The Twins. Portrayed in most emergence or creation stories. The twins are usually shown as boys or short men who overcame great odds to defend the people from all enemies, drought, attack from other beings, animals, or many other problems. They illustrate the concept of duality in life. In the natural world everything exists in balance: male & female, large & small, light & dark & good & evil. Here they are depicted as Father Sky & Mother Earth from a Navajo sand painting
