In her ground-breaking new study, Katie Bugyis offers a new history of communities of Benedictine nuns in England from 900 to 1225. By applying innovative paleographical, codicological, and textual analyses to their surviving liturgical books, Bugyis recovers a treasure trove of unexamined evidence for understanding these women's lives and the liturgical and pastoral ministries they performed. She examines the duties and responsibilities of their chief monastic officers—abbesses, prioresses, cantors, and sacristans—highlighting three of the ministries vital to their practice-liturgically reading the gospel, hearing confessions, and offering intercessory prayers for others. Where previous scholarship has argued that the various reforms of the central Middle Ages effectively relegated nuns to complete dependency on the sacramental ministrations of priests, Bugyis shows that, in fact, these women continued to exercise primary control over their spiritual care. Essential to this argument is the discovery that the production of the liturgical books used in these communities was carried out by female scribes, copyists, correctors, and creators of texts, attesting to the agency and creativity that nuns exercised in the care they extended to themselves and those who sought their hospitality, counsel, instruction, healing, forgiveness, and intercession.
