What was a Roman Dodecahedron used for?

Roman dodecahedra have been found in Britain, much of Europe, but not Italy. The context of use is uncertain, but some have been found in areas of military or funerary activity. Others have been discovered in coin hoards, suggesting they were objects of value. Some dodecahedra were found in baths, one was found in a theatre, another on a river bed.

Dodecahedra are usually cast in copper alloy, of varying design, size between around 4cm to 11cm diameter. The holes on each face are of different sizes and decoration varies with circles, lines and dots being common.

To date, the purpose of these objects has eluded archaeologists, but suggestions have included: Measuring device, knitting tool, metal worker practice piece, or less seriously, spaghetti measure.

  • So if they haven’t been found in Italy, from the map, it looks like an army on the move, no paintings or drawings exist showing it as being used for sport or leisure. The small hole lining up with a larger one could be used for measuring distance. I’ve stolen this map from the internet.

  • That map illustrates your theory well. 

    You have made me wonder if the object was used in school geometry classes.

  • If for school then why none in Italy? It has to be something you would need when travelling long distances.
    Looking at the map, some of the finds are practically in straight lines, obviously the Romans were known to travel in straight lines.
    I would think quite high status as they aren’t found in great quantities. If for everyday use, it would be easier and cheaper to carve out of wood.  Rome was founded on The twelve tables of law, also there were twelve main gods and goddesses. ( twelve sides) The calendar didn’t become twelve months until much later. Another possibility is that it was to gauge the size of something for payment.

  • Let us know how you get on with the replica. Would be cool to see if you decide to make it.
