The Principles of Perpetual Motion

Precision measured in thousandths
Each gear tooth hand-filed to tolerances of three-thousandths of an inch, ensuring celestial bodies track their ordained paths without deviation.
Light captured in polished brass
Reflective surfaces calibrated to illuminate orbital paths in candlelit chambers, turning the mechanism into its own source of revelation.
Orbits traced by mathematics alone
Kepler's laws rendered in clockwork, where every planetary period is computed by gear ratio rather than approximation or conjecture.
Patina as proof of permanence
Two hundred and fifty years of oxidation, and the mechanism still turns — each mark of age a testament to enduring craftsmanship.
