If such manuscripts, written, as in these two cases, exclusively
on paper that was produced a few decades earlier,
are dated on the basis of watermarks, the result will unavoidably
be incorrect. This is because all dating based on
watermarks is undertaken on the premise that the same
type of paper – paper with watermarks that were definitely
made by one and the same wire figure – was used within a
few years.
