers.
The young man was led into the presence of the Iron King, who was seated on a black throne in a hall also hung with black, as a token of mourning for all the relations whom he had put to death.
'What are you doing in my country?' he cried fiercely.
'I came here by accident,' replied Souci, 'and if I ever escape from your clutches I will take warning by you and treat my subjects differently.'
'Do you dare to insult me in my own court?' cried the king. 'Away with him to Little Ease!'
Now Little Ease was an iron cage hung by four thick chains in the middle of a great vaulted hall, and the prisoner inside could neither sit, nor stand, nor lie; and, besides that, he was made to suffer by turns unbearable heat and cold, while a hundred heavy bolts kept everything safe. Girouette, whose business it was to see after Souci, had forgotten his existence in the excitement of some new idea, and he would not have been alive long to trouble anybody if Aveline had not come to the rescue and whispered in his ear, 'And the skein of thread?' He took it up obediently, though he did not see how it would help him but he tied it round one of the iron bars of his cage, which seemed the only thing he could do, and gave a pull. To his surprise the bar gave way at once, and he found he could break it into a thousand pieces. After this it did not take him long to get out of his cage, or to treat the closely barred windows of the hall in the same manner. But even after he had done all this freedom appeared as far from him as ever, for between him and the open country was a high wall, and so smooth that not even a monkey could climb it. Then Souci's heart died within him. He saw nothing for it but to submit to some horrible death, but he determined that the Iron King should not profit more than he could help, and flung his precious thread into the air, saying, as he did so, 'O fairy, my misfortunes are greater than your power. I am grateful for your goodwill, but take back your gift!' The fairy had pity on his youth and want of faith, and took care that one end of the thread remained in his hand. He suddenly felt a jerk, and saw that the thread must have caught on something, and this thought filled him with the daring that is born of despair. 'Better,' he said to himself, 'trust to a thread than to the mercies of a king;' and, gliding down, he found himself safe on the other side of the wall. Then he rolled up the thread and put it carefully into his pocket, breathing silent thanks to the fairy.
