The Domesday Book and Dead Sea Scrolls

The Domesday Book and Dead Sea Scrolls are written on parchment which is made from animal skin. This skin can degrade and turn into collagen losing the writings for ever. Quentin Cooper meets Professor Tim Weiss, Head of School of Optometry and Vision Sciences, Cardiff University. He is using powerful x-rays to examine incredibly small samples of the texts to see how they are degrading and what can be done to stop it.
