Beginning among the non-Semitic Sumero-Akkadian population， it maintained for a long time its uninterrupted development， affected mainly by influences from within， namely， the homogeneous local cults which acted and reacted upon each other.The religious systems of other nations did not greatly affect the development of the early non-Semitic religious system of Babylonia.A time at last came， however， when the influence of the Semitic inhabitants of Babylonia and Assyria was not to be gainsaid， and from that moment， the development of their religion took another turn.In all probably this augmentation of Semitic religious influence was due to the increased numbers of the Semitic population， and at the same period the Sumero-Akkadian language began to give way to the Semitic idiom which they spoke.When at last the Semitic Babylonian language came to be used for official documents， we find that， although the non-Semitic divine names are in the main preserved， a certain number of them have been displaced by the Semitic equivalent names， such as ？ama？ for the sun-god， with Kittu and Mê？aru ("justice and righteousness") his attendants； Nabú ("the teacher" = Nebo) with his consort Ta？mêtu ("the hearer")； Addu， Adad， or Dadu， and Rammanu， Ramimu， or Ragimu = Hadad or Rimmon ("the thunderer")； Bêl and Bêltu (Beltis = "the lord" and "the lady" /par excellence/)， with some others of inferior rank.In place of the chief divinity of each state at the head of each separate pantheon， the tendency was to make Merodach， the god of the capital city Babylon， the head of the pantheon， and he seems to have been universally accepted in Babylonia， like A？？ur in Assyria， about 2000B.C.or earlier.
The uniting of two pantheons.
We thus find two pantheons， the Sumero-Akkadian with its many gods， and the Semitic Babylonian with its comparatively few， united， and forming one apparently homogeneous whole.But the creed had taken a fresh tendency.It was no longer a series of small， and to a certain extent antagonistic， pantheons composed of the chief god， his consort， attendants， children， and servants， but a pantheon of considerable extent， containing all the elements of the primitive but smaller pantheons， with a number of great gods who had raised Merodach to be their king.
In Assyria.
Whilst accepting the religion of Babylonia， Assyria nevertheless kept herself distinct from her southern neighbour by a very simple device， by placing at the head of the pantheon the god A？？ur， who became for her the chief of the gods， and at the same time the emblem of her distinct national aspirations--for Assyria had no intention whatever of casting in her lot with her southern neighbour.Nevertheless， Assyria possessed， along with the language of Babylonia， all the literature of that country--indeed， it is from the libraries of her kings that we obtain the best copies of the Babylonian religious texts， treasured and preserved by her with all the veneration of which her religious mind was capable，--and the religious fervour of the Oriental in most cases leaves that of the European， or at least of the ordinary Briton， far behind.
The later period in Assyria.
Assyria went to her downfall at the end of the seventh century before Christ worshipping her national god A？？ur， whose cult did not cease with the destruction of her national independence.In fact， the city of A？？ur， the centre of that worship， continued to exist for a considerable period； but for the history of the religion of Assyria， as preserved there， we wait for the result of the excavations being carried on by the Germans， should they be fortunate enough to obtain texts belonging to the period following the fall of Nineveh.
In Babylonia.
Babylonia， on the other hand， continued the even tenor of her way.
More successful at the end of her independent political career than her northern rival had been， she retained her faith， and remained the unswerving worshipper of Merodach， the great god of Babylon， to whom her priests attributed yet greater powers， and with whom all the other gods were to all appearance identified.This tendency to monotheism， however， never reached the culminating point--never became absolute--except， naturally， in the minds of those who， dissociating themselves， for philosophical reasons， from the superstitious teaching of the priests of Babylonia， decided for themselves that there was but one God， and worshipped Him.That orthodox Jews at that period may have found， in consequence of this monotheistic tendency， converts， is not by any means improbable--indeed， the names met with during the later period imply that converts to Judaism were made.
The picture presented by the study.
Thus we see， from the various inscriptions， both Babylonian and Assyrian--the former of an extremely early period--the growth and development， with at least one branching off， of one of the most important religious systems of the ancient world.It is not so important for modern religion as the development of the beliefs of the Hebrews， but as the creed of the people from which the Hebrew nation sprang， and from which， therefore， it had its beginnings， both corporeal and spiritual， it is such as no student of modern religious systems can afford to neglect.Its legends， and therefore its teachings， as will be seen in these pages， ultimately permeated the Semitic West， and may in some cases even had penetrated Europe， not only through heathen Greece， but also through the early Christians， who， being so many centuries nearer the time of the Assyro-Babylonians， and also nearer the territory which they anciently occupied， than we are， were far better acquainted than the people of the present day with the legends and ideas which they possessed.
