Two non-destructive techniques, Raman spectroscopy and particle induced x-ray emission spectrometry, were used for a compete connotation of the Salerno Exultet, an illuminated parchment dated back to 13th century. The Salerno Exultet exhibits several areas which have underdone restoration treatments during the years. The complete connotation of this masterpiece was necessary in order to identify and to distinguish the original and the added pigments. Owing to its dimensions, it has been impossible to analyze the Salerno Exultet directly under the microscope of our Micro- Raman spectrometer. We have therefore used optical fibers connected to a three axis micro-positioned measurement head mounted on a large metal frame. PIXE analysis was performed using the portable instrumentation set up by the INFN-LANDIS Laboratory, Catania, Italy. The combination of these two complementary techniques allowed us to reveal a palette formed by lapis-lazuli, cinnabar, verdigris, earths organic lakes and chalk.
