Binding It All Together – A Review of the 2025 Summer School in Digital Palaeography

Written by Phillip Landgrebe, PhD candidate at the University of Kassel.

From 10 to 22 August, the Summer School in Digital Palaeography took place at the University of Göttingen, bringing together postgraduate students from across the globe. The programme combined introductions to Latin book scripts, codicology, and manuscript description with the teaching of digital methods, tools, and approaches relevant to the study of medieval manuscripts. Some sessions were held in the Historical Building of the SUB Göttingen, where participants could work directly with manuscripts and gain insights into the application of multispectral imaging and digital microscopy.

The Summer School thus fills an important gap. Traditional courses in palaeography or codicology typically devote little attention to digital components, while digital humanities workshops often do not adequately cover the essential knowledge of the auxiliary sciences of history. The concept developed by Dr. Anna Dorofeeva and her team addresses this challenge effectively, as evidenced by the large number of applications for the sixteen available places.

The sessions were characterised by the instructors’ high level of engagement, who encouraged participants to experiment and interact thoroughly with the material. Complex topics, such as working with TEI-XML or understanding an IIIF manifest, were presented in a clearly structured way with numerous practical recommendations. The programme repeatedly offered revealing insights, for example, into how the measurement of pixel scales in manuscript images can aid in the identification of forgeries. Additionally, the hands-on creation of different types of bookbindings proved both instructive and enjoyable.

The summer course was particularly productive when theoretical input was combined with independent work on the materials. For instance, after an introduction to fragmentology, participants catalogued Göttingen fragment holdings using Fragmentarium. A later excursion to the Herzog August Library in Wolfenbüttel built upon this work, enabling participants to analyse previously unstudied fragments in manuscript bindings and document them in Fragmentarium again.

I would like to express my gratitude to the entire Göttingen team for the excellent organisation and the conducive working environment during the Summer School, which, both within and beyond the sessions, was marked by great helpfulness and warmth, providing all participants with an extraordinarily enriching experience.

Short Report on the Summer School in Digital Palaeography

Written by Käthe Sophie Hanschmann, PhD candidate at Friedrich-Schiller-Universität Jena

There are many good things to say about this summer school, especially regarding its thematic variety. We began with a general introduction to scripts, focusing on how to read and recognize them, along with an introduction to codicology. More importantly, the traditional lectures were complemented by practical exercises.

In the library session, we had the chance to sew quires, work with manuscripts, and analyze fragments, applying the knowledge we had gained earlier. We also enjoyed guided tours of the Göttingen State and University Library (SUB), its conservation department, and the Bibliotheca Augusta in Wolfenbüttel.

Personally, the highlight of the program was the overview of digital tools in palaeography. Many existing tools were completely new to us before joining the program. After several practical sessions where we could test the tools under expert guidance, it was inspiring to discover so many programs, methods, and ongoing projects.

The program as a whole was both enjoyable and intense. Fortunately, the welcoming atmosphere made it easy not to feel overwhelmed by the long days. Our lecturers skillfully managed the challenge of addressing participants’ different levels of knowledge and created a motivating learning environment. They carefully selected the manuscripts in the university archive that connected to our own research interests, allowing us not only to gain an overview of the wide field of digital palaeography but also to reflect on our individual projects.

I can therefore only say thank you and recommend this summer school to everyone.

Seshat: A Digital Measurement Tool for Analysing Medieval Manuscripts

What is Seshat?

According to an apocryphal story, Lord Kelvin or as now believed, Albert A. Michelson, declared in 1900:

“There is nothing new to be discovered in physics now. All that remains is more and more precise measurement.”

Is the fate of palaeography similar? In 1979 the distinguished palaeographer Bernhard Bischoff inadvertently touched on this question when he wrote in the introduction of his handbook that palaeography was being transformed in his time “from an art of seeing and sympathetic understanding” to “an art of measurement” (Paläographie des römischen Altertums und des abendländischen Mittelalters [Berlin, 1979], p. 17). The statement triggered heated reactions and defences of palaeography as an art of cultivated seeing. Our new digital tool Seshat is not intended to promote the idea that palaeography should be a purely quantitative discipline. But it does enable users to measure key features of scripts from high-quality images, which is both useful and desirable in the digital age.

Named after the Ancient Egyptian goddess of scribes, Seshat is a measurement tool with annotation features that make it possible to conduct a thorough palaeographical analysis of a digital object. It allows users to highlight textual regions, underline specific words or lines, insert comments, trace letterforms using adjustable pen angles (0°, 25°, 30°, 50°, and 80°), and excerpt data in different formats to be used as a dataset later. The tracing functionality supports the analysis of script ductus and scribal hand variation.

Taking inspiration from the first version of a software tool for the critical examination of historical handwriting called Graphoskop developed by Maria Gurrado and Giancarlo Lestingi (https://www.irht.cnrs.fr/fr/ressources/sites-web-outils-corpus/graphoskop), we have included a suite of measurement tools that calculate horizontal and vertical distances for particular script and page features: ascender and descender heights, interlinear spacing, margins, overall line heights, and inter-column spaces. A stroke angle measurement feature allows for precise documentation of letterform direction and inclination. Statistical tools automatically calculate averages, standard deviations, and mode values across measurements for both single pages and entire manuscripts.

Seshat is fully IIIF-compatible, enabling users to load manuscript images from major repositories such as the British Library, the Vatican Library, or other IIIF-compliant archives. The option to upload JPEG formatted images is also available. Image cropping functionality is built in, letting users isolate manuscript regions and export these selections in PNG or SVG formats, with or without annotations.

What were our goals when starting to develop this app?

When we started, our main goals were:·To provide a digital tool for precise annotation and measurement of palaeographic features (e.g. ductus, margins, letterforms).

To simulate traditional palaeographic tracing methods (such as ductus analysis) in a digital environment by including adjustable pen angle tracing.

To allow users to collect measurable data (distances, angles) and automatically generate statistical outputs to support comparative manuscript studies.

To enable scholars to manipulate and export parts of manuscript images for publication or focused analysis.

To ensure integration with IIIF resources for direct access to high-quality manuscript images without requiring local uploads.

Currently, Seshat includes all the functionalities listed above, and is already being applied successfully in internal research for ductus evaluation, scribal variation analysis, and manuscript layout studies.

Seshat in the Future

Seshat is not yet finished. Based on development and user feedback, we plan the following additional features:

Tracing

Allow users to form strokes with a simulated quill, where the quill size is determined by selecting two points on the canvas in pixels. This size will be adjustable.

Support saving both individual and clustered strokes together with the underlying cropped manuscript image.

Commenting

Allow customization of comment text, including font family, font size, and colour, displayed on a transparent layer (removing the current speech bubble design).

Enable adjustment of text appearance (font, size, colour) for clearer comment placement without obscuring manuscript details.

Measurement

Integrate tracing and measurement tools to allow for linked analysis (e.g. measuring traced strokes).

Provide pixel-based measurements that can be converted to standard units.

Enable curve measurement and potentially measure nib (quill) width directly from the stroke trace data.

Alphabet selection

Develop an alphabet selection tool to extract individual letter shapes defined by the user.

Moving forwards, we will be improving Seshat based on user feedback and will be doing our best to deliver a very user-friendly interface by spring 2026!

Proteus: A Tool to Simplify Post Processing of Multispectral Images

In manuscript studies, scholars often encounter texts that are barely legible from centuries of damage, reuse as in the case of palimpsests, faded ink, or chemical reactions. Multispectral Imaging (MSI) has emerged as a way to recover such hidden texts, capturing images of manuscripts under different wavelengths of light to reveal what the naked eye can no longer perceive.

While MSI is a successful and useful technique for text recovery, the tools required to process MSI images are often intimidating. Many existing applications assume a high degree of technical knowledge, from a chemical literacy to skills in navigating dense software menus. This steep learning curve can be a barrier for students and researchers who are new to the field.

A Tool for Everyone

Our goal was to develop a lightweight app with a simple, intuitive interface that enables users—especially those without a technical background—to explore MSI data without coding.  We envisioned Proteus not just as a tool, but also as a guide: something that helps users navigate MSI post-processing with ease, without becoming imaging experts, by giving simple instructions on what images or features should be used for certain scans.

Instead of offering dozens of rarely-used features, Proteus focuses on a few impactful tools, delivered through a simple interface. We designed the interface so that each function is explained via pop-up tips, recommends effective image combinations for different tasks, performs the heavy computations silently in the background, and is supported by our MSI tutorials for a better understanding of the whole process. Our aim was to allow scholars to focus on interpreting texts, not on configuring software.

Simple and Sustainable Design

Proteus is built in Python, using libraries like OpenCV, NumPy, Pillow, and tkinter. This combination allows us to offer real-time image processing inside a platform-compatible graphical user interface. The GUI, powered by tkinter, makes image enhancement accessible through point-and-click interactions— which comes in handy for users with humanities backgrounds.

Users can load certain image stacks taken using multispectral imaging systems into the app, choose which feature to use, and select bands for further processing.

Among Proteus’s core features are:

 – Pseudo-color images, which enhance contrast by combining spectral bands as RGB channels.

– Principal Component Analysis (PCA), which mathematically isolates features that reveal faded or overwritten text.

– Power, which intensifies each pixel in the image to get a better result, especially on faded pages.

These enhancements are powered by matrix operations (via NumPy) and OpenCV functions for tasks like histogram equalization, resizing, and denoising. Proteus also follows standardized naming conventions for exported images, and delivers a text file with the metadata, including a record of used features. This makes it easy to manage results across projects.

The app’s modular code design ensures future extensibility—whether for supporting more spectral formats, integrating machine learning, or adding new filtering methods.

The Current Version of Proteus

The first working versions of Proteus have already been actively used the app in internal projects and tasks. Following evaluations with Dr. Anna Dorofeeva and Dr. Alexander Zawacki, and with the assistance of our MSI team, we’ve gathered valuable feedback—pinpointing both bugs and areas for improvement.

This feedback is now shaping Proteus v3.0, which will feature improved performance, bug fixes, and new features inspired by user experience. We’re also excited about early experiments using Proteus on non-MSI images, where enhancements like PCA and contrast filtering have revealed details even in ordinary scans.

What Next?

Proteus is built in accordance with the principle that digital manuscript tools should be clear, simple, and powerful. We want to minimise the time spent on post processing and allow researchers to make the best use of their time.

We intend for Proteus to become a standard teaching and research tool in digital humanities programs, especially in MSI training units. By simplifying complex workflows, it will lower the barrier for students and scholars – even those with limited technical skills – to engage with multispectral imaging.

As the field of manuscript studies embraces new technologies, we believe tools like Proteus can lead the way—quietly doing the heavy work, while putting discovery back in the hands of the user.

One Year of eManuSkript: A Digital Journey into Manuscript Studies

One Year Anniversary of Project eManuSkript: Part One

In April 2024, a group of scholars and students, funded by the Stiftung Innovation in der Hochschullehre, came together at the University of Göttingen’s Institute for Digital Humanities with an ambitious goal: to reimagine how medieval manuscripts can be taught, studied, and experienced in the digital age. Led by Dr. Anna Dorofeeva, Project eManuSkript has grown since then into a vibrant, interdisciplinary project that continues to evolve—shaped by its users, enriched by its team, and rooted in a shared commitment to accessibility and collaboration.

The Vision Behind eManuSkript

The idea was simple but important: manuscript studies, often remain difficult to access, especially for beginners or those outside of specialized institutions. Scholars might face barriers due to geographic distance, limited physical access to manuscripts, or a lack of training in palaeography or codicology.

Our goal was to build tools that would meet learners and researchers where they are—whether in the classroom, at an archive, or online. We wanted to create a digital platform that was not only technically sound but also inviting, accessible, flexible, and pedagogically grounded. The user experience and the needs of students in manuscript studies have driven the development of the project.

• • •

What We’ve Built

Over the past year, the eManuSkript team has been developing a suite of interconnected tools designed to address a range of issues associated with teaching and learning medieval manuscripts. Each one tackles a different challenge, and together they form a single interface.

Mergen is our AI-based layout segmentation app. It detects key manuscript elements—both text and paratext—with exceptional speed and accuracy, outperforming other existing segmentation tools and datasets. By using Mergen, the user can build a research corpus of specific manuscript elements. Using a three-layer segmentation method, our team annotated a significant corpus of raw manuscript pages to make sure Mergen reaches its potential in the shortest time. We still continue to update Mergen’s database regularly for even better results. ㅤㅤㅤㅤㅤㅤㅤ

Ceres &Libera are two connected applications for exploring medieval bookbinding. Ceres, allows users to generate customised templates to visualise medieval manuscript bookbindings. For this app, our team’s plan to document the spine and sewing structures of a medieval book have been supported by expert input from conservators at the Göttingen State and University Library. The second app, Libera, is an interactive application where users can build their own codex from bookblock to cover. With Libera, users will be able to follow simplified tutorials as they build their codex and can build visualizations with specialized terminology and professionally illustrated components.

Supporting these tools is a rich range of interactive tutorials—including images, videos and interactive games—as well as a historical timeline and canonical script alphabets with ductus practice options. Accessibility is built into every layer: visual alternatives for those with impairments, multimodal learning options, and a user-friendly design that reduces the barriers to working with manuscripts.

These applications reflect our experimental approach to manuscript studies. Despite the growing number of digitised collections, access is still limited by the high level of specialist knowledge required. Through regular team meetings, in-class experimentation, and constant dialogue between developers, scholars, and students, we’ve shaped tools that genuinely respond to user needs—pushing boundaries while remaining grounded in traditional scholarship.

Together, these five tools create a full digital environment for investigating the medieval manuscript book—from physical structure and visual layout to textual content and palaeographic detail. By April 2026, all applications will be available through our website, and our datasets and backend code will be archived openly via GitHub and Zenodo. This suite of tools and tutorials will be complemented by an extensive glossary and Zotero library. We hope this will empower others to build upon our work and bring manuscript studies fully into the digital age.

People and Collaboration at the Heart

What truly powers Project eManuSkript is its team. Beginning as a group of ten, with backgrounds in history, digital humanities, computer science, German studies, English literature, and more, our team has changed over time, but what has remained consistent has been the interest the project has generated — from students to guest researchers, all enriching our ideas with fruitful support and feedback. Our collaboration is intentionally non-hierarchical and inclusive. We believe that the best solutions emerge from diverse perspectives and shared responsibility.

Team members contribute in many ways: designing user interfaces, labelling datasets, testing OCR models, writing documentation, or organizing outreach events. Each of us brings a unique angle, and we encourage constant feedback—especially from our fellow students at the Institute of Digital Humanities, who are both co-creators and core users of the tools.

• • •

Challenges and Lessons Learned

Of course, no digital project is without hurdles. Training machine learning models on historical scripts has meant confronting the limits of existing datasets and annotation tools. Designing interfaces for a multilingual, cross-disciplinary audience has forced us to think carefully about clarity and adaptability. And balancing research with usability remains an ongoing effort.

But these challenges have been productive. They’ve taught us to take a step back and recalculate, document thoroughly, and centre accessibility at every stage. We’ve also learned the value of working in public: sharing early prototypes, inviting critique, and adapting based on what users actually need.

• • •

What’s Next?

As we move into our second year, we’re expanding in different directions. This year, we’re refining our tools with the help of classroom testing, user studies, and more targeted community engagement. We are hoping that, by releasing our website for Project eManuSkript, we will encourage a larger public to explore our current work, both to offer constructive criticism and feedback on what we have accomplished so far and to measure their accessibility and practical usability for scholars and students from all around the world.

We are continuously working to make the best out of each app and expand the limits of our tutorials by going beyond the traditional approach. Going forward, we will continue to generate new ideas, to maintain outputs that are open, free, and adaptable, and, ultimately, to develop the best technologies we can for digital manuscript studies.
