The greatest length of this portion, reckoned from the Hyrcanian Sea to the (Eastern) Ocean opposite Imaus, is about 30,000 stadia,
10
the route being along the mountainous tract of Taurus; the breadth is less than 10,000 stadia.
11
We have said before, that
12
from the bay of Issus to the eastern sea along the coast of India is about 40,000 stadia, and to Issus from the western extremities at the pillars 30,000 stadia. The recess of the bay of Issus is little, if at all, more to the east than Amisus; from Amisus to Hyrcania is about 10,000 stadia in a line parallel to that which we have described as drawn from the bay of Issus to India. There remains therefore for the portion now delineated the above-mentioned length towards the east, namely, 30,000 stadia.
13
Again, since the breadth of the longest part of the habitable earth, which has the shape of a chlamys, (or a military cloak,) is about 30,000 stadia, this distance would be near the meridian line drawn through the Hyrcanian and the Persian Seas, for the length of the habitable earth is 70,000 stadia. If therefore from Hyrcania to Artemita
14
in Babylonia are 8000 stadia according to Apollodorus of Artemita, and thence to the mouth of the Persian Sea 8000, and again 8000, or a little short of that number, to the places on the same parallel with the extremities of Aethiopia, there would remain, to complete the breadth as I have described it, of the habitable earth, the number of stadia
15
which I have mentioned, reckoning from the recess of the Hyrcanian Sea to its mouth. This segment of the earth being truncated towards the eastern parts, its figure would resemble a cook’s knife, for the mountainous range being prolonged in a straight line, answers to the edge, while the shape of the coast from the mouth of the Hyrcanian Sea to Tamarus on the other side terminates in a circular truncated line.
