The Function of Prepositions in Article

New scanning technology may offer historians the chance to examine rolled-up records rendered otherwise inaccessible due to their extreme fragility. The technique, which produces a 3D digital image of the document without the need to physically unfurl it, has been developed by a team from Cardiff University and Queen Mary, University of London. The parchment is first scanned for the presence of iron, which was commonly used as an ingredient of ink in Europe between the 12th and 19th centuries and can therefore be used to indicate the position of words on a page. This data is then combined with details of the way in which the parchment has been rolled or folded to generate a high-contrast image of the document as it would have appeared in its flat state.

Tudor historian Anna Whitelock said: “Although one cannot help feel a note of sadness that future historians might not have the thrill of handling documents – and imagining those hands that have held them in the past – this is another example of technology making it easier for historians to reach back into the past and to handle the most delicate of documents.”
