In 1505, Nuremberg patrician and knight Martin Löffelholz began compiling a unique tool book. The manuscript contains drawings of drills with interchangeable blades, thread-cutting tools, a vised workbench, a swivel chair on casters, and a crossbow disassembled into parts. One page features a cradle with mercury-filled rockers. The codex, now digitized and in the public domain, resides in Kraków. After 500 years of being unread in full, a new project aims to transcribe and interpret every page.
The project presents each of the 154 pages individually, offering the facsimile in high resolution, the original spelling transcription, a modern English reading, and a suggested interpretation. Six pages are currently available to start. The initiative emphasizes editorial review, with pages carefully checked for accuracy. Uncertain passages are marked in color, and interpretations are labeled as suggestions.
Project lead Dirk Schornstein, a graduate engineer, uses AI for groundwork but oversees every reviewed page. The project seeks public contribution, specifically readers of Early New High German or craftspeople like woodworkers and smiths, to help interpret the devices. A monthly mystery series tackles difficult pages, with the current October 2026 mystery focusing on a dagger page.
