These relics were integrated into uniquely made caskets by the enamel workshops of Limoges, this being one of the most outstanding pieces.
Since it was a precious casket made of silver, it was created to bear a relic of Thomas Becket. The casket’s one side, rectangular lower panel, depicts the knights assaulting Becket while he is standing picking up something on the altar on his left. The knight to his right is wearing a short tunic savagely beheads the Archbishop with a long sword, while the other knights draw their swords too.
