2. An Athenian general, father of the poet Menander, was sent out to the Thracian
Chersonesus about de
Chers. p. 91, Philipp. iii. p. 114; Pseud.-Dem. (de
Halonn. pp. 86, 87.) Disputes having arisen about their boundaries between these
settlers and the Cardians, the latter were supported, but not with arms in the first instance,
by Philip of Macedon, who, when the Athenians remonstrated, proposed that their quarrel with
Cardia should be referred to arbitration. This proposal being indignantly rejected, Philip
sent troops to the assistance of the Cardians, and Diopeithes retaliated by ravaging the
maritime district of Thrace, which was subject to the Macedonians, while Philip was absent in
the interior of the same country on his expedition against Teres and Cersobleptes. Philip sent
a letter of remonstrance to Athens, and Diopeithes was arraigned by the Macedonian party, not
only for his aggression on the king's territory, but also for the means (unjust doubtless and
violent, but common enough with all Athenian generals at the time,) to which he resorted for
the support of his mercenaries. He was defended by Demosthenes in the oration, still extant,
on the Chersonese, ad Dem. de Chers.; Dem. de Chers. passim; Phil. Ep. ad Ath. pp. 159, 160, 161.)
The enmity of Diopeithes to Philip appears to have recommended him to the favour of the king
of Persia (Artaxerxes III.), who, as we learn from Aristotle, sent him some valuable presents,
which did not arrive, however, till after his death. (Arist. Rhet.
