MOHAMMED EFFENDI, a celebrated Turkish historian, was born in the early part of the sixteenth century, and was educated among the pages of the imperial palace. The influence of his father and his own acquirements raised him to a high position in the world. Several emperors in succession patronized him. Selim II. made him preceptor to his son the heir-apparent. Mourad III. appointed him military judge, and instituted for him the new office of imperial historiographer. Still more marked were the favours of Mohammed III. He kept him in his presence as his confidential councillor, raised him to the dignity of mufti, and continued to cherish him till death carried him off in 1599. The great work of Saad-Ed-Deen treats of the history of the Ottoman empire from its foundation by Ottoman to the death of Selim I. in 1520. Speaking of it, Sir William Jones says that, "for the beauty of its composition and the richness of its matter, it may be compared with the finest historical pieces in the languages of Europe." It is still in manuscript.
