The hopes which the Greek cities might have built upon the rebellion of the Lydians were quickly broken. The mother country had refused any help. Sparta would not come to their assistance, and Athens, torn as she was by internal dissensions, could not. No one in the cantons of the Greek peninsula roused themselves to give aid to an important section of the Greek nation, to the colonies which had outstripped the mother country in their development, or strove to save the most vigorous centres of Greek nationality from subjection to a foreign people, which had come out of the remote part of Asia. If the voice of a common blood and the sense of nationality failed to warn the Greeks beyond the sea against giving over to strangers for plunder such rich and flourishing cities, was there no one in Hellas who foresaw that if the establishment of the Persian dominion on the coasts of Asia Minor were not prevented, and the cities of the coast with their navy were allowed to fall into the hands of the Persians, Greece itself would not be safe from their attack, and they would be able to visit the coasts of Hellas in Greek ships? Yet even without assistance the power of the Hellenic cities would have sufficed for a considerable resistance to the Persians--for the position of affairs in Asia did not allow Cyrus to bring any great force against these distant coasts--if they had been able to understand and take to heart the lessons of their own past. If they had neglected to unite their forces against the Lydians, such union was now doubly necessary. They had learned from experience the evil of delay, and the danger was now greater than ever. The Greek cities were in uncontested possession of the sea,[37] and thus in a position to give help in common to any city which the Persians might attack. An organisation which permitted the whole force of the city to be used for the benefit of each one, would have given a prospect of successful resistance. But no step whatever was taken in this direction. Each city turned its attention to strengthening its own walls, and awaiting the attack of the Persians.
