Passage 4.23.4
ἑάλω δὲ ἡ Εἶρα καὶ ὁ πόλεμος ὁ δεύτερος Λακεδαιμονίων καὶ Μεσσηνίων τέλος ἔσχεν Ἀθηναίοις ἄρχοντος Αὐτοσθένους, ἔτει πρώτῳ τῆς ὀγδόης τε καὶ εἰκοστῆς Ὀλυμπιάδος, ἣν ἐνίκα Χίονις Λάκων.
Eira was taken, and the second war between the Lacedaemonians and the Messenians came to an end in the year when Autosthenes was archon at Athens, in the first year of the twenty-eighth Olympiad, in which Chionis the Spartan was victor.
