So far back as we have yet been able to penetrate, we find in the southern part of Mesopotamia a number of petty independent kingdoms, governed from their capital cities. Our present knowledge of this land and its inhabitants may be briefly summed up.
After the river Euphrates, with countless windings and sharp falls, has cleft the Syrio-Mesopotamian plain where it fertilises the districts contiguous on its banks, it approaches to within a few miles of the Tigris, and both streams water a completely flat plain, intersected by numerous rivers and canals, and, for the most part, flooded by the Euphrates in the summer.
The numerous districts on both sides of the lower Tigris and west of the Euphrates which are out of reach of the irrigation have a desert character, as rain is as rare here as in Egypt. But the irrigated land was proportionately fertile; at least it was so in antiquity and the Middle Ages. The district at the mouth of the streams was of a marshy character with numerous swamps and lakes. In olden times the confluence of both rivers, at latitude about 31° N., formed a long narrow bay which has now been filled up by their deposits. The Arabian Desert lies at the west of the Euphrates, or rather on its western arm, the Pallakopas. The country on the east of the Tigris rises gradually to the wild mountainous boundary of the Iranian highlands, which descends in terrace form to the Tigris, to which it sends numerous rivers, which in earlier times flowed direct into the sea.
At the present time the greater part of this district is a swampy desert traversed only by wandering tribes, whilst in antiquity, and again at the time of the Caliphs, it was made one of the most fertile countries in the world by dint of careful irrigation, regulation, and the construction of dams and canals.[18]
The most ancient population of this country formed several closely related races which had no connection with the other nations of Western Asia, but in the course of historical evolution they lost their language and nationality and were submerged in the neighbouring races.
In the land of Makan, the district of the mouth of the two chief rivers, were the Sumerians (Sumer, with its chief city of Ur, on the Euphrates); and in the northern part of the river country (Melucha land) from Erech, now Warka, upwards to the borders of the Mesopotamian steppes, lived the Accadians, so called from Agade, their capital, north of Babylon. To the east of the Tigris, far into the pathless districts of the Zagros Mountains, dwelt the warlike races of the Kossæans (Assyrian Kasshu). From their home, mode of life and character, they were evidently the predecessors of the modern Kurds, who belong, by language, to the Iranians. Next came the land of Elam, or Anshan, as it was called in the language of the country, the district of the rivers Choaspes and Eulæos, called by the Greeks Kissian, with the capital Shushan, the Susa of the Greeks.
Whilst the Kossæans were always a wild mountainous people, and the inhabitants of the plains of Elam, although they had a firmly established state organization, were dependent on their western neighbours for culture, Sumer and Accad (i.e. Babylonia) possessed an ancient and a complete, independently evolved culture, which, although second to that of the Lower Nile in innate worth and exclusive evolution, perhaps exceeded it in historical influence. The surplus of water from inundations was distributed over the country by means of canals and dykes. Thus ensued a better-ordered life of the state from the closer union of the different provinces. The temples of the great gods formed the centres of the different districts from which, as with the Egyptians, the cities of Babylonia arose first everywhere.
In Ur (now El-Mugheir) there was a temple of the moon-god Sin (or Nannar). In Eridu (now Abu Shahrein) was the temple of Ea, the ancient god of the ocean, and in Larsa (now Senkereh) that of the sun-god Babbar (or Shamash), the lord of the city. The latter was worshipped in like manner in Sippar (now Abu Habba), whilst in the neighbouring Agade (Accad) the goddess Anunit was the deity of the city. On the south lay the sacred “Gate of the Gods” Ka-Dingira, the Semitic Babel (Babylon), the capital of the country. [With it was later united the city of Borsippa.] The city Erech (Orchoë, now Warka), the sanctuary of the goddess Nana (Ishtar), was held in special veneration. North of Larsa was Girsu; on the canal Shatt-el-Khai was probably Lagash (now Telloh); north of this the city of Isin; near it was for a time the chief city of all Babylonia, Nippur, which was the home of the god Bel. It is here that the excavations of the University of Pennsylvania have been so fruitful. About fifteen miles northeast of Babylon was Kutha (now Tel-Ibrahim), whose god was Nergal; near Kutha was Kish. In the northern limit of Babylonia were Dur-Kurigalzu, nearly opposite the present Baghdad; and Upi [or Opis.]
It seems therefore that the lay dynasty arose mainly from the priesthood of these temples, for the kings are universally found in closest relation to the city deities, in whose honour they built or restored the temples, and down to their last day the priestly dignity ranked foremost in the title of the Babylonian kings.[c]
