Real mystery

The Unexplained Roman Dodecahedron

Cast from copper alloy, the Roman dodecahedron is a small hollow object featuring twelve flat pentagonal faces and corner knobs. Each face contains a circular hole of a different diameter leading into its hollow interior. These curious artifacts lack any inscribed numbers or letters and rarely show signs of wear, leaving their true purpose in the ancient Roman world an enduring mystery.
