The lower parts of the country on each side Meroë, along the Nile towards the Red Sea, are occupied by Megabari and Blemmyes, who are subject to the Ethiopians, and border upon the Egyptians; about the sea are Troglodytæ. The Troglodytæ, in the latitude of Meroë, are distant ten or twelve days’ journey from the Nile. On the left of the course of the Nile live Nubæ in Libya, a populous nation. They begin [CAS. 787] from Meroë, and extend as far as the bends (of the river). They are not subject to the Ethiopians, but live independently, being distributed into several sovereignties. The extent of Egypt along the sea, from the Pelusiac to the Canobic mouth, is 1300 stadia. Such is the account of Eratosthenes. 3. We must, however, enter into a further detail of particulars. And first, we must speak of the parts about Egypt, proceeding from those that are better known to those which follow next in order. The Nile produces some common effects in this and the contiguous tract of country, namely, that of the Ethiopians above it, in watering them at the time of its rise, and leaving those parts only habitable which have been covered by the inundation; it intersects the higher lands, and all the tract elevated above its current on both sides, which however are uninhabited and a desert, from an absolute want of water. But the Nile does not traverse the whole of Ethiopia, nor alone, nor in a straight line, nor a country which is well inhabited. But Egypt it traverses both alone and entirely, and in a straight line, from the lesser cataract above Syene and Elephantina, (which are the boundaries of Egypt and Ethiopia,) to the mouths by which it discharges itself into the sea. The Ethiopians at present lead for the most part a wandering life, and are destitute of the means of subsistence, on account of the barrenness of the soil, the disadvantages of climate, and their great distance from us. Now the contrary is the case with the Egyptians in all these respects. For they have lived from the first under a regular form of government, they were a people of civilized manners, and were settled in a well-known country; their institutions have been recorded and mentioned in terms of praise, for they seemed to have availed themselves of the fertility of their country in the best possible manner by the partition of it (and by the classification of persons) which they adopted, and by their general care. When they had appointed a king, they divided the people into three classes, into soldiers, husbandmen, and priests. The latter had the care of everything relating to sacred things (of the gods), the others of what related to man; some had the management of warlike affairs, others attended to the concerns of peace, the cultivation of the ground, and the practice of the arts, from which the king derived his revenue. The priests devoted themselves to the study of philosophy and astronomy, and were companions of the kings.
