25. To refute Crates would require a lengthened argument, which here perhaps may be considered out of place. Aristarchus we commend for rejecting the hypothesis of Crates, which is open to many objections, and for referring the expression of the poet to our Ethiopia. But the remainder of his statement we must discuss. First, his minute examination of the reading is altogether fruitless, for whichever way it may have been written, his interpretation is equally applicable to both; for what difference is there whether you say thus—In our opinion there are two Ethiopias, one towards the east, the other to the west; or thus—For they are as well towards the east as the west? Secondly, he makes false assumptions. For admitting that the poet was ignorant of the isthmus,[185] and that he alludes to the Ethiopia contiguous to Egypt, when he says, The Ethiopians separated into two divisions;[186] what then? Are they not separated into two divisions, and could the poet have thus expressed himself if he had been in ignorance? Is not Egypt, nay, are not the Egyptians, separated into two divisions by the Nile from the Delta to Syene,[187] These towards the west, those towards the east? And what else is Egypt, with the exception of the island formed by the river and overflowed by its waters; does it not lie on either side of the river both east and west? Ethiopia runs in the same direction as Egypt, and resembles it both in its position with respect to the Nile, and in its other geographical circumstances. It is narrow, long, and subject to inundation; beyond the reach of this inundation it is desolate and parched, and unfitted for the habitation of man; some districts lying to the east and some to the west of [the river]. How then can we deny that it is separated into two divisions? Shall the Nile, which is looked upon by some people as the proper boundary line between Asia and Libya,[188] and which extends southward in length more than 10,000 stadia, embracing in its breadth islands which contain populations of above ten thousand men, the largest of these being Meroe, the seat of empire and metropolis of the Ethiopians, be regarded as too insignificant to divide Ethiopia into two parts? The greatest obstacle which they who object to the river being made the line of demarcation between the two continents are able to allege, is, that Egypt and Ethiopia are by this means divided, one part of each being assigned to Libya, and the other to Asia, or, if this will not suit, the continents cannot be divided at all, or at least not by the river.
