This is a beautiful box enameled with a depiction of Thomas a Becket’s murder in Canterbury Cathedral in 1170 and his funeral. It was made in France around 1180 in memorial to him and at one point could have held a relic associated with Thomas. Thomas Becket was Chancellor and Archbishop of Canterbury for Henry II. The two couldn’t get along after Thomas became Archbishop. Supposedly four of Henry’s knights took it upon themselves to get rid of Thomas- as seen on the box.
