Note 602 — Chapter LXXXVII · FROM THE COMMENCEMENT OF THE SACRED WAR TO THAT OF THE OLYNTHIAN WAR.
Reading edition
The oration De Symmoriis is placed by Dionysius of Halikarnassus in the archonship of Diotimus, 354-353 B. C. (Dionys. Hal. ad Ammæum. p. 724). And it is plainly composed prior to the expedition sent by the Thebans under Pammenês to assist the revolted Artabazus against the Great King; which expedition is placed by Diodorus (xvi. 34) in the ensuing year 353-352 B. C. Whoever will examine the way in which Demosthenes argues, in the Oration De Symmoriis (p. 187. s. 40-42), as to the relations of the Thebans with Persia—will see that he cannot have known anything about assistance given by the Thebans to Artabazus against Persia.
