In order to widen the data about roman polychromy, a sarcophagus belonging to first Christians burials sited in San Callisto complex in Rome was studied. Polychromy and materials were extensively investigated by using in-situ non-invasive techniques (multispectral photography, visible induced luminescence, X-ray fluorescence and fibre optics reflectance spectroscopy). Furthermore small samples taken in secondary areas, with the aim of being less invasive as possible, were analysed in laboratory. Analytical methods include X-ray diffraction (XRD), FT-IR and isotopic analyses to understand polychromy and provenance of marbles.
