A detailed engraving displays a lathe in operation. A man in period attire stands at the right, using a handheld tool to carve a vessel spinning on the lathe. Above the apparatus, a shelf displays four finished vessels. The four cardinal directions are labeled: Northern Line at the top, Southern Line at the bottom, Western Line on the left, and Eastern Line on the right.
