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 trustworthy 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 applicable 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 ordinary 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 Onesicritus and Nearchus, with others of the same class, manage to stammer out a few words [of truth]. Of this we became the more convinced whilst writing the history of Alexander. No faith whatever can be placed in Deimachus and Megasthenes. They coined the fables concerning men with ears large enough to sleep in, men without any mouths, without noses, with only one eye, with spider-legs, and with fingers bent backward. They renewed Homer’s fable concerning the battles of the Cranes and Pygmies, and asserted the latter to be three spans high. They told of ants digging for gold, of Pans with wedge-shaped heads, of serpents swallowing down oxen and stags, horns and all; meantime, as Eratosthenes has observed, reciprocally accusing each other of falsehood. Both of these men were sent ambassadors to Palimbothra,[493]—Megasthenes to Sandrocottus, Deimachus to Allitrochades his son; and such are the notes of their residence abroad, which, I know not why, they thought fit to leave. Patrocles certainly does not resemble them; nor do any other of the authorities consulted by Eratosthenes contain such absurdities. 10. [494]If the meridian of Rhodes and Byzantium has been rightly determined to be the same, then that of Cilicia and Amisus has likewise been rightly determined; many observations having proved that the lines are parallel, and that they never impinge on each other.
