day sky.  The two vestibules were places of gloom and semi-darkness, and the ten divisions of the Tuat were covered by black night.  When the Sun-god set in the west in the evening he was obliged to travel through the Tuat to the eastern sky, in order to rise again on this earth on the following day.  He entered the Tuat at or near Thebes, proceeded northwards, through the under-worlds of Thebes, Abydos, Herakleopolis, Memphis, and Sais, then turned towards the east and crossed the Delta, and, having passed through the underworld of Heliopolis, appeared in the eastern sky to resume his daily course from east to west.  His journey so far as Memphis he made in a boat, which sailed on the river of the Tuat.  At Memphis he left the boat on the river, and entered a magical boat formed of a serpent’s body, and so passed under the mountainous district round about Sakkarah.  At or near Sais he returned to his river boat, and sailing over the great marine lakes of the Delta reached Heliopolis.  The sun-god was guided through each section of the Tuat by a goddess who belonged to the district, and for the sake of uniformity the journey through each section was supposed to occupy an hour; the guiding goddess left the god’s boat at the end of her hour, and the goddess of the next section took her place.  The path of the god was lighted by fire, which the beings who lived in the various sections poured out of their mouths, and the attendant gods who were with them in his boat spake words of power, which overcame all opposition and removed every obstacle.  As he passed through each section it was temporarily lighted up by the fire already mentioned, and he uttered words of power, the effect of which was to supply the inhabitants of the section with air, food, and drink, sufficient to last until the next night, when he would renew the supply.  Many parts of the Tuat were filled with hideous monsters in human and animal forms, and with evil spirits of every kind, but they were all rendered powerless by the spells uttered by the gods who were in attendance on the Sun-god in his boat.  At one time in the history of Egypt it became the earnest wish of every pious man to make the journey from this world to the next in the Boat of the Sun.  Armed with words of power and amulets of all kinds, and relying on their lives of moral rectitude, and the effect of the offerings which they had made to the dead, their souls entered the Boat, and set out on their journey.  When they reached Abydos their credentials were examined, and those who were found to be speakers of the truth and upright in their actions were allowed to continue their journey with the Sun-god, and to live with him ever after.  Some souls preferred to remain at Abydos and to live with Osiris, and those who were found righteous in the Judgment were allowed to do so, and were granted estates in perpetuity in the kingdom of this god.  The Book “AM TUAT” describes the sections of the Tuat and their inhabitants, and supplies all the information which the soul was supposed to require in passing from this world to the next.  Many copies of certain sections of it are known, and some of these are in the British Museum;[1] the most complete copy of it is in the tomb of Seti I at Thebes.
