The ’Exeter Ordinale’ is a huge ordinal issued by John de Grandisson, bishop of Exeter [1327-69], in 1337; it is edited on the basis of manuscripts that belonged to, and were annotated by, the bishop himself. The compilation marked an important point in medieval study of the liturgy, and the ’Legenda’ [liturgical readings for saints’ days] which it contains are regarded as one of the most important sources for the study of English medieval hagiography, particularly for saints of English origin.
