Meanwhile Xerxes, encamped within sight of Thermopylæ, suffered four days to pass without making any attack: a probable reason may be found in the extreme peril of his fleet, reported to have been utterly destroyed by the storm: but Herodotus assigns a different cause. Xerxes could not believe, according to him, that the Greeks at Thermopylæ, few as they were in number, had any serious intention to resist: he had heard in his march that a handful of Spartans and other Greeks, under an Herakleid leader, had taken post there, but he treated the news with scorn: and when a horseman,—whom he sent to reconnoitre them, and who approached near enough to survey their position, without exciting any attention among them by his presence,—brought back to him a description of the pass, the wall of defence, and the apparent number of the division, he was yet more astonished and puzzled. It happened too, that at the moment when this horseman rode up, the Spartans were in the advanced guard, outside of the wall: some were engaged in gymnastic exercises, others in combing their long hair, and none of them heeded the approach of the hostile spy. Xerxes next sent for the Spartan king, Demaratus, to ask what he was to think of such madness; upon which the latter reminded him of their former conversation at Doriskus, again assuring him that the Spartans in the pass would resist to the death, in spite of the smallness of their number; and adding, that it was their custom, in moments of special danger, to comb their hair with peculiar care. In spite of this assurance from Demaratus, and of the pass not only occupied, but in itself so narrow and impracticable, before his eyes, Xerxes still persisted in believing that the Greeks did not intend to resist, and that they would disperse of their own accord. He delayed the attack for four days: on the fifth he became wroth at the impudence and recklessness of the petty garrison before him, and sent against them the Median and Kissian divisions, with orders to seize them and bring them as prisoners into his presence.[160] [160] Herod. vii, 208, 210. πέμπει ἐς αὐτοὺς Μήδους τε καὶ Κισσίους θυμωθεὶς, ἐντειλάμενός σφεας ζωγρήσαντας ἄγειν ἐς ὄψιν τὴν ἑωϋτοῦ.
