Rare Roman dodecahedron find from Norton Disney is set to go on show in Lincoln to coincide with festival of history

A rare Roman find which has attracted international attention is set to get on display as part of a history festival.

Thought to date from the third or fourth century, the copper alloy, hollow, 12-sided object was found during an amateur archaeological ‘dig’ in Norton Disney, in summer 2023 — and now gets star billing at the Lincoln Festival of History on Saturday May 4.

It is one of only 33 such dodecahedrons found in Britain, and the first to have been found in the Midlands. It is also one of the largest examples to be found, measuring around 8cm tall and weighing 245g.

Where most other examples are found damaged, or as fragments, the Norton Disney dodecahedron is complete and in remarkable condition after 1,700 years of being buried.

Their purpose has been lost in the mists of time, as there are no references to them in Roman texts or depictions of them. Based on scientific evidence, it is believed they were not practical items, but associated with Roman rituals and religious practice.

The Norton Disney dodecahedron will now be exhibited in its home county for the first time when it goes on display at Lincoln Museum from Saturday 4 May until early September 2024.

This coincides with Lincoln’s first Festival of History over the early May bank holiday weekend from May 4 to 6.

Andrea Martin, exhibitions and interpretations manager at Lincoln Museum, said: “It’s a real pleasure to have the Norton Disney dodecahedron joining us, being on public display for the first time in Lincolnshire, just a stone’s throw from where it was found. And to have the opening of the display coincide with the Lincoln Festival of History is a real coup for local history fans and visitors to the city.

“The whole Festival of History is a chance for residents and visitors alike to discover more about Lincoln’s story and Lincoln Museum is the perfect place to start that journey of discovery.”

Richard Parker, secretary of the North Disney History and Archaeology Group who found the dodecahedron, said: “Despite all the research that has gone into our dodecahedron, and others like it, we are no closer to finding out exactly what it is and what it might have been used for. The mystery that surrounds it has provoked quite a reaction. Our find received worldwide press attention earlier this year and many people have left us messages with varied and somewhat contradictory suggestions about its purpose.

“The dodecahedron is an extremely tactile object and, having been privileged to have handled it after it’s 1,700 year burial, the imagination races when thinking about what the Romans may have used it for. Magic, rituals or religion; we perhaps may never know.

“What we do know is the Norton Disney dodecahedron was found on the top of a hill in a former large pit of some kind. It seems it was deliberately placed there. Why would someone bury an object like this? Did it have religious or ritualistic significance? What else might we find nearby?

“We now have plans in place to return to the same area in June and more fully excavate where we found the dodecahedron. Last year we ran out of time and money, so we hope to discover more clues about why it was placed there and its possible purpose.”

Alongside the dodecahedron display, visitors can ‘meet the Romans’ themselves in the museum’s atrium, where the legion has returned to ‘Lindum Colonia’. The festival also offers chance to explore some of the many other Roman treasures that have been unearthed across the city and county in the archaeology gallery.

The event also features a guided tour of Posterngate, where you can explore the hidden Roman gateway beneath the city streets.
