"That is it! I hear it, the Song of Spring!" And as the glass mender came into the room with his basket and his tools, she said: "At last you've come! You've cured me, and I am now quite well again."

There was no doubt about it. Rainbow from that moment was cured, and the glass mender went to the King and claimed his reward.

The Blue Rose Fairy Book — Part 6

At first the King was vexed that his daughter should have to wed a humble glass mender, but he did not dare play any tricks with his daughter's life after what had happened, for fear she should fall ill again; and besides, Rainbow was determined to marry him, and as he was so young, so handsome, and so well-spoken, the King told the Queen that he was very likely a Prince in disguise.

But the glass mender made two conditions about his marriage: the first was that he was to continue to be a wandering glass mender who earned his living by going from city to city, and from village to village, mending glass, and the second was that Rainbow was never to ask him where he came from nor who were his parents, and that she should call him Blue Eyes, nor ever ask him whether he had another name.

This convinced the King that Blue Eyes was a Prince in disguise, and the conditions were readily agreed to, and Rainbow and Blue Eyes were married without further delay. The King gave them each a white pony for a wedding present and they started off on their travels.

They rode through the fields and the woods, from village to village, sleeping now in a house and now out of doors, and for the first time in her life Rainbow tasted and saw the Spring; and no words can tell how happy they were: all day long Blue Eyes played a tune on his glass pipe, and he showed Rainbow the haunts of the birds and the beasts; and whenever they came to a village it was as though they brought the sunshine of the morning with them, for as soon as any one looked at Blue Eyes, they could not help being happy, and when he played on his pipe people danced for joy. They wandered over the wide world, and they saw every kind of country and city, and wherever they went smiling faces met them and they made sad people happy, and happy people happier still.

When they were in the woods or meadows the birds and beasts seemed to know Blue Eyes, and he talked with them just as if they were real people; and the most savage beasts--wolves and bears and wild boars--were as tame as lap-dogs when he spoke to them; and the nightingales used to perch on Blue Eyes' shoulder in the evening, and sing, as he rode with Rainbow through the forest; the bees and butterflies used to fly in front of them and show them the way.
