Serving as these Greeks in the fleet were, at a distance from their own homes, and having left a powerful army of Persians and Greeks under Mardonius in Bœotia, they were of course full of anxiety lest his arms might prove victorious and extinguish the freedom of their country. It was under these feelings of solicitude for their absent brethren that they disembarked, and were made ready for attack by the afternoon. But it was the afternoon of an ever-memorable day,—the fourth of the month Boëdromion (about September) 479 B. C. By a remarkable coincidence, the victory of Platæa in Bœotia had been gained by Pausanias that very morning. At the moment when the Greeks were advancing to the charge, a divine phêmê, or message, flew into the camp,—whilst a herald’s staff was seen floated to the shore by the western wave, the symbol of electric transmission across the Ægean;—the revelation, sudden, simultaneous, irresistible, struck at once upon the minds of all, as if the multitude had one common soul and sense, acquainting them that on that very morning their countrymen in Bœotia had gained a complete victory over Mardonius. At once the previous anxiety was dissipated, and the whole army, full of joy and confidence, charged with redoubled energy. Such is the account given by Herodotus,[398] and doubtless universally accepted in his time, when the combatants of Mykalê were alive to tell their own story: he moreover mentions another of those coincidences which the Greek mind always seized upon with so much avidity, there was a chapel of Eleusinian Dêmêtêr close to the field of battle at Mykalê as well as at Platæa. Diodorus and other later writers,[399] who wrote when the impressions of the time had vanished, and when divine interventions were less easily and literally admitted, treat the whole proceeding as if it were a report designedly circulated by the generals, for the purpose of encouraging their army.
