Passage 3.6.2
Κλεομβρότου δὲ ὁ μὲν πρεσβύτερος τῶν παίδων Ἀγησίπολις παρέσχετο μέγα οὐδὲν ἐς μνήμην, Κλεομένης δὲ ὁ νεώτερος μετὰ τὸν ἀδελφὸν τελευτήσαντα ἔσχε τὴν ἀρχήν. γενομένων δὲ αὐτῷ παίδων Ἀκροτάτου καὶ ἐπʼ αὐτῷ Κλεωνύμου κατήγαγε τὸ χρεὼν Ἀκρότατον ἔτι πρότερον ἢ αὐτὸν Κλεομένην, καὶ ὡς Κλεομένης ἀπέθανεν ὕστερον, ἐς ἀντιλογίαν ἀφίκοντο ὑπὲρ τῆς βασιλείας Κλεώνυμός τε ὁ Κλεομένους καὶ Ἀρεὺς ὁ Ἀκροτάτου. δικάζουσιν οὖν οἱ γέροντες Ἀρεῖ τῷ Ἀκροτάτου καὶ οὐχὶ Κλεωνύμῳ πατρῴαν εἶναι τὴν τιμήν.
Of Cleombrotus' sons, the elder, Agesipolis, offered nothing of great note to memory, whereas the younger, Cleomenes, succeeded to the throne after his brother's death. Cleomenes had two sons, Acrotatus and, later, Cleonymus; fate brought about Acrotatus' death even before that of Cleomenes himself. After Cleomenes subsequently died, a dispute arose over the kingship between Cleonymus, Cleomenes' son, and Areus, the son of Acrotatus. Thereupon, the elders judged that the hereditary kingship belonged to Areus, son of Acrotatus, and not to Cleonymus.
