This marvellous work, produced more than a thousand years before there was a Germany, or an England, and almost a thousand before there was a Roman Empire, is still the world's great masterpiece, and is to-day an indispensable part of education. At the close of the "Heroic Age" something happened, which had the same effect upon Ancient Greece that many centuries later the descent of the Goths and Vandals had upon Southern Europe. Greece, too, had its northern barbarians. Some stronger and fiercer Aryan tribes poured down from Epirus, and for a time upset everything, just as the Goths did in Europe. The Dorians, a stern, unrelenting tribe, took possession of the southern extremity of the peninsula, called the Peloponnesus; and the city of Sparta was the head of their State. There were other States, too, in Greece, and each had its king and separate government. But although jealous of each other and almost always at war, they worshipped the same deities, consulted the same Oracles, and all alike gloried in being descended from the same gods and in being Greeks. The two most powerful States (or cities, which meant the same thing) were Athens and Sparta. But they were as widely separated in character and habits as if they did not belong to the same family. Athens was the brain, and Sparta the rough, strong arm of Greece. Athens delighted in poetry, music, art, and eloquence. The Spartans despised all these things. They scorned to use three words where two would do, and aimed only to make their youth fearless and terrible defenders of Greece. When a child was born, if it did not give promise of being physically strong and perfect, it was cast into a ravine and then left to perish. When the boys who were permitted to live were seven years old, they were taken from their mothers and made to endure cold, hunger, and inhuman severities. They were beaten until the blood flowed, simply to teach them endurance, and a Spartan boy would die under the lash rather than endure the disgrace of uttering a cry of pain. There was never any family life, nor pleasure. Every boy was trained to be a soldier; and until he was sixty years old the man belonged to the State absolutely. And all those years he ate his black broth at a public mess, seasoned only with fatigue and hunger. A witty Athenian said he did not wonder the Spartans were brave in battle, for death was preferable to their life. The severe code of laws by which they were governed was established by Lycurgus, about 770 B.C. (before Christ).
