moment when Heraclius was entering upon his long Persian struggle, Mahomet was yet prostrate, and his destiny was doubtful. Eleven years after, viz. in six hundred and thirty-three, the prophet was dead and gone; but his first successor was already in Syria as a conqueror. Such had been the velocity of events. The Persian war had then been finished by three years, but the exhaustion of the empire had perhaps, at that moment, reached its maximum. We are satisfied, that ten years' repose from this extreme state of collapse would have shown us another result. Even as it was, and caught at this enormous disadvantage, Heraclius taught the robbers to tremble, and would have exterminated them, if not baffled by two irremediable calamities, neither of them due to any act or neglect of his own. The first lay in the treason of his lieutenants. The governors of Damascus, of Aleppo, of Emesa, of Bostra, of Kinnisrin, all proved traitors. The root of this evil lay, probably, in the disorders following the Persian invasion, which had made it the perilous interest of the emperor to appoint great officers from amongst those who had a local influence. Such persons it might have been ruinous too suddenly to set aside, as, in the event, it proved ruinous to employ them. A dilemma of this kind, offering but a choice of evils, belonged to the nature of any Persian war; and that particular war was bequeathed to Heraclius by the management of his predecesors. But the second calamity was even more fatal; it lay in the composition of the Syrian population, and its original want of vital cohesion. For no purpose could this population be united: they formed a rope of sand. There was the distraction of religion (Jacobites, Nestorians, &c.); there was the distraction of races--slaves and masters, conquered and conquerors, modern intruders mixed, but not blended with, aboriginal mountaineers. Property became the one principle of choice between the two governments. Where was protection to be had for _that_? Barbarous as were the Arabs, they saw their present advantage. Often it would happen from the position of the armies, that they could, whilst the emperor could not, guarantee the instant security of land or of personal treasures; the Arabs could also promise, sometimes, a total immunity from taxes, very often a diminished scale of taxation, always a remission of arrears; none of which demands could be listened to by the emperor, partly on account of the public necessities, partly from jealousy of establishing operative precedents. For religion, again, protection was more easily obtained in that day from the Arab, who made war on Christianity, than from the Byzantine emperor, who was its champion. What were the different sects and subdivisions of Christianity to the barbarian? Monophysite, Monothelite, Eutychian, or Jacobite, all were to him as the scholastic disputes of noble and intellectual Europe to the camps of gypsies. The Arab felt
