The brass orrery is the clockwork cosmos of the European Enlightenment — geared planets riding their orbits above a dark stained-wood base, built by London makers like John Rowley and George Graham around 1750. Its identity is bright polished brass mechanism glowing against near-black aged mahogany: precision gearwork, engraved horizon plates, and the warm patina of worked metal. This is a scientific instrument's gravitas — gold-on-dark-wood, never parchment cream.
黄铜天体仪是欧洲启蒙时代的发条宇宙——齿轮驱动的行星沿轨道运行，悬于深色硬木 底座之上，由约翰·罗利、乔治·格雷厄姆等伦敦仪器匠师在约 1750 年打造。它的视觉 灵魂，是明亮的抛光黄铜机构在近乎黑色的陈年红木上熠熠生辉：精密的齿轮、镌刻的 地平圈刻度盘、以及金属经年打磨后温润的包浆。这是科学仪器特有的庄重——金色铭刻 于深木之上，绝非羊皮纸的米白。它讲的是理性与精度的故事，工整、克制、贵气。
