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.”
