Scientists have carried out the first multidisciplinary investigation of skeletal remains traditionally identified as those of Saint Theobald of Provins, an 11th-century French nobleman who gave up his privileged life to become a hermit and pilgrim. Their findings suggest the identification is plausible — and have helped researchers recreate the face of the man whose bones have been venerated for centuries.
The remains are preserved in the Church of San Giovanni Battista in Badia Polesine, northern Italy, where they have long been associated with Saint Theobald of Provins. Born in 1033, Theobald belonged to a noble family in Champagne but rejected aristocratic life in favour of voluntary poverty, pilgrimage and religious contemplation.
A new study published in the International Journal of Osteoarchaeology brings together physical anthropology, palaeopathology, genetics, radiocarbon dating and three-dimensional facial reconstruction to examine whether the remains could genuinely belong to the medieval saint.
Who was Saint Theobald?

Theobald was born in Provins, in what is now France, and abandoned the life expected of a young aristocrat to pursue an ascetic existence. He lived as a hermit in the region of Luxembourg before undertaking pilgrimages that took him to Santiago de Compostela and Rome.
He eventually settled near Vicenza in northern Italy. According to historical sources, Theobald died in 1066 at the age of 33. His reputation for holiness was already well established, and he was canonised just seven years later, in 1073.
His remains were eventually transferred to the Abbey of Vangadizza at Badia Polesine, where devotion to the saint became particularly important. After the abbey was suppressed during the Napoleonic period, the relics were moved to the nearby Church of San Giovanni Battista, where they remain today.
Do the bones belong to Saint Theobald?
Six views showing craniofacial and mandibular alterations in the remains attributed to Saint Theobald. The images show severe loss of bone around the teeth (a), porous changes to the hard palate (b), alterations around the nasal opening and a small lesion beneath the right eye (c), porosity of the sphenoid bone (d), new bone formation affecting the lower jaw (e), and porosity of the nasal bones (f). Some of these changes are compatible with leprosy, although they are not considered diagnostic of the disease. Image from Carrara et al., International Journal of Osteoarchaeology (2026), CC BY 4.0.
When Italian researchers examined the skeleton, one of their first findings provided an intriguing match with the historical record. The remains belonged to an adult male who died between approximately 30 and 35 years of age. This fits remarkably well with the traditional account that Theobald died at 33.
Radiocarbon dating provided another important piece of evidence. Analysis of a tooth root produced a calibrated date of AD 988–1163 at 95 per cent confidence. That range comfortably encompasses Theobald’s lifetime of 1033–1066.
The researchers nevertheless stop short of declaring that the identification has been proven. Instead, they conclude that the anthropological evidence, historical documentation and radiocarbon dating make the traditional attribution plausible.
Did Saint Theobald suffer from leprosy?

The bones may also provide clues about the illness that affected Theobald near the end of his life. Researchers identified several abnormalities in the skull, including changes to the nasal region, palate and jaw. Some of these features can occur in people suffering from multibacillary leprosy, a chronic infection caused by Mycobacterium leprae.
However, the evidence is far from conclusive. Many of the skeletal changes are not unique to leprosy, while parts of the hands and feet that can provide important evidence for the disease have not survived.
Genetic testing also failed to detect DNA from Mycobacterium leprae. The researchers therefore consider leprosy a possibility rather than a diagnosis, noting that other chronic infectious diseases could have produced some of the same skeletal changes.
Reconstructing a medieval saint’s face
Perhaps the most striking result of the project is a three-dimensional reconstruction of the face associated with the remains. Researchers created a high-resolution 3D model of the skull and used 52 soft-tissue depth markers to approximate the individual’s facial structure. The reconstruction was deliberately based on the anatomy of the skull rather than attempting to reproduce changes caused by the possible disease.
There are limits to what the reconstruction can reveal. Genetic analysis did not provide enough information to establish characteristics such as pigmentation. The man’s skin tone, eye colour, hair and beard therefore remain hypothetical rather than scientifically determined.
The facial reconstruction was first publicly presented in Badia Polesine in 2020, following an examination of the relics in 2019. Hundreds of digital photographs of the skull taken during that investigation provided the basis for reconstructing its three-dimensional form.
The newly published research now places that reconstruction within a much broader scientific examination of the remains.
The evidence cannot establish beyond doubt that the man whose face has been reconstructed really is Saint Theobald. Yet his sex and age at death fit the historical accounts, while radiocarbon dating places him firmly within the correct period. Together, the results strengthen the possibility that the bones preserved at Badia Polesine belong to the 11th-century hermit who has been venerated there for centuries.
