Note 539 — Chapter LXXIX · FROM THE FOUNDATION OF MESSENE AND MEGALOPOLIS TO THE DEATH OF PELOPIDAS.
Reading edition
Demosthen. cont. Aristokrat. p. 669, s. 150.
μισθοῖ πάλιν αὑτὸν (Charidemus) τοῖς Ὀλυνθίοις, τοῖς ὑμετέροις ἐχθροῖς καὶ τοῖς ἔχουσιν Ἀμφίπολιν κατὰ τοῦτον τὸν χρόνον.
Demosthenes is here speaking of the time when Timotheus superseded Iphikrates in the command, that is, about 365-364 B.C. But we are fairly entitled to presume that the same is true of 369 or 368 B.C.
