This paper reports on the pre and post conservation diagnostics of a 14th century icon, the Virgin with the Child and a Saint, by an unknown author, belonging to the Library of Taormina, Sicily. A set of non‐invasive imaging techniques for the investigation of the small painting was applied before and after the restoration treatment. The methods used included technical photography (UV Fluorescence, UV Reflected, Infrared, Infrared False Color, and Infrared Fluorescence), Infrared Reflectography (IRR), Reflectance Transformation Imaging (RTI) and two spectroscopic imaging techniques, Terahertz Time Domain Imaging (THz‐TDI) and Reflectance Imaging spectroscopy using a Multispectral Imaging system (MSI).
At the end of the investigation, an identification of the palette has been attempted, crossing the results obtained by reflectance spectra analysis with those obtained by the other imaging techniques. An accurate examination of the surface has been performed with Reflectance Transformation Imaging (RTI) and with THz‐TDI to locate cracks, flacking, incisions and material losses. This study is a valid example of the application of non‐invasive imaging methods before and after the conservation treatment of a work of art.
