Thermography and shearography are jointly used to analyze the state of conservation of a work of art in the pre-restoration phase. Although the use of non-invasive diagnostic techniques to analyze and monitor artworks is now a common practice, for the first time to the best of our knowledge, shearography technique is used in combination with thermography to analyze paintings. The study focuses on a 18th painting, part of a private collection, that would represent an allegory of the winds, particularly the Greek ones: Boreas, Euro, Noto, Zephyr. Shearography provided surface and subsurface information on the presence of cracks, dis-homogeneities, detachments, surface deformations, while thermo-graphic imaging provide a map of the structural inhomogeneities of the investigated areas, measuring the thermal response, which results altered by canvas defects, thickening of the paint layers or by the presence of nails or glue. The joint use of the two techniques helps us to solve the ambiguities in the interpretation of the single technique achievements. The analysis of the results, obtained by the combination of shearographic and thermographic surveys and by the visual inspection too, allows us to develop interesting hypotheses about the types of issues to discuss with the restorers and to have a more general knowledge of the state of conservation, useful for planning an effective conservation program.
