2.1.4

πρὸς δὲ τὴν ἀπόφασιν ταύτην ὁ Ἵππαρχος ἀντιλέγει διαβάλλων τὰς πίστεις· οὐδὲ γὰρ Πατροκλέα πιστὸν εἶναι, δυεῖν ἀντιμαρτυρούντων αὐτῷ Δηιμάχου τε καὶ Μεγασθένους, οἳ καθʼ οὓς μὲν τόπους δισμυρίων εἶναι σταδίων τὸ διάστημά φασι τὸ ἀπὸ τῆς κατὰ μεσημβρίαν θαλάττης, καθʼ οὓς δὲ καὶ τρισμυρίων· τούτους τε δὴ τοιαῦτα λέγειν καὶ τοὺς ἀρχαίους πίνακας τούτοις ὁμολογεῖν. ἀπίθανον δή που νομίζει τὸ μόνῳ δεῖν πιστεύειν Πατροκλεῖ, παρέντας τοὺς τοσοῦτον ἀντιμαρτυροῦντας αὐτῷ, καὶ διορθοῦσθαι παρʼ αὐτὸ τοῦτο τοὺς ἀρχαίους πίνακας, ἀλλὰ μὴ ἐᾶν οὕτως, ἕως ἄν τι πιστότερον περὶ αὐτῶν γνῶμεν.

Hipparchus tries to invalidate this view of Eratosthenes, by sneering at the proofs on which it rests. Patrocles, he says, merits little credit, being contradicted by the two writers Deimachus and Megasthenes, who say that the distance taken from the southern ocean, is in some places 20,000, in others 30,000 stadia; that in this assertion they are supported by the ancient charts, and he considers it absurd to require us to put implicit faith in Patrocles alone, when there is so much testimony against him; or that the ancient charts should be corrected; but rather that they should be left as they are until we have something more certain on the subject.
