Estsanatlehi

According to the Navajo Native Americans, Estsanatlehi, whose name means "Changing Woman", created the first man and woman from pieces of her own skin. She is the wife of the Sun god, Tsohanoai.

Her home is in the far west. She meets her husband, the Sun god Tsohanoai, every night as he sets. It is also believed she becomes old each winter and young each spring, just as the Earth does with the changing seasons.
