Characterization of Roman mural paintings from the archaeological site of Cercadilla (Cordoba, Spain)

This paper is focused on the characterization on roman mural paintings from the archaeological site of Cercadilla (Córdoba, Spain). The mural paintings were located in a thermal complex that belonged to a Roman palace complex from tetrarchy era. White mural paintings with red vertical and horizontal edges decorations were studied. Several tecniques were used to study the mural paintings: such as colorimetry, macrophotography, optical microscopy, scanning electron microscopy, micro X-ray diffraction, X-ray fluorescence. The results allowed us to determine the composition of materials. In addition, the conservation condition of the mural paintings and the weathering forms were studied
