It would, however, be an error to see the birth of Egyptian civilization as a consequence of contact with Mesopotamia. The signs of change accumulating towards the end of the predynastic age are too numerous and the outcome of the change is too emphatically Egyptian in its general character and its particulars to allow us to speak of derivation or dependence. In fact, Mesopotamian influence can be entirely discounted—except in the field of writing—without altering in any essential respect the outcome of the change. We have said elsewhere that there is no necessity to assume Mesopotamian influence in order to explain the development of Pharaonic civilization, but it so happens that we have evidence that such influence was, in fact, exercised. We observe that Egypt, in a period of intensified creativity, became acquainted with the achievements of Mesopotamia; that it was stimulated; and that it adapted to its own rapid development such elements as seemed compatible with its efforts. It mostly transformed what it borrowed and after a time rejected even these modified derivations. It is unfortunate that we cannot yet answer the question where and how contact between Egypt and Mesopotamia was established. We only know the time at which it took place. The signs of Sumerian influence point, one and all, to the Protoliterate period in Mesopotamia, and more especially to the latter half of that period; and they appear in Egypt towards the end of the Gerzean period and during the very beginning of the First Dynasty. This is, of course, an invaluable synchronism, even though it is still impossible to express it in exact dates. It may also have a bearing on the question in which locality contact was established. In Egypt, signs of contact with Sumer almost cease after Narmer’s reign; and since contact with Syria increased rather than diminished during the First Dynasty, it seems unlikely that the Mesopotamian influences reached Egypt from the north. The argument is not conclusive; we have seen that Sumerian culture moved upstream along the Tigris and Euphrates, and that a great temple was built at Brak on the Khabur in North Syria in Protoliterate times. But in Syria we do not find signs that native culture was deeply affected by contact with Sumer. This may be due to the incompleteness of our evidence; or it may be that Syrian culture was so unprogressive that it could not profit from such contact in the way Egypt demonstrably did. But before we accept this view we must consider an alternative.
