Note 897 — Chapter LXXXIX · FROM THE CAPTURE OF OLYNTHUS TO THE TERMINATION OF THE SACRED WAR BY PHILIP.

That the Phokians could not maintain Thermopylæ without the aid of Athens—and that Philip could march to the frontier of Attica, without any intermediate obstacle to prevent him, if Olynthus were suffered to fall into his hand—is laid down emphatically by Demosthenes in the first Olynthiac, nearly four years before the month of Skirrophorion, 346 B. C.

Ἂν δ᾽ ἐκεῖνα Φίλιππος λάβῃ, τίς αὐτὸν κωλύσει δεῦρο βαδίζειν; Θηβαῖοι; οἳ, εἰ μὴ λίαν πικρὸν εἰπεῖν, καὶ συνεισβαλοῦσιν ἑτοίμως. Ἀλλὰ Φωκεῖς; οἱ τὴν οἰκείαν οὐχ οἷοί τε ὄντες φυλάττειν, ἐὰν μὴ βοηθήσεθ᾽ ὑμεῖς (Demosth. Olynth. i. p. 16).
