Murder in the Cathedral is a play by T.S. Eliot about the murder of Archbishop Thomas Becket in 1170 AD. The play takes place in Canterbury Cathedral, where, like the chorus in a Greek tragedy, a chorus provides commentary about the action in the play. Becket learns of his imminent martyrdom and is tempted by various rewards as well as the glory of martyrdom itself. In the end, Becket is killed by knights sent by the king, who believes that he has been disloyal.
