Aim.-The aim is to locate the chronological and geographical contexts by scientific analyses of the painted panel "Ragusa Pietà" under debate because of a possible attribution to Michelangelo who is believed to have painted it for Vittoria Colonna.It’s where you listen to the tracks, artists, and albums you already own. Our study contributes new science-based data to an ongoing art historical debate. Obviously, we cannot confirm that Michelangelo himself painted the panel, but our results are coherent with his lifetime (1475-1564) and executive career. These pigments are coherent with the expected period and help to date this panel. According to chemical analysis, the paint's binder is mainly egg tempera with some parts in fat tempera and finish-ings on the sky with azurite in glue tempera over a layer of smalt bound in fat tempera.
Taking the time for wood working and seasoning into account, the terminus post quem for the creation of the painting is between 15. The wooden support is made of spruce and its last tree ring was dendrochronologically dated to 1497. The panel was investigated by means of dendrochronology, wood anatomy and pigment analysis. This paper discusses the results of scientific investigations on a panel painting whose past attribution to Michelangelo has been recently taken again into account. In this study, ToF-SIMS was used to analyze a paint cross section obtained from a painting attributed to Raphael, and another from a painting by the Sienese artist Matteo di Giovanni. Because of this ability to localize the analytical signal to approximately 6 μm or less, the mass spectral information can be used to produce mass-resolved and spatially-resolve images which can be correlated to previous studies of the same samples. This allows for the colocalization of organic and inorganic species in specific layers (e.g. Furthermore, the layered systems that are often encountered in historical paint samples remain intact throughout the analytical procedure.
As an analytical technique, ToF-SIMS avoids the need for derivatization/silylation reagents, with no interference by the presence of pigments. For example, the detection of the ion fragment associated with the amino acid hydroxyproline can be used to confirm the use of animal glue in a paint sample. With recent advances in surface analysis, ToF-SIMS can now be used to identify specific amino acids present in protein-containing materials as well as fatty acids in drying oils. This technique provides high-resolution spatial maps of both inorganic and organic components located within cross-sectional samples collected from works of art. Time-of-flight secondary ion mass spectrometry (ToF-SIMS) is quickly becoming a critical tool in the field of art conservation.
