 This study examined the frescoes painted by the artist Saturnino Gatti in the Church of San Panfillo in Tornempart, Italy. It identified three distinct layers of paint, including a preparatory layer of lime plaster and sand, a pigmented layer applied using the fresco technique, and an additional layer of pigment applied over the top. Two different painting phases were observed in one sample, suggesting that the fresco had been altered at some point. The results provide valuable insight into the history and restoration of the frescoes, as well as the techniques and materials used by Gatti during the late 15th and early 16th centuries.
