Abstract

The oil paintings and “Prayer of Tobias and Sarah” and “The Archangel Raphael reveals himself to Tobi and his son Tobias”, executed by Francesco Bruno at the end of the XVIII century on oval Conservation Science in Cultural Heritage 210 shaped canvas, were investigated by integrated physica-chemical and analytical methodologies in order to obtain scientific data capable of elucidating the state of conservation and the painting technique. Optical (OM) and electronic (SEM-EDS) microscopy, micro-FT-IR spectroscopy, were applied on some microfragments whilst the two whole paintings were analyzed by the non invasive IR reflectografy technique. The reflectography evidenced some pentimenti of author on the canvas “Prayer of Tobias and Sarah”, while invasive analysis made it possible to locate the stratigraphic sequence of each canvas and to characterise the constituent materials.
