The Seven Great Monarchies of the Ancient Eastern World, Vol 7. (of 7): The Sassanian the History, Geography and Antiquities of Chaldaea, Assyria, Babylon, ... Parthia and Sassanian or New Persian Empire

When the great Empire of the Persians, founded by Cyrus, collapsed under the attack of Alexander the Great, the dominant race of Western Asia did not feel itself at the first reduced to an intolerable condition. It was the benevolent design of Alexander to fuse into one the two leading peoples of Europe and Asia, and to establish himself at the head of a Perso-Hellenic State, the capital of which was to have been Babylon. Had this idea been carried out, the Persians would, it is evident, have lost but little by their subjugation. Placed on a par with the Greeks, united with them in marriage bonds, and equally favored by their common ruler, they could scarcely have uttered a murmur, or have been seriously discontented with their position. But when the successors of the great Macedonian, unable to rise to the height of his grand conception, took lower ground, and, giving up the idea of a fusion, fell back upon the ordinary status, and proceeded to enact the ordinary role, of conquerors, the feelings of the late lords of Asia, the countrymen of Cyrus and Darius, must have undergone a complete change.
