[31] HERODOTUS (ii. 95) says that they did so in the marshy parts of Lower Egypt. [32] It is difficult to say what the artist meant by the little oblong mark under these windows. Perhaps it represents an outside balcony by which the window could be reached either for the purposes of inspection or in order to add to the store within. [Illustration: FIG. 25.--Brewing, Beni-Hassan; from Champollion, pl. 398.] [Illustration: FIG. 26.--Granaries, Beni-Hassan; from Wilkinson.] [Illustration: FIG. 27.--Granaries; Sakkarah.] The Egyptians had country houses as well as those in town, but the structural arrangements were the same in both. The dwelling of the peasant did not differ very greatly from that of the town-bred artisan, while the villas of the wealthy were only distinguished from their houses in the richer quarters of Thebes and Memphis by their more abundant provision of shady groves, parks, and artificial lakes. Their paintings prove conclusively that the Egyptians had carried horticulture to a very high pitch; they even put their more precious trees in pots like those in which we place orange-trees.[33] [33] These trees must have been planted in large terra-cotta pots, such as are still used in many places for the same purpose. § 4. _Military Architecture._ The Ancient Egyptians have left us very few works of military architecture, and yet, under their great Theban princes, more than one fortress must have been built outside their own country to preserve their supremacy over neighbouring peoples. In the later periods of the empire fortresses were erected in the Delta and in the upper gorges of the Nile, but, unfortunately such works were always carried out in brick and generally in crude brick. The Egyptian architect had at hand in great abundance the finest materials in the world, except marble, and yet they were used by him exclusively for the tomb and the temple. When it was a question of providing an indestructible dwelling for the dead, and so of perpetuating the efficacy of the funeral prayers and offerings, "eternal stone" was not spared; but when less important purposes had to be fulfilled they were content with clay. Baking bricks was a more rapid process than quarrying and dressing stone, and if the house or fortress in which they were used had comparatively slight durability, it was easy enough to replace it with another.
