Passage 1.35.7
τὸ δʼ ἐμοὶ θαῦμα παρασχόν, Λυδίας τῆς ἄνω πόλις ἐστὶν οὐ μεγάλη Τημένου θύραι· ἐνταῦθα παραραγέντος λόφου διὰ χειμῶνα ὀστᾶ ἐφάνη τὸ σχῆμα παρέχοντα ἐς πίστιν ὡς ἔστιν ἀνθρώπου, ἐπεὶ διὰ μέγεθος οὐκ ἔστιν ὅπως ἂν ἔδοξεν. αὐτίκα δὲ λόγος ἦλθεν ἐς τοὺς πολλοὺς Γηρυόνου τοῦ Χρυσάορος εἶναι μὲν τὸν νεκρόν, εἶναι δὲ καὶ τὸν θρόνον· καὶ γὰρ θρόνος ἀνδρός ἐστιν ἐνειργασμένος ὄρους λιθώδει προβολῇ· καὶ χείμαρρόν τε ποταμὸν Ὠκεανὸν ἐκάλουν καὶ βοῶν ἤδη κέρασιν ἔφασάν τινας ἐντυχεῖν ἀροῦντας, διότι ἔχει λόγος βοῦς ἀρίστας θρέψαι τὸν Γηρυόνην.
But what struck me as remarkable is this: there is a small city called Temenothyrae in Upper Lydia. Here, when a hillside had collapsed due to heavy rainfall, bones were exposed, appearing in their form plainly human; however, their size was so extraordinary that no one could reasonably consider them human. Immediately among the common people spread the story that the remains belonged to Geryon, the son of Chrysaor, and that his throne was there as well. Indeed, there is a throne carved into a rocky projection of the mountain in the shape suitable for a man. Moreover, they named a torrent nearby the Ocean, and some even claimed that men, while ploughing their fields, encountered horns of cattle, since tradition holds that Geryon reared cattle of surpassing excellence.
