Ku K'ai-Chih (circa 345-c. 405), Chinese painter of the Six Dynasties period, one of the greatest artists of Chinese antiquity. In his art, he reacted against the brightly colored, artificial style of his day to concentrate on drawing human figures with considerable sensitivity and gracefulness. Few of his paintings remain in their original form—his famous portraits and religious pictures have all disappeared—but one silk scroll, Admonitions of the Instructress to the Court Ladies (British Museum, London), is either an original or a very early copy. It illustrates his style of delicate, almost wispy figures that seem to float on the surface of the scroll. Nymph of the Lo River, an attributed work existing in two copies (Freer Gallery, Washington, D.C., and Palace Museum, Taiwan), is credited by traditional Chinese art historians as being one of the first and most influential Chinese landscape paintings.
