The Madonna of San Giorgio alla Costa by Giotto
Thanks to the technology available at the Opificio delle Pietre Dure of Firenze, the painting was analysed during its restoration in great detail, photographed with ultraviolet rays to view its fluorescence and scanned with infrared rays. The image of the painting was therefore broken down electronically, comparisons made and then reconstructed again. The various layers of colour were analysed to examine previous restoration work and cleaning and several mistakes were found, probably due to rather unsophisticated methods. Moreover a special X-ray, unique in its kind, made it possible to view the substratum of the painting.
