The Egyptian imagination spared no effort to represent with the greatest possible precision those mysterious regions where the soul had to undergo its appointed tests. Such beliefs afforded a wide scope for the individual influence of the artist and the poet, and accordingly we find that they were modified with a rapidity which is unique in Egyptian art. But the Egyptians were accustomed, from such early times, to give a concrete form to all their ideas, that they were sure to clothe the plastic expression of this theme in a richness and brilliancy of colour which we do not find to the same degree in any other people of antiquity. On the other hand, although they did not escape the operation of the eternal law of change, their temperament was sufficiently conservative to give to each of their creations a peculiar fixity and consistency. Their _Hades_, if we may call it so, took on a very definite form, and features which varied but little through a long course of centuries; and this form is practically that which we find in the sepulchres of the great Theban kings and in some belonging to private individuals. [Illustration: FIG. 185.--Anubis, in a funerary pavilion; from a bas-relief. (_Description de l'Égypte_, i., pl. 74.)] It was through long and gloomy galleries, like those of the σύριγξ, that the perilous voyage of the soul had to be undertaken. A boat carried it over the subterranean river, for in a country which had the Nile for its principal highway, every journey, even that of the sun through space, was looked upon as a navigation. Spacious saloons were imagined to exist among those galleries, chambers where the infernal gods and their acolytes sat enthroned in all the majesty of their office; and so the passages of the tomb were expanded here and there into oblong or square chambers, their roofs supported by pillars left in the living rock. On either side of the audience chambers the imagination placed narrow passes and defiles, in which the walls seemed to close in upon the soul and bar its progress; tortuous corridors and gloomy gulfs were fixed in these defiles, in which the terrible ministers of divine vengeance held themselves in ambush, prepared to harass the march of souls not yet absolved, and to overwhelm with frightful tortures those against whom sentence had already been pronounced. The tomb, therefore, had its snares and narrow passages, its gaping depths and the mazes of its intersecting and twisting corridors. To complete the resemblance nothing more was required than to paint and chisel upon the walls the figures of those gods, genii, and monsters who peopled the regions below. On one side the pious king may be seen, escorted by Amen-Ra and the other divinities whom he had worshipped during life, advancing to plead his cause before Osiris; on the other, the punishment of the wicked helps to give _éclat_ to the royal apotheosis by the contrasts which it affords.
