A Journey to the End of the Universe

 
"Nana Buluku, the Great Mother, created the world. She had twins, Mawu and Lisa. She did nothing after that. Mawu was the moon who had power over the night and lived in the west. Lisa was the sun, who made his home in the east. At first, Mawu and Lisa had no offspring. But then, when there was an eclipse --- when one of them was in the shadow of the other or another heavenly body --- they came together and created children.

Creation Myth of the Abomey (Republic of Benin, Africa) from about the 12th century.
