“The first horde were the Seljukians, who invaded the Eastern empire about the middle of the eleventh century, under Togrul Beg. He suddenly overran, with myriads of cavalry, the frontier, from Taurus to Arzeroum, and spread it with blood and devastation. Alp Arslan, his successor, soon renewed the invasion, conquered Armenia and Georgia, penetrated into Cappadocia and Phrygia, and scattered detachments over the whole of lesser Asia. His troops being subsequently driven back, he renewed the war, and recovered those provinces. His descendants, and others of the race, soon after extended their conquests, and established the kingdoms in the east of Persia and Syria, and Roum, in lesser Asia, which they maintained through many generations, and made their sway a scorpion scourge to the idolatrous inhabitants. The Christians were allowed the exercise of their religion on the conditions of tribute and servitude, but were compelled to endure the scorn of the victors, to submit to the abuse of their priests and bishops, and to witness the apostasy of their brethren, the compulsory circumcision of many thousands of their children, and the subjection of many thousands to a debasing and hopeless slavery. “The second army was that of the Moguls, who, in the thirteenth century, after the conquest of Persia, passed the Euphrates, plundered and devastated Syria, subdued Armenia, Iconium, and Anatolia, and extinguished the Seljukian dynasty. Another army advancing to the west, devastated the country on both sides of the Danube, Thrace, Bulgaria, Servia, Bosnia, Hungary, Austria, and spread them with the ruins of their cities and churches, and the bones of their inhabitants. This horde had been prepared for this invasion by vast conquests in the East. “The third were the Ottomans, who in the beginning of the fourteenth century conquered Bithynia, Lydia, Ionia, Thrace, Bulgaria, Servia, and in the following century Constantinople itself, and have maintained their empire to the present time. They were released from restraint on the one hand by the decay of the Mogul Khans, to whom they had been subject, and on the other by the dissensions and weakness of the Greeks. “The last was that of the Moguls under Tamerlane, who in the beginning of the fifteenth century overran Georgia, Syria, and Anatolia, and spread them with slaughter and desolation. He also had been prepared for this incursion by his previous victories and conquests.”—_Ex. Apoc._, pp. 225, 226. These armies, the number of which is literally “myriads of myriads,” were not all subsequent to the time when they had power to subject the Eastern Roman empire; but may be the four, from the fact that the Mohammedan power was extended by these armies, which till this time had been restrained from accomplishing the subjugation of Constantinople.
