|Abstract: ||Greg´orio Lopes is one of the most famous Portuguese painters of the 15th–16th centuries.
This work is a contribution to the study of his painting technique, specifically addressing the
methodology used in the preparation of ground layers, which has never been carried out previously
with this multianalytical method.
For this purpose characterization of the ground layers of a selection of his paintings was carried
out by micro-Energy Dispersive X-ray Fluorescence spectroscopy (m-EDXRF), micro-X-ray
Diffraction (m-XRD), Scanning Electron Microscopy - Energy Dispersive Spectroscopy (SEMEDS)
and complemented by micro-Raman spectroscopy. This work presents the results obtained
on two altarpieces (c.1544) produced at the same period by this Portuguese artist. Ground layers
are composed mainly of calcium sulfate—anhydrite and gypsum—and other compounds such as
dolomite. Reference samples were prepared to obtain diffraction pattern of different percentage of
gypsum and anhydrite and compared with the results from historical samples.|
