Passage 1.31.3
Κραναὸν δὲ τὸν βασιλεύσαντα Ἀθηναίων ὅτι μὲν ἐξέβαλεν Ἀμφικτύων κηδεστὴν ὄντα, ἔτι πρότερον εἴρηταί μοι· φυγόντα δὲ αὐτὸν σὺν τοῖς στασιώταις ἐς τὸν δῆμον τὸν Λαμπτρέα ἀποθανεῖν τε αὐτοῦ καὶ ταφῆναί φασι, καὶ ἔστι καὶ ἐς ἐμὲ καὶ ἐν τοῖς Λαμπτρεῦσι Κραναοῦ μνῆμα. Ἴωνος δὲ τοῦ Ξούθου ---καὶ γὰρ οὗτος ᾤκησε παρὰ Ἀθηναίοις καὶ Ἀθηναίων ἐπὶ τοῦ πολέμου τοῦ πρὸς Ἐλευσινίους ἐπολεμάρχησε ---τάφος ἐν Ποταμοῖς ἐστι τῆς χώρας.
I have already related earlier that Cranaus, who ruled over the Athenians, was expelled by Amphictyon, despite being his kinsman by marriage. They say that, fleeing with his supporters to the deme Lamptrae, Cranaus there died and was buried. His tomb remains among the people of Lamptrae even to my days. As for Ion, the son of Xuthus—since he too lived among the Athenians and served as their commander in the war against the Eleusinians—his tomb is located in the region belonging to the deme of Potamoi.
