This tower was made for burial in a tomb. Stilts support a single platform with a tile roof above a moat or pool in the form of a bronze basin. There are nine figures in the tower, among them a long-sleeved dancer performing at the center of the platform surrounded by four clapping figures. An archer with a drawn crossbow stands at each corner. The presence of the six birds on the roof indicates the gathering of spirits, and abundant fish in a moat are an equally auspicious sign. The place of people in the natural world has been deeply important in China. Rituals directed toward mountains, rivers, woods, birds, and animals as well as careful observation of these natural elements guided action or position in the world. Towers, which were associated with mountains, were among Han dynasty (206 BCE–220 CE) structures used to communicate with immortals who inhabited mountainous regions.
