1911 Encyclopædia Britannica/Leotychides
According to Diodorus (xi. 48) Leotychides reigned twenty-two, his successor Archidamus forty-two years. The total duration of the two reigns, sixty-four years, we know to be correct, for Leotychides came to the throne in 491 and Archidamus (q.v.) died in 427. On this basis, then, Leotychides’s exile would fall in 469 and the Thessalian expedition in that or the preceding year (so E. Meyer, Geschichte des Altertums, iii. § 287). But Diodorus is not consistent with himself; he attributes (xi. 48) Leotychides’s death to the year 476–475 and he records (xii. 35) Archidamus’s death in 434–433, though he introduces him in the following years at the head of the Peloponnesian army (xii. 42, 47, 52). Further, he says expressly that Leotychides ἐτελεύτησεν ἄρξας ἔτη εἴκοσι καὶ δύο, i.e. he lived twenty-two years after his accession. The twenty-two years, then, may include the time which elapsed between his exile and his death. In that case Leotychides died in 469, and 476–475 may be the year in which his reign, though not his life, ended. This date seems, from what we know of the political situation in general, to be more probable than the later one for the Thessalian campaign.

Beloch’s view (Griech. Geschichte, i. 455, note 2) that the expedition took place in 476, the trial and flight in 469, is not generally accepted. (M. N. T.)
