Murder in the Cathedral Author:T. S. Eliot From T.S. Eliot's prefaces included in this edition: — "This play was written for production (in an abbreviated form) at the Canterbury Festival, June 1935... — In the second edition a chorus was substituted for the introits which, in the first edition, constituted the opening of Part II. To the third  edition the introits have been added as... more » an appendix, and may be used instead of that chorus in productions of the play. ... I have in Part II reassigned most of the lines formerly attributed to the Fourth Knight. When, as was originally intended, the parts of the Tempters are doubled with those of the Knights, the advantage of these alterations should be obvious.
In this fourth  edition certain further rearrangements and deletions have been made, which have been found advisable by experiment in the course of production."
