To avoid further damage to the manuscript, the research team at the art museum has had to be extremely selective in the techniques they used to see the original writing.

Sometimes original art works appear questionable or inauthentic because they've had so many restorers add touch-up layers to cover up damage, damage from the paint having deteriorated over time.

Nearly everyone who goes to see the original will already be familiar with it from reproductions, but they accept that fine art is more rewardingly viewed in its original form.
