Silk of Kings
The Khan respected the artisan and his skill, and said he would consent to the man's wishes if he created something more beautiful and wonderful than his daughter in the course of one night. The artisan struggled with this throughout the night, and as morning broke, had not succeeded.
At dawn, he sat by a stream, lamenting the loss of his daughter, when suddenly, reflected in the blue water he saw all the colors of sunrise, clouds, and a rainbow, and knew what he had to do.
From this incredible vision, he created a silk that was unsurpassed in beauty and originality. He brought a piece of the fabric to the Khan. And the Khan could not help but agree that the fabric was more wonderful than the artisan's daughter, and agreed to rescind his marriage proposal.
From this legend, the silk of the Ferghana Valley received its name, "Khan-Atlas", or "Silk of Kings".
