185 Small Container for Pigments
Fine-grained greenish black stone with a largely discolored, slightly eroded surface, of a hardness inferior to jade. The body has the form of a cube whose sides narrow toward the bottom. Its recessed base rests on four quadrangular feet. Into the body are drilled four tubular holes, the rims of which rise above the surface that has been ground level around them. From the narrowest side of the cubic body springs a handle-like member that terminates in the head of a water buffalo with incised and sparingly modeled features. The only decoration on the body consist of horizontal ridges (two at the top, one at the bottom), on the three sides facing away from the buffalo protome. Shang or early Chou.
