The Greeks and the Turks passed an anxious and sleepless winter: the former were kept awake by their fears, the latter by their hopes; both by the preparations of defence and attack; and the two emperors, who had the most to lose or to gain, were the most deeply affected by the national sentiment. In Mahomet, that sentiment was inflamed by the ardor of his youth and temper: he amused his leisure with building at Adrianople²⁴ the lofty palace of Jehan Numa, (the watchtower of the world;) but his serious thoughts were irrevocably bent on the conquest of the city of Cæsar. At the dead of night, about the second watch, he started from his bed, and commanded the instant attendance of his prime vizier. The message, the hour, the prince, and his own situation, alarmed the guilty conscience of Calil Basha; who had possessed the confidence, and advised the restoration, of Amurath. On the accession of the son, the vizier was confirmed in his office and the appearances of favor; but the veteran statesman was not insensible that he trod on a thin and slippery ice, which might break under his footsteps, and plunge him in the abyss. His friendship for the Christians, which might be innocent under the late reign, had stigmatized him with the name of Gabour Ortachi, or foster-brother of the infidels;²⁵ and his avarice entertained a venal and treasonable correspondence, which was detected and punished after the conclusion of the war. On receiving the royal mandate, he embraced, perhaps for the last time, his wife and children; filled a cup with pieces of gold, hastened to the palace, adored the sultan, and offered, according to the Oriental custom, the slight tribute of his duty and gratitude.²⁶ "It is not my wish," said Mahomet, "to resume my gifts, but rather to heap and multiply them on thy head. In my turn, I ask a present far more valuable and important; -- Constantinople." As soon as the vizier had recovered from his surprise, "The same God," said he, "who has already given thee so large a portion of the Roman empire, will not deny the remnant, and the capital. His providence, and thy power, assure thy success; and myself, with the rest of thy faithful slaves, will sacrifice our lives and fortunes." -- "Lala,"²⁷ (or preceptor,) continued the sultan, "do you see this pillow? All the night, in my agitation, I have pulled it on one side and the other; I have risen from my bed, again have I lain down; yet sleep has not visited these weary eyes. Beware of the gold and silver of the Romans: in arms we are superior; and with the aid of God, and the prayers of the prophet, we shall speedily become masters of Constantinople." To sound the disposition of his soldiers, he often wandered through the streets alone, and in disguise; and it was fatal to discover the sultan, when he wished to escape from the vulgar eye. His hours were spent in delineating the plan of the hostile city; in debating with his generals and engineers, on what spot he should erect his batteries; on which side he should assault the walls; where he should spring his mines; to what place he should apply his scaling- ladders: and the exercises of the day repeated and proved the lucubrations of the night.
