Buto was a cobra-goddess whose original home and cult center was in the Delta of the Nile at Per-Uatchit. In time she became a prominent protectress of all of Lower Egypt. As such she was routinely connected to the goddess of Upper Egypt, Nekhebet. Together, they appeared in many pieces of art as symbols of the Two Lands, a united Egypt.
It is thought perhaps that her powers could be used against the pharaoh as well. Her bite may have been the deadly device used by Anubis at the appointed time of the pharaoh's death. cobra first worn on the brow of Buto was a personification of the sun's burning heat and she was called the "Lady of Heaven" and the queen of all of the gods.
She was closely associated with Horus the Elder, who was the protector god of Lower Egypt. Also she was associated with Harpokrates (Horus the Younger); she protected him from Seth in the marshes of the Delta while Isis was searching for the body of Osiris.
