diagram

A technical illustration from a Chinese scientific or engineering treatise. At the top, a compass (divider) is shown measuring a circular diagram on a landscape background. The circle is marked with the characters 甲 (Jia), 乙 (Yi), and 丙 (Bing). Above this is the vertical title "五十五圖" (Figure 55). On the left, a large mechanical screw-driven drafting or surveying instrument is partially visible, with its points resting on a base marked 庚 (Geng) and 辛 (Xin). In the center and right, there are four distinct mechanical components or templates shown in perspective: 1. A heart-shaped plate with three holes, marked 壬 (Ren). 2. A cylindrical sleeve or socket with a flanged base, marked 壬 (Ren). 3. A teardrop-shaped plate with three holes, marked 壬 (Ren). 4. A pentagonal plate with three holes, marked 壬 (Ren). The background features light horizontal lines suggesting a ground plane or water. 五十五圖五十五圖, 甲, 乙, 丙, 庚, 辛, 壬
