Berbers are undoubtedly the descendants of the races known to the Greeks and Romans under the generic name of Libyans. The Kabyles of the hills between Algiers and Bougie, and the Shawia of the Aures Mountains are very similar to one another and may be taken as typical Berbers. They are distinctly white-skinned, even when sunburned. Usually they have black hair and brown or hazel eyes, some have yellow hair and blue eyes. In the royal necropolis of Thebes of about 1300 B.C., certain Libyans are depicted as having a white skin, blue eyes and fair beards. Blonds are represented on Egyptian monuments from 1700 B.C. and were noted by the Greeks in the fourth century B.C. In the east the blonds have quite died out, but there are patches of this race in the west of North Africa. This fair race still remain an unsolved problem. Some students bring them from Spain, other authors from Italy, others again from the east. Perhaps they were a sporadic invasions and formed an aristocratic class. One suggestion is that they were Proto-Nordics who formed a part of the various groups of Asiatics who raided Egypt about 1300 B.C. and moved westwards.
