Ἰνδικά 7.2: Strabo II, p. 77

7.2

Δηιμάχου φήσαντος μηδαμοῦ τῆς Ἰνδικῆς μήτ’ ἀποκρύπτεσθαι τὰς ἄρκτους μήτ’ ἀντιπίπτειν τὰς σκιὰς ὅπερ ὑπείληφεν ὁ Μεγασθένης.

Hipparchos controverts this view, urging the futility of the proofs on which it rests. Patrokles, he says, is unworthy of trust, opposed as he is by two competent authorities, Deimachos and Megasthenes, who state that in some places the distance from the southern sea is 20,000 stadia, and in others 30,000. Such, he says, is the account they give, and it agrees with the ancient charts of the country.
