## In brief

- Kiel University recovered a near-complete Mycobacterium leprae genome from a boat-grave skeleton with no leprosy bone lesions
- The man died around age 50 in the 5th century AD at Fallward, Germany, buried in a 4m oak boat with a wooden throne and Roman military belt
- His genome-wide ancestry best matches populations from the Roman Danube frontier, about 1,400 km southeast of the burial site
- His leprosy strain sits at the base of phylogenetic branch 4, with the only older known relative a 342–117 BCE Egyptian mummy sample
- Researchers propose he may have been a Roman army veteran or long-distance trader, but say the evidence doesn’t confirm either

The skeleton in grave 265 at Fallward, on Germany’s North Sea coast, has no bone damage anywhere that leprosy normally leaves: no pitting on the nasal bones, no erosion of the small bones of the feet, none of the signature lesions pathologists use to diagnose the disease in old bone. Geneticists at Kiel University’s Institute of Clinical Molecular Biology recovered a near-complete genome of Mycobacterium leprae from that skeleton anyway, at more than 99 percent coverage of the reference genome and a mean sequencing depth of 58-fold, from samples taken from a tooth and a heel bone. The finding, published in a study led by Daniel Myburgh in iScience, is a reminder that absence of lesions is not absence of infection: leprosy can sit in soft tissue for years before it reaches bone, if it ever does, and the bacterium’s DNA outlasts the evidence a skeleton would otherwise show.

Fallward sits in the coastal marshland between the Elbe and Weser rivers, where Iron Age and early medieval communities built their settlements on artificial mounds to escape North Sea storm surges. Excavations there in the 1990s uncovered a cemetery used from the late 3rd century to the late 5th century AD, with roughly 200 cremation burials and 60 inhumation burials. Waterlogged clay in parts of the site preserved wood, textile, fur and plant material that normally rots away within decades, which is why Fallward’s wooden grave goods are unusually well documented for the period.

Grave 265 is the standout among the inhumations. The man in it, who died at roughly 50 years old in the second quarter of the 5th century AD, was buried in an oak boat more than four meters long, laid on a reed mat, with the boat sealed under a roof-like arrangement of wooden panels. Outside the boat, excavators found a decorated chair carved from a single alder log, roughly 65 cm high, dated to around 420 AD and known since as the “Throne from the Marsch”: an object researchers treat as a status marker rather than furniture, as [Arkeonews reported](https://arkeonews.net/1500-year-old-boat-grave-in-germany-reveals-a-wooden-throne-and-roman-links/). A maple stool near his feet carries a carved hunting scene, a dog attacking a deer, and a runic inscription; the motif has parallels in Late Roman decorative art. The grave also held a game board, a bronze basin, a ceramic vessel, fish bones, a box shaped like a waterfowl, and a belt with fittings typical of the Late Roman military. Wear and repair marks on several objects indicate they were used in life, not made for the funeral.

## What the sequencing found

The Ancient DNA Working Group at Kiel’s IKMB, working with Hauke Jöns at the Lower Saxony Institute for Historical Coastal Research, took 12 skeletal samples from 11 individuals at Fallward and shotgun-sequenced them, screening the reads for both human ancestry signal and pathogen DNA. Degradation is the usual bottleneck in work like this: of the 11 people sampled, only three yielded DNA of sufficient quality for population-genetic comparison. Two matched the expected profile for 5th-century northwestern Europe, with close affinity to British Iron Age and early Anglo-Saxon reference populations. The third, grave 265’s occupant, did not.

A model comparing the man’s genome-wide ancestry against ancient reference populations across Europe found its closest match in communities that lived along the Roman Danube frontier during the Roman Iron Age and the Migration Period, a zone covering parts of modern Croatia, Slovenia, Hungary and Serbia. The model’s highest-probability point sits roughly 1,400 km southeast of Fallward. Kiel’s lead author Daniel Myburgh called him, in a university statement reported by [Phys.org](https://phys.org/news/2026-11-boat-burial-reveals-leprosy-strain.html), “the first individual from this group to have been identified in Europe,” meaning the first match to that specific ancestry signature found north of the Alps. The researchers are explicit about the limits of the method: a probability surface is not a place of birth, and the data, they say, cannot pin down a precise geographic origin.

That ancestry result gives the Roman-style military belt a second reading. Late Roman border provinces supplied the empire’s army with foederati, allied warriors recruited under treaty from frontier populations; a man from the Danube limes buried a thousand kilometers from home with Roman-associated grave goods fits that pattern, and regional parallels exist. Late Roman military equipment turns up at several burial grounds in the Elbe-Weser triangle, evidence that the Roman army recruited from the area and that veterans sometimes returned home with Roman kit. But the researchers are careful to list the alternative: the belt could as easily have arrived by trade, inheritance or as war booty, and does not by itself prove the man served in the Roman army. Other evidence in the grave, fish bones, reed mats, a waterfowl-shaped box, and skeletal wear consistent with developed upper-arm muscle, points toward a life spent rowing or fishing rather than marching.

## A genome older than its only known relative

The leprosy genome itself is the more unusual result. Researchers built a phylogenetic tree from 3,124 informative SNP (single-nucleotide polymorphism) positions, comparing 44 ancient M. leprae genomes against 185 modern strains. The Fallward strain, designated G265, sits at the base of phylogenetic branch 4, ancestral to nearly all of the branch’s known diversity worldwide. Only one earlier-branching sample is known: a strain recovered from an Egyptian mummy dated to between 342 and 117 BCE, reported by Neukamm and colleagues in 2020. That makes the roughly 1,500-year-old German sample the second-oldest known representative of a lineage whose next-oldest relative predates it by five to six centuries and was found more than 3,000 km away, in Egypt rather than northern Europe.

That gap does not mean the disease traveled directly from the Nile to the North Sea; the study’s authors do not claim a transmission route, only that the Fallward genome extends the known range of branch 4’s early diversity by both geography and centuries. Leprosy is chronic and slow, with an incubation period that can run into years before clinical signs appear, if they appear at all before bone. The study’s authors say it is more likely the man died of something else; what is clear from the genetic data alone is that he carried the infection, not whether it caused him visible illness, and not what killed him.

Kiel’s researchers frame three non-exclusive possibilities for how a Danube-frontier man with a rare leprosy strain ended up buried in a boat on the German coast: he could have been a Roman army veteran who settled there after service, a trader who made long journeys while carrying an asymptomatic infection, or someone who acquired both the ancestry and the disease through a chain of contacts the current DNA record cannot resolve. The broader pattern at Fallward points the same way. The cemetery’s other two analyzable skeletons carry ancestry signals linked to early Anglo-Saxon and British Iron Age populations, fitting a 5th-century North Sea world of population movement toward Britain that archaeologists have long inferred from material culture and now have a second line of genetic evidence for, without proof that any specific individual at Fallward made that crossing. Fallward itself shrank over the course of the 5th century and was likely abandoned by its end, part of a broader contraction of settlement along the southern North Sea coast in the same period.

The open question is sample size. Three usable genomes out of eleven sampled individuals is not enough to say whether grave 265’s occupant was typical of Fallward or an outlier its community chose to honor with a throne and a boat precisely because he was not. Denser ancient-DNA sampling from Danube frontier cemeteries and from other North Sea boat graves would say whether this kind of long-distance movement, and this strain of leprosy, was routine for Late Antiquity’s margins or a single data point dressed up as a trend.
