Roman dodecahedra are one thing of an enigma: there isn’t a 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 plenty 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, because of the period of time and metallic 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 article, the place everybody on website was buzzing with pleasure and disbelief, to coping with all the eye each nationally and internationally. It has been fantastic to witness the curiosity in our discover and the historical past of Norton Disney.
There have been quite a few solutions 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. As a result of excessive stage of talent concerned, some have urged that they have been a approach for a grasp craftsman to exhibit their professional talents.
There isn’t a uniformity within the measurement or form of the dodecahedra discovered up to now, nor of their metallic composition and even within the stage of expertise. In the event that they have been essential objects, we might count on to additionally uncover contextual proof within the archaeological file, akin to depictions in work or mosaics. It does really feel that this object will stay a thriller for a while – which may 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 subject 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 thirty third to be present in England and the primary to be discovered within the Midlands.
There are some things that make this discover significantly particular. First is its measurement, as it’s regarded as one of many largest examples in Britain. Second is the excessive stage of preservation of the article. As Richard Parker, the secretary for the NDAG, defined: “Ours is in absolutely fantastic condition. It is completely undamaged and there is no evidence of any wear at all.”
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 way used to analyse aspect composition, was carried out by archaeometallurgist Gerry McDonnell, an professional prior to now use and manufacturing of metals by people. It revealed that the composition of the article 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 yr will probably be despatched to Newcastle College for some additional scientific evaluation.
The positioning of the discover itself is attention-grabbing. Pottery shards from plenty of the trenches ranged in date from the Iron Age as much as the Roman interval, displaying a protracted, continued use of the land.
There may be additionally a Roman Villa near the positioning that was excavated in 1935. Skeletal stays discovered on the villa counsel that it was occupied within the late Roman interval, and that the villa website was later reused as a burial floor. In 1989, a metallic detectorist found a Romano-British horseman deity figurinewithin the neighborhood of the Roman villa, which is at present housed on the British Museum.
There may be nonetheless a lot to study in regards to the website and the dodecahedron itself. The ditch the place it was discovered was not totally excavated in 2023 attributable to 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 likely be returning to the positioning this June to reopen a few trenches and totally excavate the pit the place the dodecahedron was discovered. This can hopefully present a greater image of precisely what the positioning was used for and why the mysterious dodecahedron was positioned there.
