When Set was destroyed Osiris departed from this world to the kingdom which the gods had given him and began to reign over the dead. He was absolute king of this realm, just as Ra the Sun-god was absolute king of the sky. This region of the dead, or Dead-land, is called "Tat," or "Tuat," but where the Egyptians thought it was situated is not quite clear. The original home of the cult of Osiris was in the Delta, in a city which in historic times was called Tetu by the Egyptians and Busiris by the Greeks, and it is reasonable to assume that the Tuat, over which Osiris ruled, was situated near this place. Wherever it was it was not underground, and it was not originally in the sky or even on its confines; but it was located on the borders of the visible world, in the Outer Darkness. The Tuat was not a place of happiness, judging from the description of it in the PER-T EM HRU, or Book of the Dead. When Ani the scribe arrived there he said, "What is this to which I have come? There is neither water nor air here, its depth is unfathomable, it is as dark as the darkest night, and men wander about here helplessly. A man cannot live here and be satisfied, and he cannot gratify the cravings of affection" (Chapter CLXXV). In the Tuat there was neither tree nor plant, for it was the "land where nothing grew"; and in primitive times it was a region of destruction and death, a place where the dead rotted and decayed, a place of abomination, and horror and terror, and annihilation. But in very early times, certainly in the Neolithic Period, the Egyptians believed in some kind of a future life, and they dimly conceived that the attainment of that life might possibly depend upon the manner of life which those who hoped to enjoy it led here. The Egyptians "hated death and loved life," and when the belief gained ground among them that Osiris, the God of the Dead, had himself risen from the dead, and had been acquitted by the gods of heaven after a searching trial, and had the power to "make men and women to be born again," and "to renew life" because of his truth and righteousness, they came to regard him as the Judge as well as the God of the Dead. As time went on, and moral and religious ideas developed among the Egyptians, it became certain to them that only those who had satisfied Osiris as to their truth-speaking and honest dealing upon earth could hope for admission into his kingdom.
