An agreement between ENEA and University of Cagliari gave the chance of studying the materials and the technique used by Maestro di Castelsardo, the major artistic figure working in Sardinia during the end of the XV and the early XVI century.

The application of non-destructive techniques (x-ray fluorescence, x radiography and near infrared reflectography) to investigate four paintings by Maestro di Castelsardo gave the possibility to characterize the pigments and the constructive technique used by the painter. Some hypotheses on the latter could be formulated by the authors of this article thanks to the comparison of the data obtained
