Amduat. 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 and the sun god, in the boat dragged by four gods, holds a serpent to control them. A sarcophagus proceeds downwards. Images and texts are executed in italics imitating funerary papyri.
