Thus Persia never lost wholly its ancient prestige, and still remains, after the rise and fall of so many dynasties, and such great vicissitudes from Greek and Arab conquests, a powerful country twice the size of Germany, under the rule of an independent prince. There seems no likelihood of her ever again playing so grand a part in the world's history as when, under the great Cyrus, she prepared the transfer of empire from the Orient to the Occident. But "what has been, has been, and she has had her hour." AUTHORITIES. Herodotus and Xenophon are our main authorities, though not to be fully relied upon. Of modern works Rawlinson's Ancient Monarchies and Rawlinson's Herodotus are the most valuable. Ragozin has written interesting books on Media, Persia, Assyria, and Chaldaea, making special note of the researches of European travellers in the East. Fergusson, Layard, Sayce, and George Smith have shed light on all this ancient region. Johnson's work is learned but indefinite. Benjamin is the latest writer on the history of Persia; but a satisfactory life of Cyrus has yet to be written. JULIUS CAESAR. * * * * * 100-44 B.C. IMPERIALISM. The most august name in the history of the old Roman world, and perhaps of all antiquity, is that of Julius Caesar; and a new interest has of late been created in this extraordinary man by the brilliant sketch of his life and character by Mr. Froude, who has whitewashed him, as is the fashion with hero-worshippers, like Carlyle in his history of Frederick II. But it is not an easy thing to reverse the verdict of the civilized world for two thousand years, although a man of genius can say many interesting things and offer valuable suggestions. In his Life of Caesar Mr. Froude seems to vindicate Imperialism, not merely as a great necessity in the corrupt times which succeeded the civil wars of Marius and Sulla, but as a good thing in itself. It seems to me that while there was a general tendency to Imperialism in the Roman world for one or two hundred years before Christ, the whole tendency of modern governments is against it, and has been since the second English Revolution. It still exists in Russia and Turkey, possibly in Germany and Austria; yet constitutional forms of government seem to be gradually taking its place. What a change in England, France, Italy, and Spain during the last hundred years!--what a breaking up of the old absolutism of the Bourbons! Even the imperialism of Napoleon is held in detestation by a large class of the French nation.
