diagram

A large woodcut diagram illustrating a surveying or astronomical instrument, likely a gnomon or sundial setup. The central feature is a square frame containing concentric circles. A tall, tapered vertical gnomon stands at the center, casting a shadow. Above it, a horizontal sighting arm or rod extends from the left, labeled with the character "乙" (Yi) at its tip. The square frame has four decorative corner pieces resembling small vessels or weights. Within the circles, a triangular frame (resembling a square or level) is positioned at the bottom, labeled with "戊" (Wu) and "己" (Ji). Other directional or coordinate labels include "丙" (Bing) on the left and "甲" (Jia) on the right. In the background, a landscape is depicted with rolling hills or mountains and water or flat ground indicated by horizontal lines. To the right of the main diagram, a vertical label reads "五十六圖" (Figure 56). 五十六圖五十六圖, 乙, 丙, 甲, 戊, 己
