he must have been impressed as deeply as Napoleon was in this century, that the elements had leagued themselves with his mortal enemies. After his flight, and the withdrawal of his fleet from the war, the Persians had not a chance left, and the defeat of his lieutenant Mardonius, at Plataea, was of the nature of a foregone conclusion. It is not possible to exaggerate the importance of the assistance which the Greeks received from the storms mentioned, and it is not strange that they were lavish in their thanks and offerings to Poseidon the Saviour, or that they continued piously to express their gratitude in later days. Mankind at large have reason to be thankful for the occurrence of those storms; for if they had not happened, Greece must have been conquered, and all that she has been to the world would have been that world's loss. It was not until after the overthrow of the Persians that Athens became the home of science, literature, art, and commerce; and if Athens had been removed from Greece, there would have been little of Hellenic genius left for the delight of future days. Not only was most of that which is known as Greek literature the production of the years that followed the failure of Xerxes, but the success of the Greeks was the means of preserving all of their earlier literature. The Persians were not barbarians, and, had they achieved their purpose, they might have promoted civilisation in Europe; but that civilization would have been Asiatic in its character, and it might have been as fleeting as the labors of the Carthaginians in Europe and Africa. Nor would they have felt any interest in the preservation of the works of those Greeks who wrote before the Marathonian time, which they would have regarded with that contempt with which most conquerors look upon the labors of those whom they have enslaved. That most brilliant of ages, the age of Pericles, could never have come to pass under the dominion of Persia; and the Greeks of Europe, when ruled by satraps from Susa, would have been of as little weight in the ancient world as, under that kind of rule, were the Greeks of Ionia. All future history was involved in the decision of the Persian contest, and we may well feel grateful that the event was not left for the hands of men to decide, but that the winds and the waves of the Grecian seas so far equalized the power of the combatants as to enable the Greeks, who fought for us as well as for themselves, to roll back the tide of Oriental conquest. We might not have had even the Secession War, if there had been no storms in the Thracian seas in a summer the roses of which perished more than two thousand three hundred years ago.[A]
