"We knew we could get some very interesting results from our scientific diagnostics but when we looked under ultra-violet light, all of a sudden all these very faint paintings that were ruined by old restorations took on a new life," said Cecilia Frosinini, co-ordinator of the project.

The works, painted on dry plaster around 1320, have faded over the years. The ultra-violet light techniques will be used with care since the continual use of the light could cause additional damage to the paintings.
