I have seen people argue that "they are pretty intricate and expensive things to use only for the purposes of knitting gloves. ". To them, I would like to submit my wife's $1100 sewing machine that definitely gets used, and isn't just some weird status symbol among creative types.
My mother has a fascination with Roman Dodecahedra, so I 3D printed her one for Christmas. She hasn't knitted any gloves with them yet. (And may never, but she still likes it and has it sitting on the mantle over the fireplace.)
It's a rope junction, with the different holes for different knots and rope bundles, with the spokes serving as rope bend/end points. Presumably it would get weeded out as the places where it was employed either stopped making use of them, like perhaps the weather fabric roof shielding of the coliseum, or ended up using more specialized means, like for sailing.
My personal idea is that they are objects created both to flex metalworking craftsman skill and in worship of sacred geometry. Ancient peoples ascribed divinity to the harmonies of the universe, especially the harmonies in mathematics like geometry. The fancier looking platonic solids like dodecahedron and icosohedron have almost magical levels of symmetry built in to them making them both aesthetically pleasing complex shapes. The fact they even exist inspires philosophical and even spiritual thoughts. As far as I understand romans had some very impressive archetecture incorporating mathematical ratios almost constantly, archetects and metal workers may very well have needed to worship geometry as a divine aspect in order to achieve such neurotic levels of mathematics in their aesthetic.
My theory is that they had no practical purpose, they were just a trendy knickknack that eventually fell out of fashion. A Roman equivalent of a fidget spinner or something.
In a few thousand years whatever has become of humanity will be digging up fidget spinners and wondering about them in the same way we do with dodecahedrons. It's not as if anyone will have been preserving fidget spinner media for millennia to explain them.
I'm thinking coin sorter. You start by sorting the smallest coins through the littlest holes, and work your way up.
I'm a knitter, and making gloves with it just doesn't compute for me. It's too clumsy, with too many extra steps. They'd be making gloves from fabric or leather.
i saw someone suggest it was for hanging torches and i desperately want to know what the fuck the inside of their mind looks like, and what they think a torch is
