The snake-goddess of the ancient Egyptian oracle in Buto and tutelary goddess of Lower Egypt (the Delta of the Nile).

She is the protector of the Egyptian king, together with the vulture-goddess Nekhbet.
She was placed as an uraeus (cobra amulet) on the crown of the king.
Her name means 'the papyrus colored', referring to the green color of the cobra.
Buto gave nourishment to both children of Isis.

She was depicted as a woman, or as a cobra with the crown of Lower Egypt on its head. The Greeks identified her with the goddess Leto. She is also called Uto.
