A chance find by an amateur metal detectorist has added to a long-running mystery of archaeology, as a fragment of an Ancient Roman dodecahedron has been found in the small town of Kortessem, in Belgium. 

The piece, originally part of a dodecahedron measuring 5-6 centimeters (2–2.36 inches) in size, shows signs of having been repaired in the past, with local archaeologists at the Flanders Heritage Agency suggesting that it may have been broken in some kind of ancient ritual.
