It was just the same with the ruling nation, the Persians, however vigorous their entrance into history under Cyrus. The Persian kingdom is, indeed, a civilised state, but the civilisations that it includes lack the highest that a civilisation can offer: an energetic, independent life, a combination of the firm institutions and permanent attainments of the past with the free, progressive, and creative movement of individuality. So the East, after the Persian period, was unable of its own force to create anything new. It stagnated, and, had it not received new elements from without, had it been left permanently to itself, would perhaps in the course of centuries have altered its external form again and again, but would hardly have produced anything new or have progressed a step beyond what had already been attained. But when Cyrus and Darius founded the Persian kingdom, the East no longer stood alone. The nations and kingdoms of the East came into communication with the coast of the Mediterranean very early--not later than the beginning of the second millennium B.C.; and under their influence, about 1500 B.C., a civilisation arose among the Greeks bordering the Ægean. We call it the Mycenæan, and in spite of its formal dependence upon the East it could, in the field of art (where alone we have an exact knowledge of it), take an independent and equal place beside the great civilisations of the East. How Greek civilisation continued to advance from step to step for many centuries in the field of politics and society as well as in that of the intellect; how it spread simultaneously over all the islands and coasts of the Mediterranean, from Massalia on the coast of the Ligurians and Cumæ in the land of the Oscans to the Crimea and the eastern coast of the Black Sea, and in the south as far as Cyprus and Cilicia; how Greek culture at the same time took root in much more remote districts, especially in Asia Minor; and how under its influence an energetic civilisation arose among the tribes of Italy, cannot be depicted here. When the Persian kingdom was founded the Hellenes had developed from a group of linguistically related tribes into a nation possessing a completely independent culture whose equal the world had never yet seen, a culture whose mainspring was that very political and intellectual freedom of the individual which was completely lacking in the East.
