Such is human greatness at the best, even were it ever so innocent; but as to this poor Sultan, there is another aspect even of his glorious deeds. If I have seemed here or elsewhere in these Lectures to speak of him or his with interest or admiration, only take me, Gentlemen, as giving the external view of the Turkish history, and that as introductory to the determination of its true significance. Historians and poets may celebrate the exploits of Malek; but what were they in the sight of Him who has said that whoso shall strike against His corner-stone shall be broken; but on whomsoever it shall fall, shall be ground to powder? Looking at this Sultan's deeds as mere exhibitions of human power, they were brilliant and marvellous; but there was another judgment of them formed in the West, and other feelings than admiration roused by them in the faith and the chivalry of Christendom. Especially was there one, the divinely appointed shepherd of the poor of Christ, the anxious steward of His Church, who from his high and ancient watch tower, in the fulness of apostolic charity, surveyed narrowly what was going on at thousands of miles from him, and with prophetic eye looked into the future age; and scarcely had that enemy, who was in the event so heavily to smite the Christian world, shown himself, when he gave warning of the danger, and prepared himself with measures for averting it. Scarcely had the Turk touched the shores of the Mediterranean and the Archipelago, when the Pope detected and denounced him before all Europe. The heroic Pontiff, St. Gregory the Seventh, was then upon the throne of the Apostle; and though he was engaged in one of the severest conflicts which Pope has ever sustained, not only against the secular power, but against bad bishops and priests, yet at a time when his very life was not his own, and present responsibilities so urged him, that one would fancy he had time for no other thought, Gregory was able to turn his mind to the consideration of a contingent danger in the almost fabulous East. In a letter written during the reign of Malek Shah, he suggested the idea of a crusade against the misbeliever, which later popes carried out. He assures the Emperor of Germany, whom he was addressing, that he had 50,000 troops ready for the holy war, whom he would fain have led in person. This was in the year 1074.
