Hidden among the collections at Corbridge Roman Town on Hadrian's Wall in Northumberland are a series of dodecahedra (12 sided objects) made of copper alloy that have been puzzling archaeologists since the 18th century. Each one is slightly different, but have common features, with a hole in the centre, decoration and knobs on each corner.
We're joined in the studio by collections curator Dr Frances McIntosh to discuss these rare Roman objects, the theories about their use and the new exhibition they have inspired.
