The idea of an unknown sect from an Arabian desert attacking the power of the "Great King" seemed preposterous to those who heard, for Persia was then at the height of one of her spasmodic periods of success. Some eighteen years before the envoy of Islam appeared at his court the king had covered his empire with glory by the capture of Jerusalem (611 A.D.), then in the hands of Rome, and inhabited chiefly by Christians. On this occasion the Jews throughout Palestine rose on his behalf with the object of exterminating the Christians, ninety {35} thousand of whom are said to have perished. "Every Christian church was demolished, that of the Holy Sepulchre was the object of furious hatred; the stately building of Helena and Constantine was abandoned to the flames; the devout offerings of three hundred years were rifled in one sacrilegious day."[1] Fortunately for future ages, the great church, built by the pious Helena over the place where the body of Christ had lain, was not entirely destroyed; but--a worse blow still to the Christian inhabitants--the True Cross was taken from its sacred hiding place and carried Into Persia.

Egypt had also fallen into the hands of the conquering Khosru, when at length Heraclius, the Emperor of the East, "slumbering on the throne of Constantinople," awoke, drove the Persian from Syria and Egypt, restored the ruined churches of Jerusalem, and brought back in triumph the Cross to the Holy City. The preceding year had seen the fall of Khosru, and peace concluded between the Empires of Rome and Persia; eight years later Jerusalem was in the hands of the Saracens (637 A.D.). The years intervening between this event and the death of Mohammed had been utilised by the sons of Islam in making a series of conquests, which seem well-nigh miraculous. We can indeed only account for them by the fact that the contest was between a race of fighters, stirred by their new faith to a perfect frenzy of enthusiasm, and the remnants of Empires far gone in decay. Yet, even so, there was no light task. Chaldaea and Babylonia, perhaps the most ancient empires in the world, fell before the sword of Islam only after a long {36} and terrible struggle. The bloodshed on both sides was appalling, but the ever-increasing numbers of Moslems were always providing fresh recruits, eager to win victory or Paradise. Even when they were less numerous than their enemies, they more than made up for it by the determination and obstinacy of their attacks. Emboldened by this success, the Saracens flung themselves upon the Empire of Persia. Three months after the great battle of Cadesia, the "white palace" of Khosru was in their hands, and the remnants of the Persian hosts had fled before them.
