to be cut off, and the sea itself scourged with three hundred lashes. This insane wrath being expended, the monarch caused the work to be at once reconstructed, this time by the aid of Greek engineers. Two bridges were built side by side upon more than six hundred large ships, moored with strong anchors, with their heads toward the Ægean. Over each bridge were sketched six vast cables, which held the ships together, and over these were laid planks of wood, upon which a causeway was formed of wood and earth, with a high palisade on each side. To facilitate his march, Xerxes also constructed a canal across the isthmus which connects Mount Athos with the main land, on which were employed Phœnician engineers. The men employed in digging the canal worked under the whip. Bridges were also thrown across the river Strymon. (M429) These works were completed while Xerxes wintered at Sardis. From that city he dispatched heralds to all the cities of Greece, except Sparta and Athens, to demand the usual tokens of submission—earth and water. He also sent orders to the maritime cities of Thrace and Macedonia to prepare dinner for himself and hosts, as they passed through. Greece was struck with consternation as the news reached the various cities of the vast forces which were on the march to subdue them. The army proceeded from Sardis, in the spring, in two grand columns, between which was the king and guards and select troops—all native Persians, ten thousand foot and ten thousand horse. From Sardis the hosts of Xerxes proceeded to Abydos, through Ilium, where his two bridges across the Hellespont awaited him. From a marble throne the proud and vainglorious monarch saw his vast army defile over the bridges, perfumed with frankincense and strewed with myrtle boughs. One bridge was devoted to the troops, the other to the beasts and baggage. The first to cross were the ten thousand household troops, called Immortals, wearing garlands on their heads; then followed Xerxes himself in his gilded chariot, and then the rest of the army. It occupied seven days for the vast hosts to cross the bridge. Xerxes then directed his march to Doriscus, in Thrace, near the mouth of the Hebrus, where he joined his fleet. There he took a general review, and never, probably, was so great an army marshaled before or since, and composed of so many various nations. There were assembled nations from the Indus, from the Persian Gulf, the Red Sea, the Levant, the Ægean and the Euxine—Egyptian, Ethiopian, and Lybian. Forty-six nations were represented—all that were tributary to Persia. From the estimates made by Herodotus, there were one million seven hundred thousand foot, eighty thousand horse, besides a large number of chariots. With the men who manned the fleet and those he pressed into his service on the march, the aggregate of his forces was two million six hundred and forty thousand. Scarcely an inferior number attended the soldiers as slaves, sutlers, and
