““Certain elements of the early dynastic civilization, which do not appear in that of the earlier pre-dynastic period, resemble well-known elements of the civilization of Babylonia. We may instance the use of the cylinder-seal, which died out in Egypt in the time of the XVIIIth Dynasty, but was always used in Babylonia from the earliest to the latest times. The early Egyptian mace-head is of exactly the same type as the early Babylonian one.””
