What were the Gallo-Roman dodecahedra for?

Asked 26 Oct 2026 by ·6 answers·0·0 following
Most likely: they were religious or magical objects, used for divination or as symbols of the cosmos, perhaps mounted on…Ahead on the evidence, not yet confirmed. It needs two reviews to be accepted.

Where it stands

Six answers have been proposed. They were religious or magical objects, used for divination or as symbols of the cosmos, perhaps mounted on… leads, with evidence 3 for, 1 against: partly supported by its tests. Five are still possible. Of the two narrower questions under it, none is answered yet.

Why it matters

Some 130 carefully cast objects from four centuries and nine modern countries have no recorded purpose⁠[1]⁠[2]. The rival answers make testable predictions about hole sizes, wear and find contexts.
