Passage 3.8.10
τότε οὖν Λεωτυχίδης μὲν ἐς Ἀγησίλαον ταῦτα ἔφασκεν εἰρῆσθαι, τὸν γὰρ δὴ ἕτερον τῶν ποδῶν ἐπεπήρωτο ὁ Ἀγησίλαος· Ἀγησίλαος δὲ ἐς Λεωτυχίδην αὐτὰ ἔτρεπεν οὐ γνήσιον ὄντα Ἄγιδος. Λακεδαιμόνιοι δέ, καίπερ ἐπὶ σφίσιν ὄν, οὐκ ἐπανήγαγον τὸ ἀμφισβήτημα ἐς Δελφούς· αἴτιος δʼ ἐμοὶ δοκεῖν Λύσανδρος ἐγένετο ὁ Ἀριστοκρίτου Ἀγησιλάῳ συσπεύδων ἐξ ἅπαντος τὴν βασιλείαν γενέσθαι.
At that time, Leotychides directed these words against Agesilaus, for Agesilaus was indeed lame in one of his feet; but Agesilaus turned the charge back against Leotychides, saying that he was not the legitimate son of Agis. Although the decision rested with them, the Lacedaemonians did not refer this dispute to Delphi. The reason, in my opinion, was Lysander, the son of Aristocritus, who earnestly supported Agesilaus in every way, so that the royal power might pass to him.
