Recently, in the latest "Digging for Britain" series on the BBC:

https://en.wikipedia.org/wiki/Digging_for_Britain

I discovered the Roman Dodecahedron:

https://en.wikipedia.org/wiki/Roman_dodecahedron

...and I could not help it or I had to model it in POV-Ray! ;-)

Edouard Poor's proximity pattern helped to complete it.

An improved lighting and a different texturing.

Very nice work! I like the first better. It comes close to one of the 
originals:

https://commons.wikimedia.org/wiki/Category:Roman_dodecahedron#/media/File:Schwarzenacker_Pentagondodekaeder1.jpg

One always learn new aspects of the Romans and I have no new idea about 
the purpose of these artefacts. But some of the speculations are very 
amusing...

I could only find the following measures (archived German site):

Unfortunately, the images were not saved by the wayback machine.

Best regards
Michael

Nice one, Thomas!

It seems interest in these things has picked up recently, possibly due to
another one having been found in England
(https://www.livescience.com/archaeology/romans/roman-dodecahedron-uncovered-by-amateur-archaeologists-in-the-uk).
I wonder what they were for? Decoration? One person thought maybe they were used
for weaving glove fingers, but others say such weaving techniques weren't
developed that early... It is a mystery.

Thanks Michael! Correct, but I like to play with different possibilities.

I missed that one somehow. In total, over different sites, I come to a 
range of about 4cm to about 11cm in diameter.

Yes, that one in England was what triggered my sudden activity on the 
matter, :-)

It is typical that ever since these objects, fragmented or not, have 
been found, no satisfying explanation has been reached. The weaving 
glove fingers is one of my favourites ;-)

It is waiting for any remote breakthrough...
