XVIII. Yet when Philip, excited by his success at Amphissa, suddenly marched to Elatea and made himself master of Phokis, when all the Athenians were panic-stricken, and no one dared to ascend the bema, or knew what to say, Demosthenes alone came forward and advised them to stand by the Thebans; and after having, after his wont, encouraged and comforted the people, he was sent with some others as ambassador to Thebes. We learn from the historian Marsyas that Philip, too, sent the Macedonians Amyntas and Klearchus, the Thessalian Daochus, and Thrasydaeus to Thebes to argue on his behalf. The Thebans on this occasion saw clearly enough on which side their interests lay, for the sufferings they had just endured in the Phokian war were still fresh in their memories; but we read in the history of Theopompus that the eloquence of Demosthenes so roused and inflamed their courage that all cold-blooded calculation of the chances, fear of the enemy, and considerations of expediency were entirely lost sight of in the honourable enthusiasm created by his speech. So powerful did his oratory prove, that Philip at once sent an embassy to ask for terms of peace, while Greece stood erect and watchful. Not only the Athenian generals, but even the Boeotarchs took their orders from Demosthenes, and he was as powerful in the public assembly of the Thebans as in that of Athens, being beloved by both nations and possessed of a power which was not beyond his deserts, as Theopompus says, but which he well deserved.

But some fatal destiny seemed now to have brought round the hour for the extinction of the liberties of Greece, and both counteracted his efforts, and also gave many ominous indications of what was to come. The Pythia at Delphi uttered terrible predictions, and an old oracle of the Sibyls was in every one's mouth, which ran as follows:-- "Far from the battle, on that fatal day Beside Thermodon may I flee away, Or view it as an eagle from the sky; There shall the vanquished weep, the victor die." It is said that the Thermodon is a little rivulet near my own town of Chæronea which runs into the Kephisus. We Chæroneans nowadays do not know of any rivulet which is so called, but we suppose that the stream which we call Hæmon was at that period called the Thermodon; for it runs past the temple of Herakles, where the Greek army encamped: and we imagine that when the battle took place this stream was filled with blood and corpses, and became known by its present name. Yet the historian Douris writes that the Thermodon was not a river at all, but that some men while digging a trench round their tent found a small stone image, with an inscription saying that it represented a man named Thermodon carrying a wounded Amazon in his arms. Concerning this there was another oracle current, as follows:-- "Watch for Thermodon's field, thou sable crow, There shalt thou feed on human flesh enow."
