description: "Zhang Sixun was a Chinese astronomer and mechanical engineer from Bazhong, Sichuan during the early Song dynasty. He is credited with creating an armillary sphere for his astronomical clock tower that employed the use of liquid mercury. The liquid mercury filled scoops of the waterwheel would rotate and thus provide the effect of an escapement mechanism in clockworks and allow the astronomical armillary sphere to rotate as needed."
