Passage 10.4.5
ἐνταῦθα ἐπὶ τῇ χαράδρᾳ καὶ Τιτυοῦ μνῆμά ἐστι· περίοδος μὲν τοῦ χώματος τρίτον μάλιστά που σταδίου, τὸ δὲ ἔπος τὸ ἐν Ὀδυσσείᾳ κείμενον ἐν δαπέδῳ· ὁ δʼ ἐπʼ ἐννέα κεῖτο πέλεθρα Hom. Od. 11.577 οὐκ ἐπὶ μεγέθει πεποιῆσθαι τοῦ Τιτυοῦ φασιν, ἀλλʼ ἔνθα ὁ Τιτυὸς ἐτέθη, Πλέθρα ἐννέα ὄνομα εἶναι τῷ χωρίῳ.
Here by the gorge is also the tomb of Tityos; the circumference of the mound measures approximately one-third of a stade. The line from the Odyssey is inscribed on it: "And he lay stretched over nine plethra." They say, however, that the reference is not intended to describe Tityos' actual size, but rather that the place where Tityos was buried is called "Nine Plethra."
