Passage 4.24.3
ἀλλὰ γὰρ πρότερον τούτων συνέπεσεν ἀποθανεῖν αὐτῷ νοσήσαντι, οὐ γὰρ ἔδει συμφορὰν οὐδεμίαν Λακεδαιμονίοις ἔτι ἐξ Ἀριστομένους γενέσθαι. τελευτήσαντι δὲ αὐτῷ Δαμάγητος καὶ οἱ Ῥόδιοι μνῆμά τε ἐπιφανὲς ἐποίησαν καὶ ἔνεμον ἀπὸ ἐκείνου τιμάς. τὰ μὲν δὴ λεγόμενα ἐς τοὺς Διαγορίδας καλουμένους ἐν Ῥόδῳ, γεγονότας δὲ ἀπὸ Διαγόρου τοῦ Δαμαγήτου τοῦ Δωριέως τοῦ Δαμαγήτου τε καὶ τῆς Ἀριστομένους θυγατρός, παρῆκα, μὴ οὐ κατὰ καιρὸν δοκοίην γράφειν·
However, before these things could occur, Aristomenes fell ill and died; for it was not ordained that the Lacedaemonians should suffer any further misfortune at the hands of Aristomenes. When he passed away, Damagetus and the Rhodians erected a notable tomb in his honor and thenceforth bestowed upon him heroic honors. But as for the traditions relating to the family called the Diagoridae in Rhodes, descended from Diagoras, the son of Damagetus, himself son of Dorieus, who was the son of Damagetus and of Aristomenes' daughter, I shall omit them, lest my account appear irrelevant.
