Derdas
(
*De/rdas), a prince of Elymia or Elimeia, and probably of the same family as the cousin of Perdiccas II. mentioned above.
As he had reason, from the example of Amyntas II. [see p. 154b.], to fear the growing power of Olynthus, he zealously and effectually aided the Spartans in their war with that state, from B. C. 382 to 379. (
Xen. Hell. 5.2,
3;
Diod. 15.19-
23.) We learn from Theopompus (apud
Athen. x. p. 436d.), that he was taken prisoner by the Olynthians, but it does not appear on what occasion; nor is it certain whether he is the same Derdas to whom Aristotle alludes. (
Polit. 5.10, ed. Bekk.) Derdas, whose sister Phila was one of the wives of Philip, was probably a different person, though of the same family. (Ath. xiii. p. 557c.)
