from Arabia by unbroken heights, and from the upper region from the south by the junctions of the rivers, Astaboras, Astapus, and Astasobus. On the north the Nile flows all the way to Egypt in that tortuous fashion which I have described." This island virtually coincides with the modern province of Atbar. It is probably to this same region that Diodorus refers in his famous description of the Egyptian gold-mining. Although the passage is one of considerable length, it is of such interest and importance that it is perhaps advisable to give it in full: "On the confines of Egypt, Arabia which marches with it, and Ethiopia is a spot possessed of many great mines of gold, where the gold is got together with much suffering and expense. Since the earth is black and has lodes and veins of quartz of surpassing whiteness, and which excel in brilliancy all those natural objects which are noted for their lustre, those who are in charge of the mining works by the numbers of the labourers prepare the gold.
