in Greek mythology, female personification of night but also a great cosmogonical figure, feared even by Zeus, the king of the gods. According to one tradition, she was the daughter of Chaos and the mother of numerous primordial powers, including Sleep and Death. Another tradition made her the daughter and successor of Phanes, a creator god; she continued to advise her own successors (Uranus, her son by Phanes; Cronus, youngest son of Uranus; and Zeus) by means of her oracular gifts. Throughout antiquity she caught the imagination of poets and artists but was seldom worshiped.
