institution, they possessed a decisive superiority in war; since a regular body of infantry, in constant exercise and pay, was not maintained by any of the princes of Christendom. The Janizaries fought with the zeal of proselytes against their _idolatrous_ countrymen; and in the battle of Cossova, the league and independence of the Sclavonian tribes was finally crushed. As the conqueror walked over the field, he observed that the greatest part of the slain consisted of beardless youths; and listened to the flattering reply of his vizier, that age and wisdom would have taught them not to oppose his irresistible arms. But the sword of his Janizaries could not defend him from the dagger of despair; a Servian soldier started from the crowd of dead bodies, and Amurath was pierced in the belly with a mortal wound. [542] The grandson of Othman was mild in his temper, modest in his apparel, and a lover of learning and virtue; but the Moslems were scandalized at his absence from public worship; and he was corrected by the firmness of the mufti, who dared to reject his testimony in a civil cause: a mixture of servitude and freedom not unfrequent in Oriental history.

George Phranza, Michael Ducas, and Laonicus Chalcondyles, all three wrote after the taking of Constantinople.] [Footnote 53: See Cantemir, p. 37--41, with his own large and curious annotations.] [Footnote 54: _White_ and _black_ face are common and proverbial expressions of praise and reproach in the Turkish language. Hic _niger_ est, hunc tu Romane caveto, was likewise a Latin sentence.] [Footnote 541: According to Von Hammer. vol. i. p. 90, Gibbon and the European writers assign too late a date to this enrolment of the Janizaries. It took place not in the reign of Amurath, but in that of his predecessor Orchan.--M.] [Footnote 542: Ducas has related this as a deliberate act of self-devotion on the part of a Servian noble who pretended to desert, and stabbed Amurath during a conference which he had requested. The Italian translator of Ducas, published by Bekker in the new edition of the Byzantines, has still further heightened the romance. See likewise in Von Hammer (Osmanische Geschichte, vol. i. p. 138) the popular Servian account, which resembles that of Ducas, and may have been the source of that of his Italian translator. The Turkish account agrees more nearly with Gibbon; but the Servian, (Milosch Kohilovisch) while he lay among the heap of the dead, pretended to have some secret to impart to Amurath, and stabbed him while he leaned over to listen.--M.]
