Interesting idea. I did a search for Latin words that have no known meaning and found this: https://latin.stackexchange.com/questions/4683/what-is-the-most-common-classical-latin-word-that-we-dont-understand https://latin.stackexchange.com/questions/4683/what-is-the-m... which suggests a corslet being stiffened with "pale mountain bronze". Perhaps the "pale mountain bronze" is in the form of a dodecahedron? Then did a search for ancient images of women wearing toga's and found this: https://i.pinimg.com/originals/61/29/74/612974bb3612d3ccf9c98a95f9a58a9c.jpg https://i.pinimg.com/originals/61/29/74/612974bb3612d3ccf9c9... Look at her shoulders. Maybe these dodecahedra were ornamental fasteners for clothing, with the different hole sizes allowing them to be used with different weights of fabric. So perhaps they were a fad fashion adornment for rich women (due to the cost of the precision manufacture). I could see the smaller ones being used as a weight attached to clothing to control the drape and accentuate the figure as well. Pull some cloth through it, tie a knot and it pulls on the cloth in a certain way. A hair ornament would make sense also, with the different sized holes allowing for pulling differing amounts of hair through the holes and knotting the hair to hold the ornament in place.
