On board the Trœzenian vessel, which was the first to be captured, they found a soldier named Leon, of imposing stature: this man was immediately taken to the ship’s head and slain, as a presaging omen in the approaching contest: perhaps, observes the historian, his name may have contributed to determine his fate.[144] The ten Persian ships advanced no farther than the dangerous rock Myrmêx, between Skiathos and the mainland, which had been made known to them by a Greek navigator of Skyros, and on which they erected a pillar to serve as warning for the coming fleet. Still, so intense was the alarm which their presence—communicated by fire-signals[145] from Skiathos, and strengthened by the capture of the three look-out ships—inspired to the fleet at Artemisium, that they actually abandoned their station, believing that the entire fleet of the enemy was at hand.[146] They sailed up the Eubœan strait to Chalkis, as the narrowest and most defensible passage; leaving scouts on the high lands to watch the enemy’s advance. [144] Herodot. vii, 180. τάχα δ’ ἄν τι καὶ τοῦ ὀνόματος ἐπαύροιτο. Respecting the influence of a name and its etymology, in this case unhappy for the possessor, compare Herodot. ix, 91; and Tacit. Hist. iv, 53. [145] For the employment of fire-signals, compare Livy, xxviii, 5; and the opening of the Agamemnon of Æschylus, and the same play, v. 270, 300; also Thucydides, iii, 22-80. [146] Herodot. vii, 181, 182, 183. Probably this sudden retreat was forced upon the generals by the panic of their troops, similar to that which king Leonidas, more powerful than Eurybiadês and Themistoklês, had found means to arrest at Thermopylæ. It ruined for the time the whole scheme of defence, by laying open the rear of the army at Thermopylæ to the operations of the Persian fleet. But that which the Greeks did not do for themselves was more than compensated by the beneficent intervention of their gods, who opposed to the invader the more terrible arms of storm and hurricane. He was allowed to bring his overwhelming host, land-force as well as naval, to the brink of Thermopylæ and to the coast of Thessaly, without hindrance or damage; but the time had now arrived when the gods appeared determined to humble him, and especially to strike a series of blows at his fleet which should reduce it to a number not beyond what the Greeks could contend with.[147] Amidst the general terror which pervaded Greece, the Delphians were the first to earn the gratitude of their countrymen by announcing that divine succor was at hand.[148] On entreating advice from their own oracle, they were directed to pray to the Winds, who would render powerful aid to Greece. Moreover, the Athenian seamen, in their retreat at Chalkis, recollecting that Boreas was the husband of the Attic princess or heroine Oreithyia, daughter of their ancient king Erechtheus, addressed fervent prayers to their son-in-law for his help in need.
