A new online project is working toward a page-by-page transcription and interpretation of the Löffelholz Codex, a 154-page illustrated manuscript begun in 1505 by Nuremberg patrician and knight Martin Löffelholz. Its creator, engineer Dirk Schornstein, says 128 pages have been reviewed so far; 26 remain unfinished. The manuscript is held in Kraków and is freely available as a digitized copy.
Dirk Schornstein is building an online, page-by-page guide to the Löffelholz Codex, an illustrated book of tools, machines and other devices begun in 1505 by Nuremberg patrician and knight Martin Löffelholz. The 154-page manuscript is held by the Jagiellonian Library in Kraków and has been digitized, but the project says there is no complete published transcription, edition or translation; 128 pages have been reviewed and 26 are still unfinished.
The manuscript is not a diary or family chronicle, according to the project’s description. Its drawings and brief captions record subjects that include drills with interchangeable blades, tools for cutting threads, a workbench with a vise, a swivel chair on casters and a crossbow shown in separate parts. Other illustrations include a spiral staircase designed to swing out of the way and a cradle whose rockers are described as filled with mercury. The source does not establish how every depicted object functioned.
The website assigns a page to each of the codex’s 154 pages. Depending on progress, a page may include a high-resolution manuscript image, a transcription in the original spelling, a modern English reading and a proposed explanation of the object. The site also identifies surprising features and lists questions that remain open, rather than presenting every interpretation as settled.
Schornstein, a graduate engineer and technology enthusiast, says he uses AI to help with initial transcription and interpretation, but that the results are not treated uniformly. Pages labeled “raw transcription” are drafts generated with AI and have not been checked and corrected line by line. Reviewed pages are checked against the drawing, available research and the transcription. Uncertain readings are marked, undeciphered text is left blank, and explanations are identified as suggestions when their function cannot be confirmed.
Tool Book Of A Nuremberg Knight From 1505
A page-by-page effort is making the Löffelholz Codex easier to read and explore. The illustrated manuscript gathers tools, machines and other devices, with transcription and interpretation still underway.
A workshop captured in ink
Drawings and brief captions offer glimpses of early sixteenth-century making, mechanisms and everyday ingenuity.
Built for the bench
Interchangeable-blade drills, thread-cutting tools and a workbench with a vise appear among the illustrated devices.
Unexpected movement
A swivel chair on casters and a spiral staircase designed to swing out of the way hint at inventive solutions.
More than machines
The codex also includes locks, weapons, hunting equipment and recipes. A crossbow is shown in separate parts.
Progress, with room for uncertainty
Reviewed-page totals describe project progress; they do not mean every page has a complete translation or confirmed explanation.
Most pages have been reviewed; the work continues.
The project reports 128 reviewed pages and 26 still unfinished. It has not announced a completion date.
Counts are reported by the project. The source does not specify how many reviewed pages have complete English readings or firm explanations.
From manuscript image to readable guide
Each page can bring together evidence, a reading and a carefully qualified explanation.
View the page
Consult a high-resolution image of the digitized manuscript when available.
Read the script
Compare an original-spelling transcription with a modern English reading where provided.
Assess the object
Consider a proposed explanation alongside the drawing, caption and available research.
Keep questions open
Uncertain readings are marked; undeciphered text may remain blank and functions may be suggestions.
Evidence and interpretation stay distinct
AI supports early drafts, while the project labels what has and has not been checked.
| Page status | What it means | How to read it |
|---|---|---|
| Raw transcription | AI-generated draft, not checked and corrected line by line. | Preliminary |
| Reviewed page | Checked against the manuscript image, available research and transcription. | Reviewed |
| Uncertain reading | Unclear handwriting is marked; undeciphered text can be left as a gap. | Open question |
| Proposed function | An explanation may be offered when an object’s operation cannot be confirmed. | Suggestion |
A Nuremberg manuscript, held in Kraków
The digitized source is freely available, making comparison with each proposed reading possible.
Martin Löffelholz
A Nuremberg patrician—a member of the city’s ruling families—and a knight, he began assembling the codex in 1505.
Biblioteka Jagiellońska
The original is held in Kraków under shelfmark Ms. Berol. germ. quart. 132. Its digitized copy is freely available through the library’s digital collection.
Early New High German
The Nuremberg written form had no standardized spelling. Words can vary within a page, and workshop terms may be absent from modern dictionaries.
A page-by-page guide
The project says it knows of no complete published transcription, edition or translation covering all 154 pages.
Help test the readings
Public input can connect manuscript study with historical language and practical craft knowledge.
Read historical German
Help check handwritten words, spellings and proposed transcriptions.
Bring workshop experience
Woodworkers, smiths and woodturners can weigh in on tools and how they might work.
Explore difficult pages
Manuscript, technology, arms and armor, and hunting specialists are invited to contribute. Monthly mystery discussions open tricky images to public input.
Two questions worth keeping in view
The project invites close reading while leaving unresolved claims visible.
“My goal is to understand every single device in this book — and to explain it clearly to others.”Dirk Schornstein · Project creator
No finish date announced
The project gives no release date for a complete transcription or translation. It also does not establish that proposed reconstructions have been independently verified by manuscript scholars or craft specialists.
Making Workshop Drawings Accessible
The effort could make a technically varied early 16th-century manuscript easier for readers to examine without requiring them to decipher its handwritten language first. The codex is written in Early New High German, in the Nuremberg written form of the period. The project notes that spelling was not standardized, words can vary within a page, and workshop terminology may not appear in modern dictionaries.
Its value depends on keeping interpretation separate from evidence. A drawing and its caption may offer clues about an object, but they do not always establish its intended operation. By labeling uncertainty and distinguishing reviewed pages from preliminary AI-assisted drafts, the site gives readers a way to judge how firm an explanation is. The project also invites craftspeople and manuscript specialists to test proposed readings against practical and historical knowledge.

A Manuscript Begun in 1505
Martin Löffelholz was a Nuremberg patrician—a member of the city’s ruling families—and a knight. He began assembling the codex in 1505. The manuscript brings together drawings and short written descriptions of tools, machines, locks, weapons, hunting equipment and recipes, according to the project’s account.
The original is held by the Biblioteka Jagiellońska in Kraków, under the shelfmark Ms. Berol. germ. quart. 132. A digitized copy is freely available through the library’s digital collection. That public access makes close study possible, but it does not by itself provide a readable transcription or an explanation of every image. Schornstein says he has not found an existing resource that describes and interprets every page in detail; the project is intended to address that gap.
The project’s progress is uneven by design: some pages have been reviewed and corrected, while others remain preliminary. It also publishes a monthly “mystery” discussion for difficult pages and seeks contributions from people able to read the historical German, work with relevant crafts or research manuscripts, technology, weapons and hunting history.
“My goal is to understand every single device in this book — and to explain it clearly to others.”

Which Readings Still Need Checking
Twenty-six pages have not yet been reviewed, according to the project’s stated count. The source does not give a completion date or a schedule for finishing the remaining pages. It also does not specify how many of the reviewed pages have complete English readings or firm explanations, so the reviewed-page total should not be read as a claim that every entry is equally complete.
Some words and images remain difficult to interpret. The project says uncertain handwriting is marked, text that cannot be deciphered is left as a gap, and explanations of unclear devices are presented as suggestions. The source also does not establish whether any proposed reconstruction or account of how a particular machine worked has been independently verified by a manuscript scholar or a specialist craft practitioner.
Reviewing Pages With Outside Help
Schornstein plans to continue checking and explaining the manuscript page by page. The project is seeking help from readers of Early New High German, craftspeople—including woodworkers, smiths and woodturners—and specialists in historical technology, manuscripts, arms and armor, and hunting. It says contributors who help correct a page will be named on that page.
The site’s monthly mystery feature offers another route for public input on difficult illustrations. Readers can consult the digitized manuscript alongside the project’s entries, compare proposed readings with the original, and send feedback. No release date for a complete transcription or translation is provided, so the next milestone remains the completion and review of more individual pages.
