A 16th century Italian panel painting depicting The Raising of Lazarus was retouched more than once in its history. Some of the overpaint will have to be removed due to their unacceptable aesthetic qualities, faulty plank joints and bad condition of wood. The poorly preserved original paint layer, extensive retouching and damaged support give rise to the question  which particular overpaint  to remove and which to kept in place? With the help of observation in raking light, ultraviolet induced fluorescence photography (UVIFP), infrared radiography (IRR), X ray radiography (XRR), scanning X-ray fluorescence spectroscopy (MA-XRF), energy dispersive X-ray spectroscopy (SEM-EDS) and infrared spectroscopy (FT-IR) the author of the poster will propose the safest course of conservation actions, with the emphasis on the decision which parts of the painting layer should be removed.
