When the child was four years old he had to be hurried away from his home and then from his country. The Persians were coming. The awful words lost none of their terror from the fact that in Greek the word "Persai," Persians, meant "to destroy." So later it added something to the dread inspired by Rome that her name, "Roma," meant "strength." The family must have crossed the narrow seas to Salamis or further, and seen the smoke of the Persian conflagrations rising daily from new towns and villages of Attica and at last from the Acropolis, or Citadel, itself. Then came the enormous desperate sea-battle; the incredible victory; the sight of the broken oriental fleet beating sullenly away for Asia and safety, and the solemn exclamation of the Athenian general, Themistocles, "It is not we who have done this!" The next year the Athenians could return to Attica and begin to build up their ruined farms. Then came the final defeat of the Persian land army at Plataea, and the whole atmosphere lifted. Athens felt that she had acted like a hero and was reaping a hero's reward. She had borne the full brunt of the war; she had voluntarily put herself under the orders of Sparta rather than risk a split in the Greek forces; and now she had come out as the undisputed mistress of the sea, the obvious champion round whom the eastern Greeks must rally. Sparta, not interested in matters outside her own borders, and not capable of any constructive policy, dropped sulkily out, and left her to carry on the offensive war for the liberation of the Greeks in Asia. The current of things was with her.
