The Goddess Wadjet (Green One) was the Protector of Lower Egypt. She was also the protector of kings and of women in childbirth. As a patron Goddess, she was associated with the land and depicted as a snake-headed woman or a snake—usually an Egyptian cobra. She was shown coiled upon the head of Ra; in order to act as his protection. That is why the Pharaoh's crown showed a rearing cobra.
