Restoration of a Parmigianino's fresco: a micro-Raman investigation of the pictorial surface

摘要

We report on a Raman study performed on sub-miilimetric sized samples taken from the surface of a fresco painted in 1522-24 by Parmigianino (Girolamo Francesco Maria Mazzola, 1503-1540) in the second Chapel of the S. Giovanni Evangelista Church in Parma, Italy, whose restoration has been recently fully completed. The "palette" of pigments used by the artist has been established. X-ray micro-fluorescence measurements confirm the results obtained by the micro -Raman technique.
