Uncovered Researchers from all over the world regularly engage with the books, documents and objects in the collections of Hereford Cathedral. They bring their specialist knowledge and sometimes the latest scientific techniques to give us fresh interpretations and reveal hidden information. This special exhibition, shown within the Mappa Mundi and Chained Library Exhibition, invites you to share the excitement of some of their recent findings. Find out: What the colours on Mappa Mundi and the Hereford Gospels are made of. How fingerprints more than 600 years old might still be able to be identified. How a diagram of everything can fit on one small page.
