include the kingdoms of Semiramis and Ninus, who are both of them known as Syrian monarchs; the first built Babylon, which he made his royal residence; the second Ninus,[582] the capital of Syria;[583] and the same dialect still exists on both sides of the Euphrates. The idea of thus dismembering so renowned a nation, and allotting its portions to strange nations with which it had no connexion, is as peculiarly unfortunate. Eratosthenes cannot plead that he was compelled to do this on account of its size, for had it extended as far as the sea and the frontiers of Arabia Felix and Egypt, even then it would not have been as large as India, or even Ariana. It would have therefore been much better to have enlarged the third section, making it comprehend the whole space as far as the Sea of Syria; but if this were done, the southern side would not be as he represents it, nor yet in a straight line, but starting from Carmania would follow the right side of the sea-shore from the Persian Gulf to the mouth of the Euphrates; it would then approach the limits of Mesene[584] and Babylon, where the Isthmus commences which separates Arabia Felix from the rest of the continent. Traversing the Isthmus, it would continue its course to the recess of the Arabian Gulf and Pelusium,[585] thence to the mouth of the Nile at Canopus.[586] Such would be the southern side. The west would be traced by the sea-shore from the [river’s] mouth at Canopus to Cilicia.[587] 32. The fourth section would consist of Arabia Felix, the Arabian Gulf, and the whole of Egypt and Ethiopia. Its length bounded by two meridians, one drawn through its most western point, the other through its most eastern; and its breadth by two parallels through its most northern and southern points. For this is the best way to describe the extent of irregular figures, whose length and breadth cannot be determined by their sides. In general it is to be observed, that length and breadth are to be understood in different ways, according as you speak of the whole or a part. Of a whole, the greater distance is called its length, and the lesser its breadth; of a part, that is to be considered the length which is parallel to the length of the whole, without any regard whether it, or that which is left for the breadth, be the greater distance. The length of the whole habitable earth is measured from east to west by a line drawn parallel to the equator, and its breadth from north to south in the direction of the meridian; consequently, the length of any of the parts ought to be portions of a line drawn parallel to the length of the whole, and their breadth to the breadth of the whole. For, in the first place, by this means the size of the whole habitable earth will be best described; and secondly, the disposition and configuration of its parts, and the manner in which one may be said to be greater or less than another, will be made manifest by thus comparing them.
