Roman dodecahedra are one thing of an enigma: there isn’t any recognized point out of those 12-sided, hole objects in historic Roman texts or photographs. First found within the 18th century, round 130 dodecahedra have been discovered throughout the Roman Empire, though it’s attention-grabbing that almost all have been present in northern Europe and Britain, and none have been present in Italy.
Dodecahedra are fairly intricate, that includes quite a lot of spherical holes, with knobs framing the holes. It will have taken a really expert craftsman to make them. They’re made out of a copper alloy and would have been fairly costly, as a result of period of time and steel that was used to create them, which provides to their intrigue.

I’m a part of the native archaeology group behind the latest discovery of a Roman dodecahedron in Norton Disney, close to Lincoln. It has been fairly a whirlwind for our group, from the shock on the day of discovering the thing, the place everybody on website was buzzing with pleasure and disbelief, to coping with all the eye each nationally and internationally. It has been great to witness the curiosity in our discover and the historical past of Norton Disney.
There have been quite a few strategies by archaeologists and the general public as to what dodecahedra may have been. Some theorise that they have been spiritual objects, knitting instruments, measuring devices or stress toys. Because of the excessive degree of ability concerned, some have steered that they have been a approach for a grasp craftsman to reveal their skilled talents.
There isn’t any uniformity within the measurement or form of the dodecahedra discovered thus far, nor of their steel composition and even within the degree of workmanship. In the event that they have been vital objects, we might count on to additionally uncover contextual proof within the archaeological file, equivalent to depictions in work or mosaics. It does really feel that this object will stay a thriller for a while – which is likely to be why so many individuals are fascinated by it.
The Norton Disney dodecahedron
In June 2023, the Norton Disney Archaeology Group (NDAG)(of which I’m the treasurer) carried out a area people dig in a area near the village of Norton Disney, Lincolnshire.
4 trenches have been opened, and it was in trench 4 – in what gave the impression to be a big pit – {that a} completely crafted dodecahedron was discovered. It’s the 33rd to be present in England and the primary to be discovered within the Midlands.
There are some things that make this discover notably particular. First is its measurement, as it’s regarded as one of many largest examples in Britain. Second is the excessive degree of preservation of the thing. As Richard Parker, the secretary for the NDAG, defined: “Ours is in completely unbelievable situation. It’s utterly undamaged and there’s no proof of any put on in any respect.”
The dodecahedron has undergone some preliminary evaluation with a view to attempt to present some extra clues about it. A handheld XRF (X-Ray flourescence) evaluation, a method used to analyse component composition, was carried out by archaeometallurgist Gerry McDonnell, an skilled prior to now use and manufacturing of metals by people. It revealed that the composition of the thing was principally a mixture of copper alloy (75%), with tin (7%) and lead (18%).
The Norton Disney dodecahedron measures round 8cm throughout and weighs 245 grams. It has additionally been scanned utilizing a 3D scanner in collaboration with the College of Lincoln, and later this 12 months will probably be despatched to Newcastle College for some additional scientific evaluation.
The location of the discover itself is attention-grabbing. Pottery shards from quite a lot of the trenches ranged in date from the Iron Age as much as the Roman interval, exhibiting an extended, continued use of the land.
There’s additionally a Roman Villa near the location that was excavated in 1935. Skeletal stays discovered on the villa recommend that it was occupied within the late Roman interval, and that the villa website was later reused as a burial floor. In 1989, a steel detectorist found a Romano-British horseman deity figurinewithin the neighborhood of the Roman villa, which is at present housed on the British Museum.
There’s nonetheless a lot to be taught concerning the website and the dodecahedron itself. The ditch the place it was discovered was not totally excavated in 2023 as a result of time and monetary constraints (the NDAG is solely reliant on donations), because it was discovered on the penultimate day of the dig.
However the NDAG will probably be returning to the location this June to reopen a few trenches and totally excavate the pit the place the dodecahedron was discovered. This may hopefully present a greater image of precisely what the location was used for and why the mysterious dodecahedron was positioned there.
