The article focuses on the conservation, materials, and techniques of the unknown Luso-Flemish Master of Lourinhã, analyzing the painting collection of the Santa Casa da Misericórdia da Lourinhã in Portugal. The deteriorated state of some paintings and the poor conditions of the building housing the collection prompted the study. Thermo-hygrometric measurements were conducted, and a multianalytical methodology was employed, including micro-XRD, EDXRF, SEM-EDS, µ-Raman, and µ-FTIR analyses. Infrared photography and reflectography were also used to study the underdrawing technique.
The results were compared with previous studies of the painter’s workshop, revealing distinctions and similarities in materials and techniques used. This analysis methodology aims to contribute to safeguarding and raising community awareness of this endangered cultural heritage. The study involved collaboration between various experts, each responsible for different analytical techniques and results.
Samples were analyzed using optical microscopy, IR photography, and portable EDXRF, among other techniques, to identify painting components and conservation status. The study highlighted the impact of climate conditions on the conservation of artworks, emphasizing the importance of maintaining stable temperature and humidity levels.
Overall, the research provides valuable insights into the artistic processes, materials, and conservation challenges faced by the Master of Lourinhã. It contributes to the preservation of cultural heritage and enhances understanding of the painter’s techniques and creative choices.
