It is generally agreed that they were closely associated with one of the early outpourings of nomadic peoples from Arabia, a country which is favourable for the production of a larger population than it is able to maintain permanently, especially when its natural resources are restricted by a succession of abnormally dry years. In tracing the Akkadians from Arabia, however, we are confronted at the outset with the difficulty that its prehistoric, and many of its present-day, inhabitants are not of the characteristic Semitic type. On the Ancient Egyptian pottery and monuments the Arabs are depicted as men who closely resembled the representatives of the Mediterranean race in the Nile valley and elsewhere. They shaved neither scalps nor faces as did the historic Sumerians and Egyptians, but grew the slight moustache and chin-tuft beard like the Libyans on the north and the majority of the men whose bodies have been preserved in pre-Dynastic graves in the Nile valley. “If”, writes Professor Elliot Smith, “the generally accepted view is true, that Arabia was the original home of the Semites, the Arab must have undergone a profound change in his physical characters after he left his homeland and before he reached Babylonia.” This authority is of opinion that the Arabians first migrated into Palestine and northern Syria, where they mingled with the southward-migrating Armenoid peoples from Asia Minor. “This blend of Arabs,
