The ruins of Susa are now surrounded by a wilderness, inhabited only by lions and hyænas. The soil is still productive of grass, and the remains of numerous canals attest the ancient cultivation. Steep mounds of débris and heaps of ruins rise thickly on the left bank of the Shapur, in appearance closely resembling the remains of Babylon and Nineveh. The highest mound is nearest the river; it rises 120 feet above the level of the water, is 3000 feet in circumference, and appears to have supported a part of the citadel; the mound abutting on the north only rises 80 or 90 feet, and forms a square, the sides of which measure 1000 or 1200 feet. On this the remains of a large building have been discovered. Further to the east is an extensive platform, the circumference of which far surpasses that of the two first put together; the height on the south side reaches 70 feet and on the east and north about 50 feet. On the east of these three heaps are mounds of a smaller size. These may be remains of the city, while the others represent the citadel. The entire circuit of the ruins is about 7-1/2 miles. They confirm the statement of Strabo that Susa was built of brick, inasmuch as they present masses of bricks, partly burnt, partly dried in the sun. But even the palaces in the citadels were built of bricks in the outer walls only; they did not contain those narrow long porticoes, which formed the royal palaces of Nineveh, but were rather large square halls, resting on huge terraces. The bases and remains of the northern hill allow us to trace three magnificent porticoes. The interior of the building was formed by a large hall with pillars, the roof of which was supported by 36 pillars ranged in six rows; the pillars were of stone, slight and tall, the capitals were formed by the fore-quarters of kneeling horses. Round three sides of this hall, the north, east, and west, were placed porticoes, 50 feet in breadth, the roofs of which were supported by 12 pillars in two rows. Four pillars of the chief hall bear the same inscription in cuneiform letters, and, as always, in the Persian, Babylonian, and Turanian languages. In this Artaxerxes Mnemon (405-359 B.C.) relates that his great-great-grandfather (_apanyaka_) Darius had erected this building and that he had restored it. He entreats Auramazda, Anahita, and Mithra, to protect him and his work. On some pillars we find the inscription: "I, Artaxerxes, the great king, the king of kings, son of the king Darius" (_i.e._ Darius Ochus).[440]
