Sumerian, however, was not the only language in the neighbourhood of the Babylonian plain which was agglutinative. Further to the east, in the highlands of Elam, other agglutinative languages were spoken, monuments of one or more of which have been preserved to us. Whether or not the agglutinative languages of Elam were related to the Sumerian of Babylonia, I cannot tell; so far as our materials go at present they do not warrant us in saying more than that, like Sumerian, they were of the agglutinative type. It is only rarely that the scientific philologist is able to separate some of the multitudinous languages of the globe into genealogically related groups; for the most part they stand isolated and apart from one another, and, however much we may wish to group them together, it is seldom that we find such proofs of a common descent as will satisfy the requirements of science. Families of speech—or at all events such as can be scientifically proved to be so—are the exception and not the rule.

Eastward of Sumer the type of language was thus agglutinative, as it was in Sumer itself. And in the days when civilization first grew up there, there is no sign or trace of the languages we call inflectional. The speakers of Aryan dialects, whom we find in classical times in Media or Persia or North-Western India, belong to a later epoch; the old belief in the Asiatic cradle of the Aryan tongues has long since been given up by the anthropologist and comparative philologist,[67] and it is recognized that if we are to look for it anywhere it must be in Eastern Europe. The Semitic languages are equally absent; the tide of Semitic speech which eventually overflowed Babylonia, surged northward and eastward into Assyria and Elam, but never succeeded in passing Susiana, and was finally driven again from the ground it had once gained there. The home of the Semite lay to the west and not to the east of the Babylonian plain. Babylonian culture owed its origin to a race whose type of language was that of the Finn, of the Magyar or the Japanese.

The physical characteristics of this race cannot as yet be fully determined. The oldest sculptures yielded by Babylonian excavation belong to a time when the Semite was already in the land. It might be supposed that the early monuments of Tello, which were erected by Sumerian princes and go back to Sumerian times, would give us the necessary materials; but not only are they too rude and infantile to be of scientific use, they also indicate the existence of two ethnological types, one heavily bearded, the other beardless, with oblique eyes and negrito-like face. It is not until we come to the age of Semitic domination that sculpture is sufficiently realistic for exact anthropological purposes. At the same time, there was to the last a marked contrast of both form and feature in the artistic representation of the Babylonian and his more purely Semitic Assyrian neighbour. The squat, thick figure, the full, well-shaven cheeks, the large, almond-shaped eyes and round head of King Merodach-nadin-akhi in the twelfth century B.C. still reproduce the characteristic form and features of the statues found in the palace of Gudea, the Sumerian high-priest of Lagas, who lived more than a thousand years before. The aquiline or hooked nose, the thick lips and muscular limbs which distinguished the Assyrian are generally wanting in Babylonia. And, on the other hand, there is a likeness between the Babylonian as he is portrayed on the monuments and the Elamite adversaries of Assur-bani-pal, some of whom, it is noticeable, are depicted with beards, though the excavations of Dieulafoy and de Morgan at Susa have shown (according to Quatrefages and Hamy) that a beardless and short-nosed negrito type with round heads was aboriginal in Elam. The same type is reproduced in one of the heads found at Tello, and M. de Morgan has pointed out that similar brachycephalic and beardless negritos are represented on the monuments of Naram-Sin as serving in the army of Akkad.[68] We may conclude, therefore, that they still formed a part of the population of Northern Babylonia even in the age when it had passed completely under Semitic rule. Indeed, Dr. Pinches has shown that the pure Semitic type is not depicted in Babylonian art, outside the kingdom of Akkad, “before the time of the First dynasty of Babylon, which began to reign about B.C. 2300.”

It has often been maintained that the Sumerians themselves were an immigrant people, who had descended from the mountains of Elam. There is nothing unreasonable in the supposition; it was always difficult to prevent the mountaineers of Elam from making raids in Babylonia, and one of their tribes succeeded in settling in the country and establishing at Babylon one of the longest-lived of its dynasties. But the supposition mainly rests upon two facts. The pictorial hieroglyphs out of which the cuneiform characters have developed had no special sign for “river,” while the same character represented both “mountain” and “country.” It would seem, therefore, that the land in which the cuneiform system of writing was first invented was just the converse of the Babylonian plain, being at once mountainous and riverless. That the same character means both “mountain” and “country” is no doubt a strong argument in favour of the Elamite origin of Babylonian civilization. That the use of the primitive hieroglyphs should have survived in Elam while it was lost in Babylonia, as M. de Morgan’s discoveries have shown to be the case, is also another fact which may perhaps be claimed on the same side; at any rate it indicates that they were known to the Elamites before the cursive cuneiform had developed out of them. But the want of a special character for “river” is not so decisive as it appears at first sight to be. The word “river” is represented by two ideographic signs which literally signify “the watery deep,” and so point to the fact that those who originally invented them lived not in the highlands of the East, but on the shores of that Persian Gulf which the Babylonians of the historic period still called “the deep.” As it was also known as “the salt river,” it is not difficult to understand how, to those whose experience of navigable water had been confined to the Persian Gulf, the Tigris and Euphrates would have seemed but repetitions of the Gulf on a smaller scale.[69]

The rise of Sumerian culture on the shores of the Persian Gulf is in accordance with Babylonian tradition. Babylonian myths told how Oannes or Ea, the god of culture, had risen each morning out of his palace in “the deep,” bringing with him the elements of civilization which he communicated to mankind. Letters, science and art had all been his gifts. He had instructed the wild tribes of the coast to build houses and erect temples; he had compiled for them the first law-book, and had instructed them in the mysteries of agriculture. Babylonian civilization was sea-born. The system of cosmology which finally won its way to acceptance with the priesthood and philosophers of Babylonia was one which had been first conceived at Eridu, the site of which is now more than a hundred miles distant from the sea, but in the early days of Babylonian history, before the silting up of the shore, had been its seaport. Here the first man Adam[70] was supposed to have lived, and to have spent his time fishing in the waters of the Gulf. The whole earth was believed to have grown out of a primeval deep like the mud-flats which the inhabitants of Eridu saw slowly emerging from the retreating sea. Philosophy and cosmology, with the theology with which they were associated, looked back upon Eridu and the Babylonian coast as their primeval home.[71]

In fact the physical conditions of the Babylonian plain rendered it impossible for the first culture of the country to have sprung up in it. Before it was reclaimed by engineering skill and labour the larger part of it had been a pestiferous marsh. The science needed for making it habitable, at least by civilized man, must have arisen outside its boundaries. Only when he was already armed with a civilization which enabled him to dig canals, to mould bricks, and pile his houses and temples on artificial foundations could the Sumerian have settled in the Babylonian plain and there developed it still further. The cities of the plain grew up each round its sanctuary, which became a centre of civilization and progress, of agriculture and trade. But the builders of the sanctuaries must have brought their culture with them from elsewhere.

Of these sanctuaries the most venerable was that of Bel the Elder at Nippur. It has been systematically excavated by the Americans down to its foundations, and the successive strata of its history laid bare. Inscribed objects have been found in all the strata, carrying the history of the cuneiform system of writing back to the days when the temple was originally built. But it is still the cuneiform system of writing as far back as we can go, that is to say the characters are the cursive forms of earlier hieroglyphic pictures, the features of which are in most cases scarcely traceable. Here and there, it is true, the primitive pictorial form has been preserved, but this is the exception and not the rule. As a rule the earliest writing found at Nippur, and coeval with the foundation of its temple, is already the degenerated and cursive hand which we call cuneiform.

The fact is very noteworthy. The cuneiform characters have assumed the shapes which give them their name owing to their having been inscribed on clay by a stylus of wood or metal, which obliged the writer to substitute a series of wedge-like indentations for curves and straight lines. As time went on, the number of the wedges was reduced, the forms of the characters were simplified, and the resemblance to the pictures they were once intended to represent became more and more indistinct. The cuneiform script is, in short, a running hand, like the hieratic of Egypt. But whereas in Egypt the hieratic running hand does not come into common use until long after the beginning of the monumental period, while the pictorial hieroglyphs continued to be employed to the last, in Babylonia the cuneiform running hand has superseded the primeval pictures as far back as our records carry us. When the temple of Nippur was built—and it was probably one of the first, if not the first, to be built in the Babylonian plain—the clay tablet was already in use for writing purposes, and the cursive cuneiform had taken the place of the older hieroglyphs.

The Babylonian plain was called by its Sumerian inhabitants the Edin, or “Plain,” a name which was borrowed by the Semites and has been made familiar to us by the book of Genesis. Originally it had meant all the uncultivated flats on either side of the Euphrates, but it soon acquired the sense of the country as opposed to the city, and so of the cultivated plain itself. Most of the important Babylonian cities were built in it between the Euphrates on the west and the Tigris on the east. A few only lay beyond it on the western bank of the Euphrates. One of these was Eridu, another was Ur, a third was Borsippa.
