Herodotus mentions an earthquake as occurring soon after this visit, and Thucydides another; and the story of the island having once floated about at large, before it became fixed, is doubtless connected with its volcanic origin. The Persian armament swept like a blight through the other islands, and soon appeared off the coast of Eubœa. Meeting with no resistance on landing, they disembarked their cavalry, and laid siege to Eretria, which was betrayed to them after six days of severe fighting. The town was burnt and sacked, and the inhabitants carried away captive. They expected from the threats of Darius the worst of fates; but when they reached Susa, that forgiving monarch settled them peaceably at a place called Ardericca, where there was a famous well which produced salt, bitumen, and petroleum. Herodotus saw them there, and mentions particularly that they had not forgotten their Greek.
The Athenians, after the fall of Eretria, must have felt much as the Jews did when Sennacherib appeared before their walls, and Rabshakeh boasted that all the kings and gods on his march had fallen before him. But when they heard that the Persians had actually disembarked at Marathon, they must have felt as England would have felt had the news come that Buonaparte had landed in Pevensey Bay, close to the ominous field of Hastings. For Marathon had not as yet become a synonym for Victory; on the contrary, Pisistratus had beaten the Athenian commons on that plain, and his son Hippias was now with the Persian host in a temper which, they might be sure, had not improved with old age, exile, and disappointment.
