Mysterious Roman Dodecahedron Returns to the National Civil War Centre

Discovered in June 2023 during a community-led excavation in the village of Norton Disney, Lincolnshire, this dodecahedron is only the 33rd of its kind ever found in Britain, and the first discovered in the Midlands. It is a remarkably well-preserved example, expertly cast and in pristine condition, composed of 75% copper, 7% tin, and 18% lead.

The object gained national attention when it was featured in Episode 4 of BBC 2’s Digging for Britain, hosted by Professor Alice Roberts and is now available for public viewing at the National Civil War Centre, with free entry for all Newark and Sherwood residents until Friday 18 July.

Councillor Rowan Cozens, Deputy Leader and Portfolio Holder for Heritage and Culture at Newark and Sherwood District Council said: “Objects like the Norton Disney Dodecahedron remind us that history isn’t just something we read about, it’s something we live alongside,

“It’s incredible to think that such a mysterious and intricately made object lay hidden for centuries just a few miles from where we are today. I’d encourage everyone, whether you're local or visiting, to come and see this remarkable piece of Roman history up close. It’s a rare chance to experience a real archaeological mystery in person.”

Despite many theories, no one knows exactly what Roman dodecahedra were used for. They don’t appear in Roman texts, vary in size and show no signs of wear. Theories range from surveying tools to religious artifacts, with the current leading hypothesis suggesting a ritual or spiritual function. The Norton Disney example was found carefully placed in a pit alongside 4th-century Roman pottery, suggesting it may have had special significance.

Glyn Hughes, Collections and Exhibitions Manager at the National Civil War Centre adds: “The Norton Disney Dodecahedron is one of the most intriguing Roman artifacts we've had the privilege to display.
 
“Its craftsmanship is exceptional, and its purpose remains a mystery even to experts. That’s what makes it so exciting. It invites everyone to explore, question, and imagine what role it might have played in Roman life.”

The mystery has sparked plenty of creative guesses from museum visitors. Some of the most popular ideas include a Roman spaghetti measurer, a calendar or astronomical device and even a ritual object used in ceremonies.

Visitors are encouraged to share their own theories by posting on social media and tagging the National Civil War Centre @nationalcivilwarcentre with their thoughts.
