A long time ago there were a king and queen who were unhappy because they were childless. But it happened that one when the queen was bathing, a frog crept out of the water on to the land, and said to her, “Your wish shall e fulfilled, before a year has goen by, you shall have a daughter”.

What the frog had said came true, and the queen had a little girl who was so pretty that the king could not contain himself for joy, and orderd a great feast. He invited not only his kindred, friends and accquaintances, but also the wise women, in order that they might be kind and well disposed towards the chill. There were thirteen of them in his kingdom, but, as he had only twelve golden pates for them to eat out of, one of them had to be left at home.

The feast was held with all manager of splendor and when it came to an end the wise women bestowed their magic gifts upon the baby – one gave virtue, another beauty, a third riches, and so on with everything in the world that one can wish for.
