A RARE 18th CENTURY PALE CELADON JADE CARVING OF ZHANG QIAN ON A LOG RAFTThe stone of even pale celadon hue with spare russet highlightsChina, 18th century This masterly carved jade group shows the Han Dynasty statesman Zhang Qian, seated inside a large hollowed log with a tree-form stern. He is accompanied by a young servant who is in charge of the oar and a crane is also depicted, resting inside the log. The carving is of very fine quality best visible in the russet highlighted leafage of the tree or the knot-holes covering the entire vessel. Zhang Qian was a Han dynasty imperial envoy and traveler. The subject of Zhang Qian in his log boat was a popular theme during the Ming and early Qing periods, and is most often seen in rhinoceros horn carvings, such as the three examples illustrated in The Complete Collection of Treasures of the Palace Museum - 44 - Bamboo, Wood, and Rhinoceros Horn Carvings, Hong Kong 1999, nos. 118-20. Rhinoceros horn examples are in numerous public and private collections, several of which are illustrated by T. Fok, Connoisseurship of Rhinoceros Horn Carving in China, Hong Kong, 1999, nos. 70-4. The representations of Zhang Qian, as well as the log raft, vary in these carvings.These carvings, as well as the present jade vessel, may all have been inspired by the famous silver example formerly in the collection of the late Lady Percival David included in the exhibition, Chinese Art under the Mongols: The Yuan Dynasty (1279-1368), Cleveland Museum of Art, 1968, no. 37.
