Mythology fo eye, representations in art

India: "In an early story Purusha is a primal man sacrificed by the gods as the act of creation. The sky comes from his head, the earth from his feet, the sun from his eye and the moon from his mind."

China: "After all this effort P'an Ku falls to pieces. His limbs become the mountains, his blood the rivers, his breath the wind and his voice the thunder. His two eyes are the sun and the moon. The parasites on his body are mankind."
