The ancient cultures of Egypt, Greece, and Rome were evidently the product of geographical opportunity and economic and political development rather than of racial constitution, and much of their civilization had an Oriental source.14 Greece took its arts and letters from Asia Minor, Crete, Phoenicia, and Egypt. In the second millennium B.C. Greek culture was “Mycenaean,” partly derived from Crete, which had probably learned from Asia Minor. When the “Nordic” Dorians came down through the Balkans, toward 1100 B.C., they destroyed much of this proto-Greek culture; and only after an interval of several centuries did the historic Greek civilization emerge in the Sparta of “Lycurgus,” the Miletus of Thales, the Ephesus of Heracleitus, the Lesbos of Sappho, the Athens of Solon. From the sixth century B.C. onward the Greeks spread their culture along the Mediterranean at Durazzo, Taranto, Crotona, Reggio Calabria, Syracuse, Naples, Nice, Monaco, Marseilles, Málaga. From the Greek cities of south Italy, and from the probably Asiatic culture of Etruria, came the civilization of ancient Rome; from Rome came the civilization of Western Europe; from Western Europe came the civilization of North and South America. In the third and following centuries of our era various Celtic, Teutonic, or Asiatic tribes laid Italy waste and destroyed the classic cultures. The South creates the civilizations, the North conquers them, ruins them, borrows from them, spreads them: this is one summary of history.
