I
Weathering as witness
Each layer of verdigris records decades of rainfall chemistry—a climatological archive written in copper carbonate.
II
Inscription over impression
Engraved Roman capitals survive centuries of acid rain; painted signage fades within a single generation.
III
Mass that resists erasure
A two-ton bronze casting endures where steel rusts through and stone spalls—density is durability.
IV
A record carved in metal
We laser-scan every inscription at sub-millimeter resolution before time and pollution can steal another letter.
