Passage 9.41.6
ἔστι δὲ ὑπὲρ τὴν πόλιν κρημνὸς Πετραχὸς καλούμενος· Κρόνον δὲ ἐθέλουσιν ἐνταῦθα ἀπατηθῆναι δεξάμενον ἀντὶ Διὸς πέτρον παρὰ τῆς Ῥέας, καὶ ἄγαλμα Διὸς οὐ μέγα ἐστὶν ἐπὶ κορυφῇ τοῦ ὄρους.
Above the city there is a cliff called Petrachos. They say that it was here that Kronos was deceived, accepting from Rhea a stone instead of Zeus. On the summit of the mountain there stands a statue of Zeus, not large in size.
