It has been divided into many parts with many names, determined by boundaries that circumscribe areas both large and small. But since certain tribes are comprised within the vast width of the mountain, some rather insignificant, but others extremely well known (as, for instance, the Parthians, the Medes, the Armenians, a part of the Cappadocians, the Cilicians, and the Pisidians), those which lie for the most part in its northerly parts must be assigned there,1
and those in its southern parts to the southern,2
while those which are situated in the middle of the mountains should, because of the likeness of their climate, be assigned to the north, for the climate in the middle is cold, whereas that in the south is hot. Further, almost all the rivers that rise in the Taurus flow in contrary directions, that is, some into the northern region and others into the southern (they do so at first, at least, although later some of them bend towards the east or west), and they therefore are naturally helpful in our use of these mountains as boundaries in the two-fold division of Asia—just as the sea inside the Pillars,3
which for the most part is approximately in a straight line with these mountains, has proved convenient in the forming of two continents, Europe and Libya, it being the noteworthy boundary between the two.
