Also, the dodecahedrons are found in sizes ranging from "4 to 11 cm" in size (according to Wikipedia). That _might_ make sense if there were specialized ones for everything from kids to very large adults, but then...why aren't they found in clusters? You'd expect some towns in the Roman Empire, where gloves were made, to be full of them (in sets, not individual pieces). Instead, they turn up individually and fairly randomly throughout much of the Empire. They often turn up in coin hoards, too, which is an odd place to store a glove-making doodad.
