An Iron Forge

Joseph Wright of Derby painted An Iron Forge around 1772, one of his most celebrated industrial subjects depicting the interior of a forge where iron is being worked by hammer and bellows into the specific industrial setting of Midlands manufacturing. The forgemaster and his workers are illuminated by the incandescent heat of the heated iron, a light source that replaces the candles of his earlier scientific subjects with the more violent, industrial luminosity of metalwork. The subject was unprecedented in serious painting — the interior of a working forge treated with the dramatic tenebrism and philosophical weight normally reserved for scientific experiment — and represents Wright's most sustained engagement with the industrial transformation of his region.

The composition is organized around the central blaze of the forge, which illuminates the muscular workers in dramatic chiaroscuro. Wright's virtuosic rendering of firelight reflecting off metal, flesh, and surrounding darkness creates a powerful nocturnal effect.
