By what guess- work he arrived at the conclusion that between the latitude of Thule and the Dnieper there was a distance of 11,500 stadia I am unable to divine. 5. Eratosthenes being mistaken as to the breadth [of the habitable earth], is necessarily wrong as to its length. The most accurate observers, both ancient and modern, agree that the known length of the habitable earth is more than twice its breadth. Its length I take to be^frpm the [eastern] ex- tremity of Xpdja 3 to the [westernmost] point of Spain ; 4 and its breadth from [the south of] EthiojDia to theTatituae_pf lerne. Eratosthenes, as we have said, reckoning its breadth from the extremity of Ejhiogia toJThule, was forced to extend its length beyond the true limits, that he might make it more than twice as long as the breadth he had assigned to it. He says that India, measured where it is narrowest, 5 is 16,000 stadia to the riyerlndus. If measured from its most prominent capes it extenoTSDOO more. 6 Thence to the Caspian Gates, 14,000.

Strabo probably uses the plural to indicate the capes generally, not confining himself to those which project a few leagues farther than the rest. 7 The Euphrates at Thapsacus, the most frequented passage; hod, El-Der.
