Xerxes passed into Europe, not as Darius did at the half-mile crossing of the Bosphorus, but at the Hellespont (the Dardanelles). In his account of the assembling of the great army, and its march from Sardis to the Hellespont, the poet in Herodotus takes possession of the historian. The great host passes in splendour by Troy, and Xerxes, who although a Persian and a Barbarian, seems to have had the advantages of a classical education, turns aside, says our historian, to visit the citadel of Priam. The Hellespont was bridged at Abydos, and upon a hill was set a marble throne from which Xerxes surveyed the whole array of his forces. “And seeing all the Hellespont covered over with the ships and all the shores and the plains of Abydos full of men, then Xerxes pronounced himself a happy man, and after that he fell to weeping. Artabanus, his uncle, therefore perceiving him--the same who at first boldly declared his opinion advising Xerxes not to march against Hellas--this man, I say, having observed that Xerxes wept, asked as follows: ‘O king, how far different from one another are the things which thou hast done now and a short while before now! for having pronounced thyself a happy man, thou art now shedding tears.’ He said: ‘Yea, for after I had reckoned up, it came into my mind to feel pity at the thought how brief was the whole life of man, seeing that of these multitudes not one will be alive when a hundred years have gone by.’” This may not be exact history, but it is great poetry. It is as splendid as anything in _The Dynasts_. The Persian fleet, coasting from headland to headland, accompanied this land multitude during its march southward; but a violent storm did the fleet great damage and 400 ships were lost, including much corn transport. At first the united Hellenes marched out to meet the invaders at the Vale of Tempe near Mount Olympus, but afterwards retreated through Thessaly, and chose at last to await the advancing Persians at a place called Thermopylæ, where at that time--2300 years have altered these things greatly--there was a great cliff on the landward side and the sea to the east, with a track scarcely wide enough for a chariot between. The great advantage to the Greeks of this position at Thermopylæ was that it prevented the use of either cavalry or chariots, and narrowed the battle front so as to minimize their numerical inequality. And there the Persians joined battle with them one summer day in the year 480 B.C.
