When the king of Persia sent messengers into Greece, with an interpreter, to demand earth and water, as an acknowledgment of subjection, Themistocles, by the consent of the people, seized upon the interpreter, and put him to death, for presuming to publish the barbarian orders and decrees in the Greek language; this is one of the actions he is commended for, as also for what he did to Arthmius of Zelea, who brought gold from the king of Persia to corrupt the Greeks, and was, by an order from Themistocles, degraded and disfranchised, he and his children and his posterity; but that which most of all redounded to his credit was, that he put an end to all the civil wars of Greece, composed their differences, and persuaded them to lay aside all enmity during the war with the Persians; and in this great work, Chileus the Arcadian was, it is said, of great assistance to him.
Having taken upon himself the command of the Athenian forces, he immediately endeavoured to persuade the citizens to leave the city, and to embark upon their galleys, and meet with the Persians at a great distance from Greece; but many being against this, he led a large force, together with the Lacedaemonians, into Tempe, that in this pass they might maintain the safety of Thessaly, which had not as yet declared for the king; but when they returned without performing anything, and it was known that not only the Thessalians, but all as far as Boeotia, was going over to Xerxes, then the Athenians more willingly hearkened to the advice of Themistocles to fight by sea, and sent him with a fleet to guard the straits of Artemisium.
When the contingents met here, the Greeks would have the Lacedaemonians to command, and Eurybiades to be their admiral; but the Athenians, who surpassed all the rest together in number of vessels, would not submit to come after any other, till Themistocles, perceiving the danger of the contest, yielded his own command to Eurybiades, and got the Athenians to submit, extenuating the loss by persuading them, that if in this war they behaved themselves like men, he would answer for it after that, that the Greeks, of their own will, would submit to their command. And by this moderation of his, it is evident that he was the chief means of the deliverance of Greece, and gained the Athenians the glory of alike surpassing their enemies in valour, and their confederates in wisdom.
As soon as the Persian armada arrived at Aphetae, Eurybiades was astonished to see such a vast number of vessels before him, and being informed that two hundred more were sailing around behind the island of Sciathus, he immediately determined to retire farther into Greece, and to sail back into some part of Peloponnesus, where their land army and their fleet might join, for he looked upon the Persian forces to be altogether unassailable by sea. But the Euboeans, fearing that the Greeks would forsake them, and leave them to the mercy of the enemy, sent Pelagon to confer privately with Themistocles, taking with him a good sum of money, which, as Herodotus reports, he accepted and gave to Eurybiades. In this affair none of his own countrymen opposed him so much as Architeles, captain of the sacred galley, who, having no money to supply his seamen, was eager to go home; but Themistocles so incensed the Athenians against them, that they set upon him and left him not so much as his supper, at which Architeles was much surprised, and took it very ill; but Themistocles immediately sent him in a chest a service of provisions, and at the bottom of it a talent of silver, desiring him to sup tonight, and to-morrow provide for his seamen; if not, he would report it among the Athenians that he had received money from the enemy. So Phanias the Lesbian tells the story.
Though the fights between the Greeks and Persians in the straits of Euboea were not so important as to make any final decision of the war, yet the experience which the Greeks obtained in them was of great advantage; for thus, by actual trial and in real danger, they found out that neither number of ships, nor riches and ornaments, nor boasting shouts, nor barbarous songs of victory, were any way terrible to men that knew how to fight, and were resolved to come hand to hand with their enemies; these things they were to despise, and to come up close and grapple with their foes. This Pindar appears to have seen, and says justly enough of the fight at Artemisium, that-"There the sons of Athens set The stone that freedom stands on yet."For the first step towards victory undoubtedly is to gain courage, Artemisium is in Euboea, beyond the city of Histiaea, a sea-beach open to the north; most nearly opposite to it stands Olizon, in the country which formally was under Philoctetes; there is a small temple there, dedicated to Diana, surnamed of the Dawn, and trees about it, around which again stand pillars of white marble; and if you rub them with your hand, they send forth both the smell and colour of saffron. On one of these pillars these verses are engraved:-"With numerous tribes from Asia's region brought The sons of Athens on these waters fought;Erecting, after they had quelled the Mede, To Artemis this record of the deed."There is a place still to be seen upon this shore, where, in the middle of a great heap of sand, they take out from the bottom a dark powder like ashes, or something that has passed the fire; and here, it is supposed, the shipwrecks and bodies of the dead were burnt.
But when news came from Thermopylae to Artemisium informing them that king Leonidas was slain, and that Xerxes had made himself master of all the passages by land, they returned back to the interior of Greece, the Athenians having the command of the rear, the place of honour and danger, and much elated by what had been done.
