At the rear stood the young king's servant, faithful Heinrich. Faithful Heinrich had been so saddened by his master's transformation into a frog that he had had to place three iron bands around his heart to keep it from bursting in grief and sorrow. The carriage was to take the king back to his kingdom. Faithful Heinrich lifted them both inside and took his place at the rear. He was filled with joy over the redemption. After they had gone a short distance, the prince heard a crack from behind, as though something had broken.
He turned around and said, "Heinrich, the carriage is breaking apart."
No, my lord, the carriage it's not,
But one of the bands surrounding my heart,
That suffered such great pain,
When you were sitting in the well,
When you were a frog.
Once again, and then once again the prince heard a cracking sound and thought that the carriage was breaking apart, but it was the bands springing from faithful Heinrich's heart because his master was now redeemed and happy.
