Mona Lisa annual check-up

Musée du Louvre, FR

Since 2004 an international research group of wood technologists has been given by the Louvre museum the task of analysing the mechanic al situation of the wooden panel on which Leonardo da Vinci painted his “Mona Lisa” possibly between 1503 and 1506. The general purpose of such study was to evaluate the influences that could possibly derive from environmental fluctuations in the showcase where the painting is exhibited as well as outside the showcase for occasional checks, and develop measurements and models to improve its conservation conditions.

La Sainte Trinité couronnant la Vierge Monitoring

Musée Fabre, FR

Since 2016, Cécilia helped to design and set-up the monitoring project of the panel painting ”La Sainte Trinité couronnant la Vierge”, anonymous, 1516. The panel has been monitored before during and after restoration.

Strain measurements during structural conservation treatment and the long-term monitoring of a 17th-century Dutch panel painting

Rijksmuseum Amsterdam, NL

Monitoring the panel painting ”Jacob Wrestling with the Angel” (1639), by Bartholomeus Breenbergh, throughout the entire structural treatment gave consistent information about the behaviour of the panel support under stress and has allowed for individual steps of intervention to be assessed by conservators and wood scientists. Movement of the wooden support after immediate removal of the thinned vertical battens supported the treatment decision to remove the entire cradle.

The Van Mekeren Cabinets, Comparative Study of Indoor Climate Induced Deformation

Rijksmuseum Amsterdam & Amerongen castle, NL

The 17th century cabinets by cabinetmaker Jan van Mekeren (1658-1733), within the collections of the Rijksmuseum and Amerongen castle in the Netherlands, are important case studies because there are great differences in the climate surrounding the cabinets in Amerongen castle and at the Rijksmuseum. As a currently running case study, one of the Van Mekeren cabinets at Amerongen castle and the one at the Rijksmuseum are monitored by several Deformometric Kit -out-of-plan deformation sensors-placed at several spots on both cabinets in order to access reliable comparative measurements. Also the micro-climate inside the cabinets and surrounding the objects is monitored. Moreover, the global mechanical behaviour of the cabinet in Amerongen castle is monitored by fullfield measurement using Digital Image Correlation. By monitoring these two cabinets during two year, substantial information is gained about the effect of the surrounding micro-climate on the mechanical response of the objects.
