The annexation of Asia Minor to the empire of Cyrus was followed by a protracted war with the barbarians on his eastern boundaries. The imperfect subjugation of barbaric nations living in Central Asia occupied Cyrus, it is thought, about twelve years. He pushed his conquests to the Iaxartes on the north and Afghanistan on the east, reducing that vast country which lies between the Caspian Sea and the deserts of Tartary.

Cyrus was advancing in years before he undertook the conquest of Babylon, the most important of all his undertakings, and for which his other conquests were preparatory. At the age of sixty, Cyrus, 538 B.C., advanced against Narbonadius, the proud king of Babylon,--the only remaining power in Asia that was still formidable. The Babylonian Empire, which had arisen on the ruins of the Assyrian, had lasted only about one hundred years. Yet what wonders and triumphs had been seen at Babylon during that single century! What progress had been made in arts and sciences! What grand palaces and temples had been erected! What a multitude of captives had added to the pomp and wealth of the proudest city of antiquity! Babylon the great,---"the glory of kingdoms," "the praise of the whole earth," the centre of all that was civilized and all that was corrupting in the Oriental world, with its soothsayers, its magicians, its necromancers, its priests, its nobles,--was now to fall, for its abominations cried aloud to heaven for punishment.

This great city was built on both sides of the Euphrates, was fifteen miles square, with gardens and fields capable of supporting a large population, and was stocked with provisions to maintain a siege of indefinite length against any enemy. The accounts of its walls and fortifications exceed belief, estimated by Herodotus to be three hundred and fifty feet in height, with a wide moat surrounding them, which could not be bridged or crossed by an invading army. The soldiers of Narbonadius looked with derision on the veteran forces of Cyrus, although they were inured to the hardships and privations of incessant war. To all appearance the city was impregnable, and could be taken only by unusual methods. But the genius of the Persian conqueror, according to traditional accounts, surmounted all difficulties. Who else would have thought of diverting the Euphrates from its bed into the canals and gigantic reservoirs which Nebuchadnezzar had built for purposes of irrigation? Yet this seems to have been done. Taking advantage of a festival, when the whole population were given over to bacchanalian orgies, and therefore off their guard, Cyrus advanced, under the cover of a dark night, by the bed of the river, now dry, and easily surprised the drunken city, slaying the king, with a thousand of his lords, as he was banqueting in his palace. The slightest accident or miscarriage would have defeated so bold an operation. The success of Cyrus had all the mystery and solemnity of a Providential event. Though no miracle was wrought, the fall of Babylon--so strong, so proud, so defiant--was as wonderful as the passage of the Israelites across the Red Sea, or the crumbling walls of Jericho before the blasts of the trumpets of Joshua.

However, this account is to be taken with some reserve, since by the discoveries of historical "cylinders,"--the clay books whereon the Chaldaean priests and scribes recorded the main facts of the reigns of their monarchs,--and especially one called the "Proclamation Cylinder," prepared for Cyrus after the fall of Babylon, it would seem that dissension and treachery within had much to do with facilitating the entrance of the invader. Narbonadius, the second successor of Nebuchadnezzar, had quarrelled with the priesthood of Babylon, and neglected the worship of Bel-Marduk and Nebo, the special patron gods of that city. The captive Jews also, who had been now nearly fifty years in the land, had grown more zealous for their own God and religion, more influential and wealthy, and even had become in some sort a power in the State. The invasion of Cyrus--a monotheist like themselves--must have seemed to them a special providence from Jehovah; indeed, we know that it did, from the records in II. Chronicles xxxvi. 22, 23: "The Lord stirred up the spirit of Koresh, King of Persia, that he made a proclamation throughout all his kingdom, and put it also in writing." The same words occur in the beginning of the Book of Ezra, both referring to the sending home of the Jews after the fall of Babylon; the forty-sixth chapter of Isaiah also: "The Lord saith of Koresh, He is my shepherd, and shall perform all my pleasure."

Babylon was not at that time levelled with the ground, but became one of the capitals of the Persian Empire, where the Persian monarch resided for more than half the year. Although the Babylonian Empire began with Nabopolassar, B.C. 625, on the destruction of Nineveh, yet Babylon was a very ancient city and the capital of the ancient Chaldaean monarchy, which lasted under various dynasties from about 2400 B.C. to 1300 B.C., when it was taken by the Assyrians under Tig Vathi-Nin. The great Assyrian Empire, which thus absorbed ancient Babylonia, lasted between six and seven hundred years, according to Herodotus, although recent discoveries and inscriptions make its continuance much longer, and was the dominant power of Asia during the most interesting period of Jewish history, until taken by Cyaxares the Median. The limits of the empire varied at different times, for the conquered States which composed it were held together by a precarious tenure. But even in its greatest strength it was inferior in size and power to the Empire of Cyrus. To check rebellion,--a source of constant trouble and weakness,--the warlike monarchs were obliged to reconquer, imposing not only tribute and fealty, but overrunning the rebellious countries with fire and sword, and carrying away captive to distant cities a large part of the population as slaves. Thus at one time two hundred thousand Jews were transported to Assyria, and the "Ten Tribes" were scattered over the Eastern world, never more to return to Palestine.

On the rebellion of Nabopolassar, in 625 B.C., Babylon recovered not only its ancient independence, but more than its ancient prestige; yet the empire of which it was the capital lasted only about the same length of time as Media and Lydia,--the most powerful monarchies existing when Cyrus was born. Babylon, however, during its brief dominion, after having been subject to Assyria for seven hundred years, reappeared in unparalleled splendor, and was probably the most magnificent capital the ancient world ever saw until Rome arose. Even after its occupancy by the Persian monarchs for two hundred years, it called out the admiration of Herodotus and Alexander alike. Its arts, its sciences, its manufactures, to say nothing of its palaces and temples, were the admiration of travellers. When the proud conqueror of Palestine beheld the magnificence he had created, little did he dream that "this great Babylon which he had built" would become such a desolation that its very site would be uncertain,--a habitation for dragons, a dreary waste for owls and goats and wild beasts to occupy.

We should naturally suppose that Cyrus, with the kings of Asia prostrate before his satraps, would have been contented to enjoy the fruits of his labors; but there is no limit to man's ambition. Like Alexander, he sought for new worlds to conquer, and perished, as some historians maintain, in an unsuccessful war with some unknown barbarians on the northeastern boundaries of his empire,--even as Caesar meditated a war with the Parthians, where he might have perished, as Crassus did. Unbounded as is human ambition, there is a limit to human aggrandizement. Great conquerors are raised up by Providence to accomplish certain results for civilization, and when these are attained, when their mission is ended, they often pass away ingloriously,--assassinated or defeated or destroyed by self-indulgence, as the case may be. It seems to have been the mission
