Nun, god of the primeval waters, origin of all life and chaos, lifts the barque of the sun god Re (represented by both the scarab and the sun disk) into the sky at the beginning of time. Nut, goddess of the Sky, is hanging from above, holding the god Osiris, also hanging from upside down, who holds the sun from above. This union, between the sun and Osiris, represents a solid eternal union between the soul and the body which meant to be a complete resurrection of the human being.
