That they were brave and warlike, ingenious, energetic, and persevering, we have ample evidence, which will appear in later chapters of this work; but we can do little more than conjecture their physical appearance, which, however, we may fairly suppose to have resembled that of other Ethiopian nations.
When the early inhabitants of ChaldAea are pronounced to have belonged to the same race with the dwellers upon the Upper Nile, the question naturally arises, which were the primitive people, and which the colonists?
Is the country at the head of the Persian Gulf to be regarded as the original abode of the Cushite race, whence it spread eastward and westward, on the one hand to Susiana, Persia Proper, Carmania, Gedrosia, and India itself; on the other to Arabia and the east coast of Africa?
Or are we to suppose that the migration proceeded in one direction only--that the Cushites, having occupied the country immediately to the south of Egypt, sent their colonies along the south coast of Arabia, whence they crept on into the Persian Gulf, occupying Chaldaea and Susiana, and thence spreading into Mekran, Kerman, and the regions bordering upon the Indus?
Plausible reasons maybe adduced in support of either hypothesis.

The situation of Babylonia, and its proximity to that mountain region where man must have first "increased and multiplied" after the Flood, are in favor of its being the original centre from which the other Cushite races were derived.

The Biblical genealogy of the sons of Ham points, however, the other way; for it derives Nimrod from Cush, not Cush from Nimrod.

Indeed this document seems to follow the Hamites from Africa--emphatically "the land of Ham"-- in one line along Southern Arabia to Shinar or Babylonia, in another from Egypt through Canaan into Syria.

The antiquity of civilization in the valley of the Nile, which preceded by many centuries that even of primitive Chaldaea, is another argument in favor of the migration having been from west to east; and the monuments and traditions of the Chaldaeans themselves have been thought to present some curious indications of an East African origin.
