The Gallo-Roman Dodecahedron 2-4 Century AD

The Roman Dodecahedron or Gallo-Roman Dodecahedron has long been an object of great mystery. It is a small, hollow object made of bronze or (less commonly) stone. Geometrically, it has 12 flat faces, with each face being pentagonal, decorated with a number of knobs at each of the corners of the pentagon, and having a circular hole of varying diameters connecting to the hollow centre.
