This chapter offers close readings of a series of nineteenth- and early twentieth-century play-scripts about the murder of Thomas à Becket in Canterbury Cathedral in 1170, including works by Douglas Jerrold, Arthur Penrhyn Stanley, Alfred Tennyson, and T. S. Eliot. Tracing their performance over 100 years involves the exploration of changing attitudes to the performance of Christian worship and sacrifice on stage and, more broadly, the changing status of the Established Church itself. In the repetitions and variations of Becket’s narrative deployed over time, we can chart changes in the idea of Christian tragedy, renewed appreciation of the communal significance of religious ritual, especially in the revival of the classical chorus, and a growing sense that sacred drama was not just an aberration to be carefully policed and perhaps suppressed, but part of the living fabric of English national drama with a performative future as well as a past.
