St Thomas a Becket was murdered by four knights in Canterbury Cathedral in 1170.
Archbishop Becket's story was re-told by T.S. Eliot in a verse drama, Murder in the Cathedral, commissioned for the 1935 Cathedral Festival and performed within yards of the spot where Becket was murdered.
Eliot, who had converted from the Unitarian Church to the Church of England in 1927, treated the story as a latter-day morality play, introducing Four Tempters who challenge Becket's motives, as well as the Four Knights who kill him. It was so well received it went straight on to London and helped Eliot towards winning the 1948 Nobel Prize for Literature.
