The epics showed the Greeks a barbaric people without iron, without writing, and still not living in cities. They seem to have lived at first in open villages of huts around the halls of their chiefs outside the ruins of the Ægean cities they had destroyed. Then they began to wall their cities and to adopt the idea of temples from the people they had conquered. It has been said that the cities of the primitive civilizations grew up about the altar of some tribal god, and that the wall was added; in the cities of the Greeks the wall preceded the temple. They began to trade and send out colonies. By the seventh century B.C. a new series of cities had grown up in the valleys and islands of Greece, forgetful of the Ægean cities and civilization that had preceded them; Athens, Sparta, Corinth, Thebes, Samos, Miletus among the chief. There were already Greek settlements along the coast of the Black Sea and in Italy and Sicily. The heel and toe of Italy was called Magna Græcia. Marseilles was a Greek town established on the site of an earlier Phœnician colony. Now countries which are great plains or which have as a chief means of transport some great river like the Euphrates or Nile tend to become united under some common rule. The cities of Egypt and the cities of Sumeria, for example, ran together under one system of government. But the Greek peoples were cut up among islands and mountain valleys; both Greece and Magna Græcia are very mountainous; and the tendency was all the other way. When the Greeks come into history they are divided up into a number of little states which showed no signs of coalescence. They are different even in race. Some consist chiefly of citizens of this or that Greek tribe, Ionic, Æolian or Doric; some have a mingled population of Greeks and descendants of the pre-Greek “Mediterranean” folk; some have an unmixed free citizenship of Greeks lording it over an enslaved conquered population like the “Helots” in Sparta. In some the old leaderly Aryan families have become a close aristocracy; in some there is a democracy of all the Aryan citizens; in some there are elected or even hereditary kings, in some usurpers or tyrants.
