Hidden Inscriptions Unearthed on 16th-Century German Sword Through Advanced CT Scanning
A seemingly unremarkable, heavily corroded sword has yielded a remarkable secret thanks to cutting-edge computed tomography (CT) technology. Researchers at the University of Jena in Germany have virtually peeled back centuries of rust to reveal intricate details, including the name of the sword’s maker and clues about its original owner.
The discovery offers a rare glimpse into the lives of Renaissance-era nobility and the skilled artisans who served them, demonstrating how modern science can unlock the stories embedded within historical artifacts.
A Relic Resurrected: The Story of the Jena Sword
The shortsword, a type known as a degen, dates back to 1558, a period coinciding with the founding of the University of Jena and the flourishing of the German Renaissance. Ownership of such weapons was restricted to the upper classes, and the university itself became a central hub for the region’s elite.
Between 1594 and 1814, the grounds of the Collegium Jenense, the university’s central church, served as a burial site for professors, students, and their families. These graves were often accompanied by symbolic offerings and personal possessions, including swords.
Tragically, the Collegium Jenense was largely destroyed during Allied bombing raids in the closing stages of World War II, burying centuries of history under tons of rubble. Years of painstaking excavation eventually brought these relics to light, though many remained obscured by corrosion.
The sword in question, along with other recovered artifacts, was carefully archived. However, it wasn’t until 2018 that researchers initiated a project specifically focused on the Collegiate Quarter’s graves. Recognizing the potential for deeper investigation, they sought the technology to peer beneath the layers of rust. A collaboration with INNOVENT, a research facility at the university, proved pivotal. INNOVENT’s newly acquired X-ray, micro-, and nano-CT scanner provided the necessary tools to unlock the sword’s secrets.
The CT scans allowed researchers to generate images of the sword’s various material layers, using false colors to differentiate between them. Green highlighted the remnants of the sword’s sheath, fused to the blade’s steel, while red revealed an elaborate inlay on the opposite side – and, crucially, the name “Clemes Stam.”
Further investigation revealed that Clemes Stam was not the sword’s owner, but rather a renowned blacksmith from Solingen, Germany, active in the late 16th century. Solingen was, and remains, a center for high-quality swordmaking, producing weapons for European nobility and even royalty. The inclusion of the maker’s name on the blade was a mark of prestige, signifying both the owner’s status and the sword’s exceptional craftsmanship.
Researchers believe the sword likely belonged to either a university rector or a student from a noble family. What does this discovery tell us about the social dynamics and material culture of Renaissance-era Germany?
“CT doesn’t just capture surface details; it reveals the object’s inner story,” explained project archaeologist Enrico Paust. “In this case, it literally uncovered a name that connects Jena to the European tradition of sword-making.”
The use of CT scanning in this instance highlights the power of interdisciplinary collaboration and the potential for technological innovation to rewrite our understanding of the past. Could similar techniques unlock further secrets hidden within other historical artifacts?

Frequently Asked Questions About the Jena Sword Discovery
What is computed tomography (CT) scanning and how does it work?
CT scanning uses X-rays to create detailed cross-sectional images of an object. These images can then be combined to create a 3D model, allowing researchers to examine internal structures without physically dissecting the artifact.
Why was the name of the blacksmith, Clemes Stam, significant?
Engraving a blacksmith’s name on a sword was a sign of prestige, indicating the weapon was crafted by a renowned artisan and intended for a high-status owner. It served as a mark of quality and origin.
What does the discovery of this sword tell us about Solingen’s role in Renaissance swordmaking?
The presence of Clemes Stam’s name confirms Solingen’s reputation as a leading center for sword production during the Renaissance, supplying weapons to nobility and royalty across Europe.
How did the Allied bombing of World War II impact the preservation of historical artifacts in Jena?
The bombing campaign destroyed the Collegium Jenense, burying centuries of historical relics under rubble. While the subsequent excavations recovered many artifacts, many remained damaged or obscured by corrosion.
What types of materials were used to create the sword’s inlay?
The inscription on the sword was created using approximately 0.6 mm thick copper sheets, individually inlaid into the blade steel.
