Just published on the free online magazine, Archeomatica, 2, 2014. This paper presents the discovery of these frescoes and their examination performed with technical photography, XRF, and FORS (Fiber Optics Reflectance Spectroscopy). This paper steams from a collaboration that CHSOS has had with University of California San Diego (XRF spectroscopy) and GHT Photonics (FORS spectroscopy) . Then, I need to thank the architect in charge of the conservation intervention which led to their discoveries, Raffaello di Mauro and Don Vittorio Rocca, whose proactive collaboration made possible this study.
