But far more favorable, not only for a beginning of civilization but for a high state of development, was the territory occupied by the Grecian tribes. Shut in from the north by a mountain range, surrounded on every other side by the sea, a fertile and well-watered land, of mild climate, it was protected {143} from the encroachments of "barbarians." The influence of geographical contour is strongly marked in the development of the separate states of Greece. The small groups that settled down on a family basis were separated from each other by ranges of hills, causing each community to develop its own characteristic life. These communities had a common language, differing somewhat in dialect, and the foundation of a common religion, but there never could exist sufficient similarity of character or unity of sentiment to permit them to unite into a strong central nation. A variety of life is evinced everywhere. Those who came in contact with the ocean differed from those who dwelt in the interior, shut in by the mountains. The contact with the sea gives breadth of thought, largeness of life, while those who are enclosed by mountains lead a narrow life, intense in thought and feeling. Without the protection of nature, the Grecian states probably would never have developed the high state of civilization which they reached. Rome presents a similar example. It is true that the Italian tribes that entered the peninsula had considerable force of character and thorough development as they were about to enter upon a period of civilization. Like the Greeks, the discipline of their early Aryan ancestors had given them much of strength and character. Yet the favorable location of Italy, bounded on the north by a high mountain range and enclosed by the sea, gave abundant opportunity for the national germs to thrive and grow. Left thus to themselves, dwelling under the protection of the snow-capped Alps, and surrounded by the beneficent sea, national life expanded, government and law developed and thrived, and the arts of civilized life were practised. The national greatness of the Romans may in part be attributed to the period of repose in which they pursued unmolested the arts of peace before their era of conquest began. Among the mountains of Switzerland are people who claim never to have been conquered. In the wild rush of the {144} barbarian hordes into the Roman Empire they were not overrun. They retain to this day their early sentiments of liberty; their greatness is in freedom and equality. The mountains alone protected them from the assaults of the enemy and the crush of moving tribes.
