From this brief survey of events it will have been noted that Babylon's supremacy falls in the middle period of her country's history, during which she distributed a civilization in the origin of which she played no part. When she passed, the culture she had handed on passed with her, though on Mesopotamian soil its decay was gradual. But she had already delivered her message, and it has left its mark on the remains of other races of antiquity which have come down to us. We shall see that it was in three main periods that her influence made itself felt in any marked degree beyond the limits of the home-land. The earliest of these periods of external contact was that of her First Dynasty of West-Semitic rulers, though the most striking evidence of its effect is only forthcoming after some centuries had passed. In the second period the process was indirect, her culture being carried north and west by the expansion of Assyria. The last of the three epochs coincides with the rule of the Neo-Babylonian kings, when, thanks to her natural resources, the country not only regained her independence, but for a short time established an empire which far eclipsed her earlier effort. And in spite of her speedy return, under Persian rule, to the position of a subject province, her foreign influence may be regarded as operative, it is true in diminishing intensity, well into the Hellenic period. The concluding chapter will deal in some detail with certain features of Babylonian civilization, and with the extent to which it may have moulded the cultural development of other races. In the latter connexion a series of claims has been put forward which cannot be ignored in any treatment of the nation's history. Some of the most interesting contributions that have recently been made to Assyriologieal study undoubtedly concern the influence of ideas, which earlier research had already shown to be of Babylonian origin. Within recent years a school has arisen in Germany which emphasizes the part played by Babylon in the religious development of Western Asia, and, in a minor degree, of Europe. The evidence on which reliance has been placed to prove the spread of Babylonian thought throughout the ancient world has been furnished mainly by Israel and Greece; and it is claimed that many features both in Hebrew religion and in Greek mythology can only be rightly studied in the light thrown upon them by Babylonian parallels from which they were ultimately derived. It will therefore be necessary to examine briefly the theory which underlies most recent speculation on this subject, and to ascertain, if possible, how far it may be relied on to furnish results of permanent value.
