摘要：

In this paper, results are reported on the analysis of a fragment of roman fresco, presumably dated from I century A.D.. The analysis of the pigments used in the fresco has been performed using the two complementary techniques of micro-LIBS and micro-Raman spectroscopy. Both the techniques allow for microscopic analysis of the samples: however, while micro-Raman spectroscopy gives information on the surface structure of the pigments and binders used, micro-LIBS gives quantitative information on the elemental composition of them, also allowing for stratigraphic analysis with lateral spatial resolution comparable to the micro-Raman technique. The joint use of mu-LIBS and mu-Raman spectroscopy allows for a complete characterization of the sample, and is particularly useful in cases when one of the techniques is not able to give by itself a clear information on the nature of the pigment under study.
