Besides these lakes, there were contained within the limits of the Empire a number of petty tarns, which do not merit particular description. Such were the Bahr-el-Taka, and other small lakes on the right bank of the middle Orontes, the Birket-el-Limum in the Lebanon, and the Birket-er-Eam on the southern flank of Hermon. It is unnecessary, however, to pursue this subject any further. But a few words must be added on the chief cities of the Empire, before this chapter is brought to a conclusion. The cities of the Empire may be divided into those of the dominant country and those of the provinces. Those of the dominant country were, for the most part, identical with the towns already described as belonging to the ancient Chaldaea, Besides Babylon itself, there flourished in the Babylonian period the cities of Borsippa, Duraba, Sippara or Sepharvaim, Opis, Psittace, Cutha, Orchoe or Erech, and Diridotis or Teredon. The sites of most of those have been described in the first volume; but it remains to state briefly the positions of some few which were either new creations or comparatively undistinguished in the earlier times. Opis, a town of sufficient magnitude to attract the attention of Herodotus, was situated on the left or east bank of the Tigris, near the point where the Diyaleh or Gyndes joined the main river. Its position was south of the Gyndes embouchure, and it might be reckoned as lying upon either river. The true name of the place--that which it bears in the cuneiform inscriptions--was Hupiya; and its site is probably marked by the ruins at Khafaji, near Baghdad, which place is thought to retain, in a corrupted form, the original appellation. Psittace or Sitace, the town which gave name to the province of Sittacene, was in the near neighborhood of Opis, lying on the same side of the Tigris, but lower down, at least as low as the modern fort of the Zobeid chief. Its exact site has not been as yet discovered. Teredon, or Diriaotis, appears to have been first founded by Nebuchadnezzar. It lay on the coast of the Persian Gulf, a little west of the mouth of the Euphrates, and protected by a quay, or a breakwater, from the high tides that rolled in from the Indian Ocean. There is great difficulty in identifying its site, owing to the extreme uncertainty as to the exact position of the coast-line, and the course of the river, in the time of Nebuchadnezzar. Probably it should be sought about Zobair, or a little further inland.. The chief provincial cities were Susa and Badaca in Susiana; Anat, Sirki, and Carchemish, on the Middle Euphrates; Sidikan on the Khabour; Harran on the Bilik; Hamath, Damascus, and Jerusalem, in Inner Syria; Tyre, Sidon, Ashdod, Ascalon, and Gaza, upon the coast. Of these, Susa was undoubtedly the most important; indeed, it deserves to be regarded as the second city of the Empire.
