New Research Solves 2,000-Year-Old Mystery of Poland’s Lost ‘Princess of Bagicz’
More than a century after a wooden coffin tumbled from an eroding cliff in northwestern Poland, scientists have resolved a dating mystery surrounding the woman buried inside.
But the deeper, more enduring question — who she actually was — remains unanswered, tangled in assumptions that say as much about us as they do about her.
The woman found in that coffin has long been known as the “Princess of Bagicz,” a nickname bestowed not because anyone knows her name, her lineage or her rank, but because of how she was buried.
She was laid to rest on a cowhide inside a log coffin carved from a single oak tree trunk, alongside a bronze pin, a necklace of glass and amber beads, and a pair of bronze bracelets. Her coffin is the only preserved wooden sarcophagus of its kind from the Roman Iron Age.
The label stuck. But the evidence paints a far more complicated portrait — one of a young woman whose bones bore the marks of physical toil, not privilege.
A Wooden Coffin Emerges From the Earth
The coffin was discovered in 1899 in the village of Bagicz, in what is now northwestern Poland, after it fell from an eroding seaside cliff.
It had survived the centuries because it was located in a wet, humid environment — conditions that preserved both the wood and the artifacts inside. The burial was part of a larger cemetery associated with the Wielbark culture, which was related to the Goths.
For decades, the grave goods shaped nearly every assumption made about the woman inside. A 1980s analysis of those artifacts suggested she died between A.D. 110 and 160.
But in 2018, a carbon-dating analysis of her tooth told a strikingly different story, placing her death between 113 B.C. and A.D. 65 — as little as 100 and as much as 300 years earlier.
The conflict was significant enough to throw the entire timeline of her burial into question.
Counting Tree Rings Yields Accurate Results
A team of researchers led by Marta Chmiel-Chrzanowska of the University of Szczecin in Poland turned to dendrochronology — the science of counting tree rings — to resolve the discrepancy. By analyzing the wood of the coffin itself, they could determine when the oak tree used to make it was felled.
Their findings, published Feb. 9 in the journal Archaeometry, provided a clear answer.
“The estimated felling date of the oak used for the coffin was calculated as 120 AD,” the researchers wrote in the study. “It is likely that the coffin was crafted immediately after felling.”
That date of around A.D. 120 aligned with the original grave goods analysis, effectively confirming the earlier timeline. The 2018 tooth-based radiocarbon date, researchers concluded, was likely thrown off by the woman’s diet or water sources — specifically, seafood consumption.
This phenomenon is known as the marine reservoir effect. Carbon stored in oceans is older than carbon on land, which makes marine-consuming organisms appear older than they actually are.
In extreme cases, this effect can skew radiocarbon dates by up to 1,200 years. In humans who ate significant amounts of seafood, the distortion can range from dozens to hundreds of years.
For the woman of Bagicz, it was enough to create a centuries-wide gap that puzzled researchers for years.
The Body Beneath the Beads
The resolution of the dating mystery is a significant scientific achievement. But for those interested in the life this woman actually lived — not the one projected onto her by a glamorous nickname — the most revealing findings came earlier.
According to a 2020 study by Chmiel-Chrzanowska, the woman had osteoarthritis, possibly from work-related overuse — suggesting she was a common worker, not an actual princess. Her estimated age at death was just 25 to 35 years old.
“The woman did not exhibit any paleopathologies that could indicate the cause of death,” Chmiel-Chrzanowska told Live Science in an email.
Whatever took her life, it left no visible trace on her skeleton. What did leave a trace was how she spent her days — not seated in comfort, but engaged in the kind of repetitive physical work that wore down her joints before she reached middle age.
The Search for Answers Continues
No successful DNA analysis has been completed yet on the woman’s remains, but new attempts are planned. Chmiel-Chrzanowska traveled to Warsaw in February for further DNA testing, with researchers aiming to extract genetic material from the skull.
“We will attempt to drill into the skull in such a way as to obtain material from the temporal [skull] bone, without the need to damage it,” Chmiel-Chrzanowska told Live Science.
If successful, DNA analysis could reveal details about the woman’s ancestry, health and possibly her geographic origins — pieces of her identity that no burial artifact can provide.
For now, she remains largely unknown: a young woman who worked hard, who was buried with care, and who has spent more than 1,900 years waiting for someone to look past the beads and the bronze and ask who she really was.
