Keywords:

This work aims to present the material characterization of a polychrome wooden sculpture, which is part of religious imagery from the city of Pelotas, Rio Grande do Sul. Belonging to the Metropolitan Cathedral São Francisco de Paula, the image represents Our Lady of the Rosary and exhibits as its main iconographic technical features the right hand closed to hold the rosary and the left arm positioned to carry the baby Jesus. The research exposes the structural characteristics of the three-dimensional work, a semi-articulated dressed image of “roca” type. Its visual and physicochemical characteristics are addressed through macroscopic imaging and molecular analysis. Photographs obtained under visible light and by fluorescence in the visible range with ultraviolet stimulation, radiographic images, and spectra obtained by infrared absorption spectroscopy. Furthermore, a brief introduction to the concepts of technical art history, heritage science and polychrome wooden sculptures is provided, linking them to an analytical case study.
