In the country of Zouman, in Persia, there lived a Greek king. This king was a leper, and all his doctors had been unable to cure him, when a very clever physician came to his court.

He was very learned in all languages, and knew a great deal about herbs and medicines.

As soon as he was told of the king's illness he put on his best robe and presented himself before the king. "Sire," said he, "I know that no physician has been able to cure your majesty, but if you will follow my instructions, I will promise to cure you without any medicines or outward application."

The king listened to this proposal.

"If you are clever enough to do this," he said, "I promise to make you and your descendants rich for ever."
