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.

  • When I first saw them I immediately thought it was for tents, where you'd put poles into the holes. But I don't think it's right.

    The knobbles on each corner have to have a purpose. I wonder if there's someway they could be used for cooking.

    Perhaps it's for measuring the diameter of sticks, say for arrows, spears, defensive things, tent poles, etc. where a lot would be made as needed.

    Or to measure corks to put into various amphorae.

  • A measuring device is my number one guess too, yet it isn’t a fully satisfactory answer.

    I was thinking it might be a handy thing to attach by a string to your waist to use for counting out nails. Though the knobs would seem to suggest a different purpose.
