On one side of the Temple Court there were several chambers called Priests' Rooms, but the temple itself and the portions of the palace connected with it are not as well preserved as the other parts, and have nothing about them to interest us in their study. The palaces of Nineveh are much less perfect than the palace-temples of Thebes, and cannot be described with as much exactness. There is no wall of them still standing more than sixteen feet above the ground, and we do not even know whether they had upper stories or not, or how they were lighted--in a word, nothing is positively known about them above the ground floors, and it is very strange that the sculptures nowhere represent a royal residence. But what we do know of the Assyrians proves that they equalled and perhaps excelled all other Oriental nations as architects and designers, as well as in other departments of art and industry. [Illustration: FIG. 21.--RESTORATION OF AN ASSYRIAN PALACE.] This representation of an Assyrian palace (Fig. 21) is a restoration, as it is called, being made up by a careful study of the remains and such facts as can be learned from bas-reliefs, and cannot be wholly unlike the dwellings of the king-gods. It is pleasing in general appearance, and for lightness and elegance is even to be preferred to Egyptian architecture, though it is far inferior in dignity and impressiveness. The Assyrians knew the use of both column and arch, but never developed either to any extent. They also employed the obelisk, and it is noticeable that instead of terminating it with a pyramid, as was the case in Egypt, they capped it with the diminishing terraces, which is the fundamental form which underlies all the architecture of the country, as the smooth pyramid is the most prominent element in the architecture of Egypt. BABYLON. It is probable that Babylon was the largest and finest of all the ancient cities. The walls which surrounded it, together with its hanging gardens, were reckoned among the "seven wonders of the world" by the ancients. Its walls were pierced by a hundred gates and surmounted by two hundred and fifty towers; these towers added much to the grand appearance of the city; they were not very high above the walls, and were probably used as guard-rooms by soldiers. The River Euphrates ran through the city. Brick walls were built upon its banks, and every street which led to the river had a gateway in these walls which opened to a sloping landing which extended down to the water's edge; boats were kept at these landings for those who wished to cross the stream. There was also a foot-bridge across the river that could be used only by day, and one writer, Diodorus, declares that a tunnel also existed which joined the two sides of the river, and was fifteen feet wide and twelve feet high in the inside.
