Abstract

A preliminary investigation into the painting technique and colour palette used in the “Posa della Prima Pietra” canvas by Ismaele Teglio Milla (1853) was carried out in this study. The main goal was to evaluate the presence of preparatory drawings or pentimenti and to spectroscopically characterize the materials used in the artwork. For these purposes, a micro- and non-invasive multi-analytical approach was employed using the following techniques: Multi-Spectral Imaging (MSI), portable X-Ray Fluorescence (XRF), Scanning Electron Microscopy with Energy Dispersive X-ray spectroscopy (SEM-EDX), Attenuated Total Reflection Fourier-Transform Infrared spectroscopy (ATR-FTIR) and Visible Reflectance Spectroscopy (Vis-RS). The results highlighted several pentimenti and other changes made by the artist, along with the identification of most of the colour palette and the components of the preparatory layer.
