Thornhill, Sir James

▪ English painter

born July 25, 1675, Melcombe Regis, Dorset, Eng.

died May 13, 1734, Thornhill, Dorset

      English painter, the first to excel in historical painting, whose style was in the Italian Baroque tradition.

      Thornhill became the history painter and sergeant painter to George I and George II, master of the Painters' Company in 1720, fellow of the Royal Society in 1723, and member of Parliament from 1722 to 1734 and was knighted in 1720. He was one of the original directors of Kneller's Academy of Painting, and when this closed, and he had failed to establish a “royal academy,” he opened his own drawing school, which also proved unsuccessful.

      The eight scenes in the dome of St. Paul's Cathedral (1715–19) and the allegories in the Painted Hall, Greenwich Hospital (1708–27), are his two most considerable works. His paintings were largely executed on the ceilings and stairs of such country houses and palaces as Hampton Court, Blenheim, and Chatsworth. Among Thornhill's few canvases are the altarpiece for St. Mary's Parish Church, Weymouth, and a group portrait of the members of the House of Commons in which he was assisted by William Hogarth (Hogarth, William), his son-in-law. Thornhill also did portraits (his sitters including Isaac Newton and Richard Steele), book illustrations, theatre scenery, and the rose window of the north transept of Westminster Abbey (1721).
