Passage 3.7.6
οὐ μὴν ἄπαις ἐτελεύτησεν ὁ Ἀρχίδαμος, Ζευξίδαμον δὲ ἀπολιπὼν υἱόν. Ζευξιδάμου δὲ Ἀναξίδαμος ὁ παῖς ἐκδέχεται τὴν ἀρχήν· ἐπὶ τούτου Μεσσήνιοι φεύγουσιν ἐκ Πελοποννήσου, πολέμῳ τὸ δεύτερον κρατηθέντες ὑπὸ Σπαρτιατῶν. Ἀναξιδάμου δὲ υἱὸς ἐγένετο Ἀρχίδαμος, Ἀρχιδάμου δὲ Ἀγησικλῆς· καί σφισιν ὑπῆρξεν ἀμφοτέροις τὸν βίον διατελέσαι πάντα ἐν ἡσυχίᾳ καὶ πολέμων οὖσιν ἐκτός.
Nevertheless, Archidamus did not die childless, but left behind his son Zeuxidamus. Zeuxidamus' son Anaxidamus succeeded to the throne. During his reign, the Messenians fled from the Peloponnese, having been overcome by the Spartans in war for the second time. The son of Anaxidamus was Archidamus, and the son of Archidamus was Agesicles; these two both happened to pass the entirety of their lives in peace, being free from wars.
