As we have said, there are very few examples in our public collections that can with any assurance be attributed to Sung times. In the British Museum, in the same case with the Kien yao tea-bowl already mentioned, is a jar some twelve inches in height, with two small handles on the shoulder. It is of irregular shape and covered with a thick glaze of a pale turquoise blue, faintly crackled. Close to the mouth is a bright red mark, like a piece of sealing-wax, due probably to the local partial reduction of the copper. This beautiful but very archaic-looking jar (PL. IV.) is attributed to no earlier date than the later or southern Sung dynasty (1127-1279). Among the large number of crackle monochrome pieces in the same collection there are many specimens which a Chinese connoisseur would classify as Ko yao, and similarly some of the old _flambé_ pieces might be termed Chün yao, without definitely assigning them to Sung times. The Lung-Chuan celadons are represented by some early pieces, more than one distinguished by the red foot. There are some fine plates of old heavy celadon at South Kensington, not a few purchased in Persia. Here may also be found a celadon jar cut down at the neck; and the ‘mouth’ thus artificially formed has been carefully stained of a red colour to imitate the old ware. The French museums are particularly rich in specimens of old _martabani_ celadon--I would point especially to several large dishes both at Sèvres and in the _Musée Guimet_. But what is perhaps the finest collection in Europe of celadon and other old wares is now to be seen in the museum at Gotha. It was brought together by the late Duke of Edinburgh, who added to previous acquisitions the collection formed in China by Dr. Hirth. YUAN DYNASTY (1280-1368).
