Note 660 — Chapter LXXXVII · FROM THE COMMENCEMENT OF THE SACRED WAR TO THAT OF THE OLYNTHIAN WAR. (continued 2)

Demosthenes, Olynth. iii. p. 29. s. 5 (delivered in the latter half of 350 B. C.)

... ἀπηγγέλθη Φίλιππος ὑμῖν ἐν Θρᾴκῃ, τρίτον ἢ τέταρτον ἔτος τουτὶ, Ἡραῖον τεῖχος πολιορκῶν, τότε τοίνυν μὴν μὲν ἦν Μαιμακτηριὼν, etc.

This Thracian expedition of Philip (alluded to also in Demosthenes, Olynth. i. p. 13. s. 13) stands fixed to the date of November 352 B. C., on reasonably good grounds.

That the town or fortress called Ἡραῖον Τεῖχος was near to the Chersonese, cannot be doubted. The commentators identify it with Ἡραῖον, mentioned by Herodotus (iv. 90) as being near Perinthus. But this hypothesis is open to much doubt. Ἡραῖον Τεῖχος is not quite the same as Ἡραῖον; nor was the latter place very near to the Chersonese; nor would Philip be yet in a condition to provoke or menace so powerful a city as Perinthus—though he did so ten years afterwards. (Diodor. xvi. 74).

I cannot think that we know where Ἡραῖον Τεῖχος was situated; except that it was in Thrace, and near the Chersonese.
