Passage 9.31.4
Βοιωτῶν δὲ οἱ περὶ τὸν Ἑλικῶνα οἰκοῦντες παρειλημμένα δόξῃ λέγουσιν ὡς ἄλλο Ἡσίοδος ποιήσειεν οὐδὲν ἢ τὰ Ἔργα· καὶ τούτων δὲ τὸ ἐς τὰς Μούσας ἀφαιροῦσι προοίμιον, ἀρχὴν τῆς ποιήσεως εἶναι τὸ ἐς τὰς Ἔριδας λέγοντες· καί μοι μόλυβδον ἐδείκνυσαν, ἔνθα ἡ πηγή, τὰ πολλὰ ὑπὸ τοῦ χρόνου λελυμασμένον·
But the Boeotians dwelling around Helicon, following a widely held opinion among them, say that Hesiod composed no work other than the Works; moreover, from this poem itself they remove the proem addressed to the Muses, asserting that its true beginning is the part concerning the Strifes. They also showed me a lead tablet at the spring, seriously damaged by age.
