A Roman dodecahedron or Gallo-Roman dodecahedron is a small hollow object made of copper alloy which has been cast into a regular dodecahedral shape: twelve flat pentagonal faces, each face having a circular hole of varying diameter in the middle, the holes connecting to the hollow center. Roman dodecahedra date from the 2nd to 4th centuries AD and their purpose remains unknown. They rarely show signs of wear, and do not have any inscribed numbers or letters.
i’ve seen this offered as a potential explanation as well as being used for textiles/sewing in some way that i can’t remember
Oh, yeah the raised noduals at the corners would let you pull the fabric taunt while keeping it elevated from the surface and you can reach your hand through the hole to grab your needle (…wait, could you? How big are these things?)
They’re pretty small, turns out.
small enough to poke a needle all the way through, hah! my baseless speculation still holds!
Someone was saying that they were used for knitting gloves, but someone else was saying that’s not true, I forget why
