Even though, nowadays, portable systems have a good performance and provide reliable results, in the present case, the in situ approach failed, and the analysis had to be carried out in the laboratory. The obtained...
Remains of pictorial decorations in a series of six representative megalithic monuments of Brittany (France) and two French stelae have been studied by micro‐Raman spectroscopy for the first time. Fungal colonies on the painted orthostats made it difficult to obtain in situ Raman spectra of the paint components. Nevertheless, paint micro‐specimens studied in the laboratory by micro‐Raman spectroscopy,...
