circa 1815

　This exquisite compound instrument was crafted by William Jones, a renowned British manufacturer of precision scientific instruments active in the 18th-19th centuries. Through its ingenious system of geared mechanisms, rotating arms, and oil-lamp accessories, the device dynamically demonstrates heliocentric principles, diurnal cycles, seasonal variations, and eclipse phenomena through projected light effects. Blending didactic functionality with exceptional craftsmanship, it stands as a paradigmatic example of late Georgian scientific instrumentation – where mechanical precision met astronomical pedagogy.
