108 STRABO. BOOK n. of Alexander took but a very hasty view of every thing [in India], but Alexander himself a more exact one, causing the whole country to be described by men well acquainted with it. Which description he says was afterwards put into his hands by Xenocles the treasurer. 7. Again, in the second volume of his Commentaries, Hip- parchus accuses Eratosthenes of himself throwing discredit on the statement of Patrocles, on account of his differing with Me- gasthenes, as to the length of India on its northern side ; 1 Me- gasthenes stating the length at 16,000 stadia, and Patrocles at 1000 less. Being biassed by a certain Itinerary, Eratos- thenes was led to reject. them both on account of this discre- pancy, and to follow the Itinerary. If then merely the differ- ence of 1000 stadia is sufficient to cause the authority of Patrocles to be rejected, how much more should this be the case when we find a difference of 8000 stadia between his statement and that of two writers who agree perfectly in theirs, that the breadth of India is 20,000 stadia, while he gives only 12,000 ! 8. We reply, that [Eratosthenes] did not object [to the statement of Patrocles] merely because it differed [from that of Megasthenes], but because the statement of this latter as to the stadia was confirmed by the Itinerary, an authority of no mean importance. There is nothing wonderful in this, that though a certain statement may be credible, another may be more credible ; and that while in some instances we follow the former, in others we may dissent from it on finding a more trust-worthy guide. It is ridiculous to say that the greater the difference of one writer from others, the less he should be trusted. On the contrary, such a rule would be more applica- ble in regard to small differences ; for in little particulars the ordinary observer and the man of great ability are equally liable to err. On the other hand, in great matters, the ordi- nary run of men are more like to be deceived than the man of superior talent, to whom consequently in such cases greater deference is paid. 9. Generally speaking, the men who hitherto have written on the affairs of India, were a set of liars. Deimachus holds the first place in the list, Megasthenes comes next, while 1 The length of India is its measurement from -west to east.
