In the fourth hour of the Amduat, Re enters a dark and dry new region called Rosetau, meaning ‘act of towing’. His solar barque, transformed into a double-headed serpent, is depicted as being towed by four gods over a dry, sandy land populated by snakes. Through a zigzag path, repeatedly blocked by doors, Re enters the ‘Land of Sokar, who is upon his sand’, which he visits during the fourth and fifth hours.
