This article is an outcome of the study, deci-sions, and restoration work undertaken during the inte-grated conservation project of the 16th century paintingsof Funchal’s Cathedral main chapel’s altarpiece, inMadeira Island, Portugal.

Identificationtogether with the cleaning and removal of these coatingswas a delicate and a complex process. Conservatorsalready suspected the existence of overpaints in somepaintings, a close observation of the painted surfaceshowed differences in terms of color, texture, and execu-tion technique in specific areas. Chemical and strati-graphical research together with radiography andhistorical research on primary documental sources pro-vided important clues about the paintings of the previousinterventions and relevant and crucial information for thedecision making
