Steampunk literature commonly focuses on improving, constructing, and reconstructing living bodies, through living machinery, vivisections, and other techno-fantastical experimentation. These bodies are grotesque forms. Focusing on various steampunk grotesque creations and creators, and exploring the audience relationship to the grotesque through an examination of the grotesque interval, this study aims to explore how steampunk authors use these grotesques to examine their own relationship with technology and scientific progress. “Breathing Machines, Patchwork Monsters, and Mechanical Limbs: Steampunk and the Grotesque,” concludes by applying its analysis of the steampunk grotesque to the steampunk subculture, especially as this applies to costuming, art, music, and technology.
