Shang (1751-1111 BC) and Chou (1111-221 BC) dynasty bronzes can be divided into four basic types: food vessels, wine vessels, musical instruments and weapons. The yu pictured here is a type of wine vessel popular from the late Shang to early Chou. Because the character ke(spear) has been carved into both the lid and base, the piece is known as a ke yu. The shape, design, and color of this bronze make it one of the most exquisite pieces in the National Palace Museum collection.
The ke yu is 33.1 cm in height (including handle) and 18.9 cm deep. It is covered with designs, the most important being the tao-tieh mask on the lid and front, the cicada on the handle, and the kuei monster design on the ears, handle, rim, and base.
The tao-tieh mask is one of the most common features found on Shang bronzes and its protruding horns, eyes, nose, mouth, and feet are all easy to distinguish. Some say that the tao-tieh is a representation of gluttony while others say it is the most abstract design to be found in ancient Chinese art.
The cicada is a symbol of good fortune and therefore is often seen in bronze designs. The kuei is a dragon-like design. On the side of the yu can be seen a horn, a foot, an open mouth, and a tail all in geometric style.
