The defective side of Chaldæan architecture, therefore, consists in the lack of stone supports rising proudly into space like the Egyptian column, and upholding on their bold heads, quite as well as the thickest walls, the foot of the arch, the architraves, the roof, the upper terraces or the upper stories of the building. But the proof that the architects would have hewn columns of stone, if nature had furnished them with the necessary material, is just this ingenious artifice by which they succeeded in replacing them; and moreover they did not hesitate to employ small columns of wood or metal in the construction of small buildings, such as the shrines of their gods. A stela of King Nabu-ablu-iddin (about B.C. 900), found at Abu Habbah, represents the shrine of the god Samas, supported by small wooden pillars, covered with plates of bronze overlapping each other so as to resemble the trunk of a palm tree (see fig. 29). The base and the capital are alike; they are composed of a double volute shaped like a lotus-flower, approaching somewhat the Ionic capital; in short, the Chaldæans knew how to make use of the column in minor architecture. One doorway at least was opened in each façade of the palace of Tello, but these openings were not on the axis of the structure, nor even symmetrical. The principal side (the north-east) had two entrances; the largest, nearly in the middle of the swell, had an opening 3 ft. 11 in. broad. It was constructed at a later period--that is to say, at the time near the Christian era when the Græco-Parthian kings of Characene conceived the idea of restoring Tello and installing themselves there. Like the Arab houses of our day, the outer walls of the palace of Gudea show no other openings; there are neither windows nor lights of any sort, admitting the air and the day, and looking out over the country or the town.
