We find other descriptions of the Duat in the _Book of Gates_ and the _Book of Him that is in the Duat_, in which is outlined the journey that the sun-god makes through the otherworld after he has set upon the earth-world. Immediately after sinking he takes the form of Osiris, which in this instance is that of a ram with a man's head. Coming to the antechamber of the Duat in the west, his entrance is heralded by songs of praise, raised by the Ape-gods, while serpents blow fire from their mouths by the light of which his Pilot-gods steer his craft. All the doors are thrown open, and the dead, revived by the earthly air which Osiris carries with him, come to life again for a brief hour. All the creatures of this portion of the Duat are provided with meat and drink by command of the god. Such of the dead as dwell here are those who have failed to pass the various tests for entrance to his court, and all that they exist for is the material comfort provided for them by the brief diurnal passage of the deity. When the sun, who in this form is known as Af Ra, reaches the entrance to the second part of the Duat, which is called Urnes, the gods of the first section depart from him, and do not again behold his face until the following night. At this point the boat of Af Ra is met by the boats of Osiris and his attendant gods, and in this place also Osiris desires that the dead should receive food, light, and air. Here he grapples with the serpents Hau and Neha-her, as do most sun-gods during the time of darkness, and, having overcome them, is led into the Field of the Grain-gods, where he reposes for a while. When there he hearkens to the prayers of the living on behalf of the dead, and takes account of the offerings made by them. Continuing his journey, he traverses the twelve sections of the Duat. In some of these we see what were probably quite separate realms of the dead, such as the Realm of Seker, a god who is perhaps of greater antiquity than Osiris. In this place his boat is useless, as there is no river in the gloomy kingdom of Seker, which appears completely alien to Osiris. He therefore repeats words of awful power, which compel the gods of the place to lead him by subterranean passages from which he emerges into Amhet, where is situated a stream of boiling water. But he is not out of the kingdom of Seker until he reaches the sixth section, where dwell the dead kings of Egypt and the 'Khu' or Spirit-souls. It is at this point of his journey that Af Ra turns his face toward the east and directs his course to the Mountain of the Sunrise; previous to this he has been journeying from the south to the north. In the seventh section he is joined by Isis and other deities, and here his path is obstructed by the wicked serpent Apep, through whose body the attendant deities drive their daggers. A company of gods tow him through the eighth section, but his vessel sails itself through the ninth, and in the tenth and eleventh he seems
