BBC News ran a report today on this 15th century treasure, saying the UK has put a temporary export ban on the Renaissance bronze roundel.
The report described the Manuan roundel as being about 42cm (16.5inches in diameter), depicting Vulcan and his wife Venus – the goddess of love. Venus is holding her son Cupid, while turning towards her lover Mars, the god of war.
Seemingly no one is sure who designed the roundel or who it was produced for. For some of the answers, watch this space during the coming week!
