Uncovered: The Acta and Works of Cadwgan Our Spring special exhibition ‘Uncovered’ shares secrets recently discovered by some of the researchers who work with our books and documents. Some of this research uses the latest scientific techniques to reveal information which cannot be seen by the naked eye; some of it brings knowledge gained from years of research to the interpretation of a single document. Shaun McGuinness of Bangor University is compiling the first edition of the episcopal acta of the medieval bishops of Bangor as part of his PhD research. Hereford Cathedral holds a copy of an indulgence dating from the 1220s granted by Cadwgan, Bishop of Bangor and a monk of Dore, relating to the building of St Ethelbert’s almshouse and a manuscript containing some of his meditations, a rare survival from the literature of Welsh Cistercian spirituality. The scholarly Cadwgan chose to retire to Dore Abbey in 1236, perhaps to be close to the centre of learning at Hereford Cathedral. Tickets are £8 per person. Booking is essential, and may be made via the cathedral library: 01432 374225/6 or email.
