Fourth hour. The sun boat, transformed into a serpent, is in a vast desert, the Land of Sokar, lord of the Rosetau and funerary form of Osiris. The desert is populated by gigantic serpents. Here the scorpion Ankhet and a huge uraeus stand before a god who makes offerings to the serpent. Behind him is a winged serpent with three heads and two pairs of human legs. Below, the god Aptuat holds a sceptre and stands before a serpent with two heads.
