Roger De Hoveden, an English chronicler, born in Yorkshire about the middle of the 12th century. He was attached to the court of Henry II., and was employed in visiting monasteries, and in watching over the revenues that accrued to the king on the death of the superiors. His history, Annates Rerum Angli-carum, is a continuation of the ecclesiastical history of Bede, beginning where he left off (731), and extending to 1202, the third year of the reign of King John. Its accuracy is attested by Sir Henry Savile, Selden, Leland, and Nicolson. It was published in Savile's Scriptores post Bedam (London, 1595), and translated by H. T. Riley for Bohn's " Antiquarian Library."
Roger Long, an English clergyman and astronomer, born in Norfolk about 1680, died in Cambridge, Dec. 16, 1770. He graduated at Cambridge in 1704, became vice chancellor of the university in 1729, and master of Pembroke hall in 1733. In 1749 he was appointed Lowndes professor of astronomy, and in 1751 rector of Bradwell in Essex. At his death ho bequeathed £600 to his college. He was the inventor of the uranium, a singular machine for facilitating the study of astronomy which may still be seen at Pembroke hall. It is a hollow sphere 18 ft. in diameter, and capable of containing 30 persons. The inner surface is covered by a map of that portion of the heavens visible in Britain. The most important of his works is his "Treatise on As-tronomy," in 5 books (2 vols. 4to, Cambridge, 1742-'64; 2ded., 1784).
Roger Van Bruges, a Flemish painter, pupil of John van Eyck, flourished about the middle of the 15th century. He was probably the same person as Magister Rogel of Flanders, who painted a " chapel" or altarpiece in three compartments, which was presented by John II. of Castile to the Carthusian church at Miraflores in 1445, and which Charles V. used to carry with him in all his expeditions. He was one of the few artists of his time who painted on canvas.

Roman Emperor From April Macrinus, A. D. 217, to June, 218, born in Caesarea, Mauritania, in 164. Of the humblest parentage, he was admitted into the employment of Plautiamis, the favorite of Septimius Severus, and received successive appointments in the imperial household, until he became prefect of the praetorians under Caracalla. On the death of the latter, whose assassination he plotted, he was proclaimed emperor, gaining the favor of the praetorians by a liberal donative and of the senate by repealing some obnoxious taxes. He immediately marched against the Parthians under Artabanus, and was signally defeated by them near Nisibis. His enforcement of discipline caused disaffection among his troops, a portion of whom renounced their allegiance to him in favor of the pretender Elagabalus. He marched against the latter, was defeated at Antioch, fled in disguise to Chalcedon, was betrayed, and was put to death in Cappadocia.
