Armillary Sphere

The armillary sphere is the oldest model of the heavens still made by hand: a cage of graduated brass rings — equator, ecliptic, colures, tropics — wrapped around a small central globe. Refined from Greek antiquity through Renaissance instrument workshops, it survives in museum cases as patinated gold against a deliberately dark display ground. This system borrows that exact staging: warm brass rings and engraved Roman capitals lit against a deep near-black void, where every line of degree-marking and zodiac glyph earns its glow.

浑天仪是至今仍以手工制作、最古老的天体模型：赤道、黄道、二分二至圈、回归线等一圈圈刻度铜环， 环抱着中央的小地球。它自希腊古典时期一路经文艺复兴的仪器作坊不断精炼，如今多陈列于博物馆展柜， 暗色背景衬出锈金光泽。本设计系统沿用这种陈列手法：温润的黄铜环与镌刻的罗马大写字母，在深近黑的 虚空中发亮，让每一道刻度线、每一枚黄道符号都各得其光。
