Time passed merrily in the large town which was his capital; strangers arrived every day at the court. One day, two rogues, calling themselves weavers, made their appearance. They gave out that they knew how to weave stuffs of the most beautiful colors and elaborate patterns, the clothes manufactured from which should have the wonderful property of remaining invisible to everyone who was unfit for the office he held, or who was extraordinarily simple in character.
So the two pretended weavers set up two looms, and affected to work very busily, though in reality they did nothing at all. They asked for the most delicate silk and the purest gold thread; put both into their own knapsacks; and then continued their pretended work at the empty looms until late at night.
