A rare Roman dodecahedron found in Lincolnshire is going on public display, as speculation continues over what it was used for.
It was unearthed at an archaeological dig at Norton Disney and is one of only 33 such objects found in Britain.
The artefact's true purpose remains a mystery but historian Jonathan Foyle, who's from Lincolnshire, believes it could be connected to astrology and the signs of the zodiac.
The dodecahedron is being exhibited at Lincoln Museum as part of the Lincoln Festival of History.
