DENVER (CBS4)– The Denver Zoo helped out the Denver Art Museum on Monday with an examination of a painting completed in 1700.

The zoo provided an X-Ray machine, normally meant for large animals like polar bears, to the art museum so they could learn more about a centuries-old painting.

“A significant portion of the inscription is gone to us, which I still keep holding out that we’ll find some sort of printed reference from an earlier time of what it is, but so far our analytical techniques haven’t been able to tell us anything about that,” said Denver Art Museum Director of Conservation Sarah Melching.

Bank of America’s Art Conservation Project funded the analysis. Once the analysis is finished, the results will help guide conservationists through the restoration process.
