In the Charles Perrault fairy tale “Peau d’Âne” a young princess, whose kingdom’s riches are dependant on a gold excreting donkey, orders the impossible from her doting stepfather to thwart marrying him: three dresses made of immaterial materials. The first is to be made of the “sky” and should be as light and airy as the clouds. The second is to be made of “moonbeams” and should reflect the same lyrical intensity as the moon at night. The third, and last, is to be made of “sunlight” and should be as blinding and warm as the sun above.
