ABSTRACT
The most authoritative primary evidence for the enactments of late medieval liturgies within the Experience of Worship research project came from late medieval written liturgical texts. Those texts can be divided into two broad categories: texts to be recited and chanted, and directions. The principal printed Sarum sources containing the required texts for the enacted Masses are the Missal for the priest and the Gradual for the singers. In the Missal, both texts for recitation and rubrics are found in several different sections. The earliest inventory surviving from Salisbury Cathedral establishes that the vestments, books, linen and vessels for Mass at the high altar were kept elsewhere, probably in either the treasury or sacristy. The resources of the choir at Salisbury Cathedral and the 'new' medieval organ at St Teilo's enabled the selective use of polyphony in all the liturgies.
