A liturgical drama set to music, reconstructed from a medieval manuscript in the British Museum. The edition presents a version of the work which is both historically accurate and creates a living performance. No polyphony or harmony has been added, but doubling in unison or in octaves is used extensively. There are 15 parts for solo voices (a mixture of sopranos, tenors, baritones, basses) and a choir of sopranos and men's voices. The narration is by W. H. Auden.
