Steampunk is a counterfactual: what if the Victorian era had developed computing, aviation, and powered machinery without electricity? The visual answer is the aesthetic — brass gears, copper piping, riveted iron, leather and goggles, the persistent question of what 19th-century engineering would look like taken to its logical extreme.

The term "steampunk" was coined by science fiction writer K.W. Jeter in 1987 as a joking variation on "cyberpunk" — explicitly acknowledging the parallel: both imagine technology dominating human life, one through corporate digital power, one through industrial mechanical power. Jeter was describing a fiction genre; the aesthetic that followed was built by a community of makers, costumers, and designers over the following two decades.

The Victorian source material is precise. The Great Exhibition of 1851 at Crystal Palace, London, established the template: the celebration of industrial machinery as spectacle, the display of mechanical ingenuity as cultural achievement. The aesthetic of industrial Victorian engineering — functional and ornamental simultaneously — is the steampunk inheritance. The gear is always visible. The mechanism is always on display.
