A sacred symbol of Nut was the ladder used by Osiris to enter her heavenly skies.
Nut appears in the creation myth of Heliopolis which involves several goddesses who play important roles: Tefnut (Tefenet) is a personification of moisture, who mated with Shu (Air) and then gave birth to Sky as the goddess Nut, who mated with her brother Earth, as Geb.
