Passage 3.7.9
Λεωτυχίδης δὲ ἀντὶ Δημαράτου γενόμενος βασιλεὺς μετέσχε μὲν Ἀθηναίοις καὶ Ἀθηναίων τῷ στρατηγῷ Ξανθίππῳ τῷ Ἀρίφρονος τοῦ ἔργου τοῦ πρὸς Μυκάλῃ, ἐστράτευσε δὲ ὕστερον τούτων καὶ ἐπὶ τοὺς Ἀλευάδας ἐς Θεσσαλίαν· καί οἱ καταστρέψασθαι Θεσσαλίαν πᾶσαν ἐξὸν ἅτε ἀεὶ νικῶντι ἐν ταῖς μάχαις, δῶρα ἔλαβε παρὰ τῶν Ἀλευαδῶν.
Leotychides, who became king in place of Demaratus, took part with the Athenians and their general Xanthippus, the son of Ariphron, in the action at Mycale. Afterwards he also campaigned against the Aleuadae in Thessaly; and though it was in his power to subdue all Thessaly, as he was consistently victorious in battle, he accepted gifts from the Aleuadae.
