Neither indeed has he stated that Thapsacus and Babylon are on the same meridian.
From there they travel by caravan to Mesopotamia,passing through Thapsacus and Larissa.
And between these two parallels the line from Thapsacus to Egypt is drawn somewhat diagonally and obliquely.
From this it follows, says Hipparchus,that the Caspian Gates are equidistant from Thapsacus and from Mt.
Eratosthenes has stated, indeed,that the distance from Thapsacus to Babylon is four thousand eight hundred stadia;
Caspius and Thapsacus are virtually situated on the same meridian could not be based on the authority of Eratosthenes, but on that of Hipparchus himself.
Caspius to the Caspian Gates is equal in length to the line from Thapsacus to the same point?
On the assumptions of Hipparchus, Eratosthenes' Thapsacus is made to lie at a latitude 7,300 stadia north of Pelusiumsee figure.
On the contrary, Hipparchus himself pointed out that, according to Eratosthenes,Babylon is more than two thousand stadia farther east than Thapsacus.
Of this triangle he makes the line from Thapsacus to Babylon the hypotenuse, which he says is four thousand eight hundred stadia;
At this point, p313 then, in addition to making further use of his now demolished assumptions for the construction of his right-angled triangle, he also assumes this point that is not granted, namely,that the hypotenuse- the straight line from Thapsacus to Babylon- is within four thousand eight hundred stadia.
And, thirdly, Eratosthenes has nowhere declared that Thapsacus lies north of Babylon more than four thousand five hundred stadia.
For from the passage at Thapsacus, he says, along the Euphrates to Babylon, it is four thousand eight hundred stadia, and thence to the outlet of the Euphrates and the city of Teredon, three thousand;
Now because Eratosthenes could not speak of the route along the mountain-range as measured,he spoke of only the route from Thapsacus to the Caspian Gates as measured, and he added the words"roughly speaking";
But as regards the distances from Thapsacus northward, the stadia have been measured up to the Armenian Gates and amount to about one thousand one hundred;
Indeed, the line through Babylon, 63 if further produced as far as the straight meridian through Thapsacus, would, to the eye, be equal- or at all events approximately equal- to the line from the Caspian Gates to Thapsacus;
And besides, as regards the stretch from Thapsacus to Armenia- Eratosthenes does not even know, as a distance that has been wholly measured, the western side that is marked off by the Euphrates; nay, he says he does not know how great is the stretch next to Armenia and the northern mountains, from the fact that it is unmeasured.
Now whether he places these two lengths on a straight line with each other, oras though they formed an angle at Thapsacus, it is at any rate clear from his own words that he does not make either line parallel to the length of the inhabited world.
It is true that Eratosthenes has stated the route to Babylon from Thapsacus to be four thousand eight hundred stadia long, though he added, as on purpose,"following the course of the Euphrates," in order that no one might interpret it as a straight line or as a measure of the distance between two parallels.
And the perpendicular from Babylon to the meridian line through Thapsacus, slightly more than a thousand stadia- p311 the amount by which the line to Thapsacus65 exceeded the line up to Babylon;
And besides, I have already stated that,if we grant that two lines are drawn from the Caspian Gates, one to Thapsacus, the other to that part of the Armenian Mountains that corresponds in position to Thapsacus(which, according to Hipparchus himself, is distant from Thapsacus at the least two thousand one hundred stadia), it is impossible for both these lines to be parallel either to each other or to the line through Babylon, which Eratosthenes called"southern side.".
He is correct in censuring Eratosthenes for this, namely,for calling the line from Thapsacus to Egypt the length of this section- which is as if one should call the diagonal of a parallelogram its length.
Secondly, Eratosthenes does not say that the distance from Thapsacus to the mountains is two thousand one hundred stadia, 78but that there is a remainder of that distance which has not been measured;
And hence Babylon would come to be farther east than Thapsacus by as much as the line from the Caspian Gates to Thapsacus exceeds the line from the Carmanian frontiers to Babylon!
And by drawing a rectangle whose sides are formed by meridians through Thapsacus and the Caspian Gates, respectively, and by parallels of latitude through Thapsacus and the Caspian Gates, and though Babylon, he easily convicts Eratosthenes of inconsistency.
Hipparchus is also wrong in his next effort,in which he wishes to draw the inference that Eratosthenes gives the highway from Thapsacus to the Caspian Gates- a highway the length of which Eratosthenes has estimated at ten thousand stadia- as measured in a straight line, although it was not so measured, the straight line being much shorter.
