Cantemir. I. Demetrins, hospodar of Moldavia, born Oct. 26, 1673, died Aug. 23, 1723. His father, Constantine, held the same office from 1685 to 1693, and his brother, Antiochus, from 1695 to 1701. Demetrius succeeded by appointment of the Porte in November, 1710; but in 1711 he revolted against the Porte and went to Russia, where he received from Peter the Great extensive domains in the Ukraine, with the right of sovereignty over them, and the rank of a prince of the Russian empire; and he was also made privy councillor. He aided in the establishment of the academy of St. Petersburg, and was a member of the kindred institution at Berlin. He was proficient in 11 languages, and the author of many works on Turkey, the music of the Turks, Moldavia, and the Mohammedan religion, the best known of which is the " Growth and Decay of the Ottoman Empire," written in Latin, which has not been published in the original, but has been translated into various languages (English by Tindal, 2 vols, fol., London, 1734). II. Antiochus, or Constantine Demetrius, a Russian poet and statesman, son of the preceding, born in Constantinople in 1708 or 1709, died in Italy in 1744. He was educated at St. Petersburg, officiated as Russian minister at various courts of Europe, and gained distinction by his diplomatic, but still more by his literary achievements.

Among his most noted works are his Russian translations from the classics, and his eight hooks of satires, which have been translated into French and German.
