Parable of the Sultan with an ugly wife

A very long story in one parable:

In order to become Sultan, a young prince was forced to marry the daughter of a rich caravaner. The young wife was widely believed to be ugly because she was so skinny. In those days the Sultan then commanded that all women in the village be covered in public. In this way, he would not have to look at the beautiful fat wives of the other important men, and no one would be able to see that his wife was thin.
Even today, when you visit this village, the Sultan with the ugly wife will kill any woman who is not covered with cloth, head to foot. It is said that the ugly wife had many ugly daughters, all of them so thin and tall that they walk swaying and tinkling bells like camels. And they all married and had many children. Of course, no one knows how ugly they are, because they are never seen.
The men with beautiful wives beat their foreheads with frustration: No one knows how lucky they are. No one knows how lucky any man is, when he is with a woman no one can ever see.
