This is a most interesting and important passage, as it brings us face to face with primitive peoples in the very earliest stage of the use of metals. The Nomads do not possess skill enough to work the gold-dust of their river, although evidently aware of its existence. Their neighbours being more favoured by the nature of their gold deposit are able to use the metal in the way in which we may with safety conclude that mankind everywhere first employed it. Accustomed to use ornaments of shells made into rude beads, they had no difficulty in adapting for like use the small lumps of native gold. They readily pierced the soft metal and making the nuggets into beads used them to form their necklets and armlets. But although this people had made some progress in the working of gold, they were incapable of working copper and silver. We shall have to return to this passage hereafter. Let us now hear Diodorus in reference to the same region.
He speaks of it in two separate places in his Collections, first in his Second Book, when giving a brief general statement of Arabia and its natural products, and again in the Third Book, when he is giving a more detailed account of the tribes who dwelt along the shores of the Red Sea or, as he called it, the Arabian Gulf.
