I love this picture by Susan Seddon Boulet. In a book of her paintings I found it and on the same page this poem from the Navajo.

Soon feeling the darkness,
Yolkai Estan formed a circle,
    shaping it of turquoise and white shells.
Over this She held a rock of crystal,
    held it until a fire burst forth,
    a blaze that grew so hot, so bright.
    that with the help of the Holy People,
White Shell Woman pushed it further and further away,
    higher and higher into the spaces of heaven.
So it happened that Yolkai Estan,
She who had been born at the time of trouble,
She who had arrived attended by rainbows,
    brought light to the Earth.
