This paper presents a combination of noninvasive techniques for the study of superimposed painting stages in The Pentecost, a Mexican Colonial panel painting attributed to Baltasar de Echave Orio (1558 – 1619). The application of reflected hyperspectral imaging (HSI) analysis for mapping the distribution of the pigments in the paint surface and the use of ultraviolet (UV) fluorescence photography and X-ray radiography as complementary imaging techniques provide new insights into the making process of the artwork, its manufacturing and conservation state. For a better understanding of the in situ results gathered, we studied a series of paint mock-up samples created following recipes and studio practices from art treatises. The use of spot analytical methods such as fiber optic reflectance spectroscopy (FORS) and X-ray fluorescence spectroscopy (XRF) allowed for a robust identification of the artist’s materials.

本文介绍了一种非侵入性技术的组合，用于研究五旬节时期的叠加绘画阶段，五旬节时期的墨西哥殖民时期壁画应归功于Baltasar de Echave Orio（1558 – 1619）。反射高光谱成像（HSI）分析在绘制涂料表面颜料分布中的应用以及将紫外线（UV）荧光摄影和X射线放射照相技术用作补充成像技术，可为艺术品的制作过程提供新见解，其制造和保护状态。为了更好地了解原位收集结果后，我们研究了根据艺术论文的配方和工作室实践创建的一系列油漆模型样品。使用诸如光纤反射光谱（FORS）和X射线荧光光谱（XRF）之类的现场分析方法可以对艺术家的材料进行可靠的识别。
