"If the army of Nicias had not been defeated under the walls of Syracuse; if the Athenians had, acquiring Sicily, held the balance between Rome and Carthage, sent garrisons to the Greek colonies in the south of Italy, Rome might have been all that its intellectual condition entitled it to be, a tributary, not the conqueror, of Greece; the Macedonian power would never have attained to the dictatorship of the civilized states of the world." Such is the exclamation of Shelley over the fall of Athens. But, according to the Greek proverb, to desire impossibilities--in the past as in the present--is a sickness of the soul. No Greek state could have maintained its #êthos# while it ruled a foreign empire; nor is the right to govern measured by merely intellectual capacity. The work of Greece was essentially spiritual and not political. The chief sign of weakness which meets us in the fourth period is in the region of politics. After the humiliation of Athens, Sparta assumed the leadership of Greece. But she shamefully misused her power by betraying the Greek cities of Asia to the Persians, while her generals and harmosts made use of their authority for the indulgence of their private vices. Nothing in the previous training of the Spartan race fitted them for the control of nations with whose more liberal institutions and refined manners they could not sympathize. Their tyranny proved insupportable, and was at last reduced to the dust by the Thebans under Pelopidas and Epaminondas. But Thebes had neither the wealth nor the vigor to administer the government of Hellas. Therefore the Greek states fell into a chaos of discord, without leadership, without a generous spirit of mutual confidence and aid; while at the same time the power of the Macedonian kingdom was rapidly increasing under the control of Philip. An occasion offered itself to Philip for interfering in the Greek affairs. From that moment forward forever the cities of Greece became the fiefs of foreign despots. The occasion in question was a great one. The Phocians had plundered the Delphian temple, and none of the Greeks were strong enough to punish them. The act of the Phocians was parricidal in its sacrilege, suicidal in short-sightedness. Defiling the altar of the ancestral god, on whose oracles the states had hitherto depended for counsel, and destroying, with the sanctity of Delphi, the sacred symbol of Greek national existence, they abandoned themselves to desecration and dishonor. With as little impunity could a king of Judah have robbed the temple and invaded the holiest of holies. But neither Spartans nor Athenians nor yet Thebans arose to avenge the affront offered to their common nationality. The whole of Greece proper lay paralyzed, and the foreigner stepped in--Philip, whom in their pride they had hitherto called the Barbarian. He took up the cause of Phoebus and punished the children of the Delphian god for their impiety. It was clearly
