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 compilationmarked 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.
