The book that emerged from a bog after 1200 years This is the remarkable story of a medieval book that spent 1200 years in the mud. Around 800 someone had a Book of Psalms made, a portable copy fitted with a leather satchel. The book consisted of sixty sheets of parchment that were carefully filled with handwritten words. Somehow the book ended up in a remote bog at Faddan More in north Tipperary, close to the town of Birr, Ireland. Dropped, perhaps, by the owner?
