Craftsmen Constructing Mechanical Astrolabe

A towering brass astrolabe dominates a timber-framed workshop, its engraved rings and zodiac markings catching light from arched stained-glass windows on both levels. Below the great instrument, two artisans lean over a spread of hand-drawn diagrams, comparing measurements with calipers close at hand. To the right, workers climb ladders to fit large turquoise discs into the mechanism, while others polish smaller gears against the wall. A second, smaller clock face sits nearby on a side table, and a man carefully engraves the rim of a golden ring at a cluttered workbench. Above, an upper gallery holds onlookers in patterned robes, watching the work below through a wooden railing. Every gear, ring, and diagram sits as its own task, so the whole workshop splits naturally into stations around the great wheel.
