The Persians were quick to learn, and gladly appropriated to themselves the civilization of Nineveh and Babylon; but luxury and dissipation will unnerve the strongest empire, and after a time the designing beauties of the harem became the rulers of weak and wicked princes, and though Persian magnificence lasted from Darius to the last Persian king, their final failure was due to their own corruption as much as to the forces of Alexander the Great. The Īrānian mind seemed to be the harbinger of progress, in the simplicity of its beginnings, in its striving for the noble, the manly, and the true, but the selfishness of the later Persian kings developed not only into luxury, but also into dissipation: reclining on couches with golden feet, drinking the wines[13] of Helbon and Shīrāz, they yielded to no rule except their own pleasure—there was no precept of morality that they could not violate at will, no law in their legal code that involved the recognition of the rights of other nations; and this intense self-worship prepared the way for the coming conqueror. The government of Persia became what the government of Turkey now is—a highly centralized bureaucracy, the members of which owed their offices to an irresponsible despot; the people of Persia therefore hailed Alexander as their deliverer from disintegration and decay. PHYSICAL FEATURES OF PERSIA. “The Land of the Lion and the Sun,” presents the strongest physical contrasts; with the king of the forest and the king of day emblazoned upon her banners, she extended her dominion over rocky steppes and barren sands, as well as fertile fields and stately forests. Persia proper was a comparatively small province, but the tide of conquest gathered many nations beneath her banners, and the dominion of Cyrus extended from the Mediterranean to the Indus, and from the snowy peaks of the Caucasus, downward to the shores of the Persian Gulf and the Arabian Sea. The court of Darius was enriched by tributes from Egypt and Babylonia, from Assyria and India, from Media, Lydia, Phœnicia and many other lands. Modern Persia occupies the larger portion of the great Īrānian plateau, which rises to the height of from four to eight thousand feet, between the valleys of the Indus and the Tigris, and covers more than a million square miles. On the northwest the Persian Empire is united to the mountains of Asia Minor by the high lands of Armenia, while on the northeast the Paropansius and the Hindū Kush connect it with the Himālayas of ancient India. The eastern and western boundaries are traced with more or less uncertainty, amidst high ranges of mountains broken here and there by deserts and valleys. The fertile lowlands are found in the forest-clad regions south of the Caspian Sea, and down toward the shore of the Persian Gulf.
