The Frog-King, or Iron Henry

Then they went to sleep, and next morning when the sun awoke them, a carriage came driving up with eight white horses, which had white ostrich feathers on their heads, and were harnessed with golden chains, and behind stood the young King's servant faithful Henry. Faithful Henry had been so unhappy when his master was changed into a frog, that he had caused three iron bands to be laid round his heart, lest it should burst with grief andsadness. The carriage was to conduct the young King into his kingdom. Faithful Henry helped them both in, and placed himself behind again, and was full of joy because of this deliverance. And when they had driven a part of the way, the King's son heard a cracking behind him as if something had broken. So he turned round and cried, "Henry, the carriage is breaking."

"No, master, it is not the carriage. It is a band from my heart, which was put there in my great pain when you were a frog and imprisoned in the well." Again and once again while they were on their way something cracked, and each time the King's son thought the carriage was breaking; but it was only the bands which were springing from the heart of faithful Henry because his master was set free and was happy.
