That map looks exactly what I would expect it to look like if it was passed on from master to apprentice metalworker as part of a graduating project. These wouldn't have been products sold to customers and traded, they would have been symbols that the individuals had achieved mastery within a specific lineage of artisans restricted to that region. Almost all knowledge was communicated via oral means because scribes were very expensive and most people were illiterate - there's zero reason to expect a wide distribution throughout the empire.

I think metalworking also has the longest history of sophisticated development in current day Northern Europe. The dispersion on the map I think re-enforces both that history and the notion of a portfolio piece.

Ok but that means there would be more such objects, for every level before mastery right? And also such objects would be much more rare. Imagine all the objects that have been found and melted down during the last 2000 years. For us to have found over 100 of these so far is already an indication that it was a lot more common than an apprentice piece.

  > Ok but that means there would be more such objects, for every level before mastery right? What levels of mastery? Roman historians didn't write much about the ins and outs of their metalworking industry so we don't know how intricate the process was but apprentices graduating is rather universal (their teachers get tired of them or die eventually, after all). Besides, just because it's an "apprentice piece" doesn't mean that it's made by an amateur, but by a skilled artisan to prove they're ready to go out on their own. > And also such objects would be much more rare.

    But you can't really compare any artifact with a metal object, metal was valuable and often melted down. The ones we know about were the ones not found by battlefield scavengers and other opportunists. Even gravediggers would take metal objects and melt them down.

      The bulk of artifacts that survive to this day are pottery, jewelry, and metal Roman coins. Two of those three categories were mostly metal objects that could have been melted down but weren't. Collections of Ancient Roman artifacts are full of metal objects that are orders of magnitude more common than these dodecahedrons. We have many more examples of Roman weapons made up of much more valuable metals that survived.

  “Ok but that means there would be more such objects, for every level before mastery right?” If bronze is expensive, then poor quality versions could simply be melted down to raw material. I like this idea. And I struggle to imagine the scenario, because it seems like it would also have social aspects which we can’t know without written testimony. If the metal is expensive, how is to valued compared to other goods? In the modern world we have tons of stuff, but to what degree is this the same in the ancient Roman world? Who pays it’s cost? If you’re an apprentice could you afford to keep it—especially if you’re not very good (haha).
