Passage 6.9.8
τούτοις χρῆσαι τὴν Πυθίαν φασίν· ὕστατος ἡρώων Κλεομήδης Ἀστυπαλαιεύς, ὃν θυσίαις τιμᾶ θʼ ἅ τε μηκέτι θνητὸν ἐόντα. Κλεομήδει μὲν οὖν Ἀστυπαλαιεῖς ἀπὸ τούτου τιμὰς ὡς ἥρωι νέμουσι·
They say that the Pythia gave them this oracle: "Last of heroes is Kleomedes of Astypalaia, whom honor with sacrifices as one no longer mortal." From that time onward, therefore, the people of Astypalaia have given Kleomedes the honors due to a hero.
