with which Cæsar and Pompey had disputed the empire of the world. The Roman world was now contracted to a corner of Thrace, between the Propontis and the Black Sea, about fifty miles in length and thirty in breadth; a space of ground not more extensive than the lesser principalities of Germany or Italy, if the remains of Constantinople had not still represented the wealth and populousness of a kingdom. To restore the public peace, it was found necessary to divide this fragment of the empire; and while Palæologus and Manuel were left in possession of the capital, almost all that lay without the walls was ceded to the blind princes, who fixed their residence at Rhodosto and Selybria. In the tranquil slumber of royalty, the passions of John Palæologus survived his reason and his strength: he deprived his favorite and heir of a blooming princess of Trebizond; and while the feeble emperor labored to consummate his nuptials, Manuel, with a hundred of the noblest Greeks, was sent on a peremptory summons to the Ottoman porte. They served with honor in the wars of Bajazet; but a plan of fortifying Constantinople excited his jealousy: he threatened their lives; the new works were instantly demolished; and we shall bestow a praise, perhaps above the merit of Palæologus, if we impute this last humiliation as the cause of his death.

The earliest intelligence of that event was communicated to Manuel, who escaped with speed and secrecy from the palace of Boursa to the Byzantine throne. Bajazet affected a proud indifference at the loss of this valuable pledge; and while he pursued his conquests in Europe and Asia, he left the emperor to struggle with his blind cousin John of Selybria, who, in eight years of civil war, asserted his right of primogeniture. At length, the ambition of the victorious sultan pointed to the conquest of Constantinople; but he listened to the advice of his vizier, who represented that such an enterprise might unite the powers of Christendom in a second and more formidable crusade. His epistle to the emperor was conceived in these words: "By the divine clemency, our invincible cimeter has reduced to our obedience almost all Asia, with many and large countries in Europe, excepting only the city of Constantinople; for beyond the walls thou hast nothing left. Resign that city; stipulate thy reward; or tremble, for thyself and thy unhappy people, at the consequences of a rash refusal." But his ambassadors were instructed to soften their tone, and to propose a treaty, which was subscribed with submission and gratitude. A truce of ten years was purchased by an annual tribute of thirty thousand crowns of gold; the Greeks deplored the public toleration of the law of Mahomet, and Bajazet enjoyed the glory of establishing a Turkish cadhi, and founding a royal mosque in the metropolis of the Eastern church.²² Yet this truce was soon violated by the restless sultan: in the cause of the prince of Selybria, the lawful emperor, an army of Ottomans again threatened Constantinople; and the distress of Manuel implored the protection of the king of France. His plaintive embassy obtained much pity and some relief; and the conduct of the succor was intrusted to the marshal Boucicault,²³ whose religious chivalry was inflamed by the desire of revenging his captivity on the infidels. He sailed with four ships of war, from Aiguesmortes to the Hellespont; forced the passage, which was guarded by seventeen Turkish galleys; landed at Constantinople a supply of six hundred men-at-arms and sixteen hundred archers; and reviewed them in the adjacent plain, without condescending to number or array the multitude of Greeks. By his presence, the blockade was raised both by sea and land; the flying squadrons of Bajazet were driven to a more respectful distance; and several castles in Europe and Asia were stormed by the emperor and the marshal, who fought with equal valor by each other's side. But the Ottomans soon returned with an increase of numbers; and the intrepid Boucicault, after a year's struggle, resolved to evacuate a country which could no longer afford either pay or provisions for his soldiers. The marshal offered to conduct Manuel to the French court, where he might solicit in person a supply of men and money; and advised, in the mean while, that, to extinguish all domestic discord, he should leave his blind competitor on the throne. The proposal was embraced: the prince of Selybria was introduced to the capital; and such was the public misery, that the lot of the exile seemed more fortunate than that of the sovereign. Instead of applauding the success of his vassal, the Turkish sultan claimed the city as his own; and on the refusal of the emperor John, Constantinople was more closely pressed by the calamities of war and famine. Against such an enemy prayers and resistance were alike unavailing; and the savage would have devoured his prey, if, in the fatal moment, he had not been overthrown by another savage stronger than himself. By the victory of Timour or Tamerlane, the fall of Constantinople was delayed about fifty years; and this important, though accidental, service may justly introduce the life and character of the Mogul conqueror.
