Begun in 1505 by Martin Löffelholz von Kolberg, a Nuremberg patrician and knight, the Löffelholz Codex is a 154-page illustrated “tool book,” not a diary or family record. Its drawings and brief captions cover tools, machines, locks, weapons, hunting equipment, and recipes. Among its striking designs are a drill with interchangeable bits, a swivel chair on casters, a wheel-lock fire striker, a crossbow shown in parts, and a cradle with mercury-filled rockers. The manuscript also depicts shackles and locks, perhaps reflecting Löffelholz’s experience of captivity, and is now held in Kraków, where a digitized copy is freely available.
A project launched by engineer Dirk Schornstein aims to make every page understandable through high-resolution images, original-language transcriptions, modern English readings, and explanations of how the objects may work. At the time described, 128 pages had been reviewed and 26 remained unfinished; no complete published transcription or translation was known. The project distinguishes checked pages from AI-generated draft work, marks uncertain readings, leaves illegible passages blank, and labels explanations as suggestions when functions are unclear. Its goal is to combine manuscript research with practical knowledge from craftspeople and technology historians, while inviting readers to help transcribe, interpret, or build replicas. The result offers a guided look at early-sixteenth-century technology while being candid about what remains uncertain.
