Abstract Goa Cathedral former altarpiece is one of the oldest set of paintings in India. The seven remaining paintings from the first altarpiece of Goa Cathedral, nowadays in the sacristy, are attributed by some art historians to Master Garcia Fernandes (act. 1514–1565), Portuguese painter from Lisbon workshop. The 16th century was the “Golden age” of Portuguese painting. In this context the Royal Lisbon workshop played a predominant role, where the activity of the painter Garcia Fernandes and his workshop can be distinguished. In this new approach, Goa paintings are being studied and compared with other works in Portuguese territory attributed to this same painter, as St. Bartholomew altarpiece from the chapel of Bartolomeu Joanes in Lisbon Cathedral. The stratigraphic study allowed to compare ground layers, pigments and binders which, were characterized using complementary analytical and imaging techniques: (X-ray Fluorescence spectrometry (XRF), Infrared Reflectography (IRR), Infrared Photography (IRP), Macro Photography (MP), micro-X-ray Diffraction (μ-XRD), Scanning Electron Microscopy with Energy Dispersive Spectroscopy (SEM-EDS), Raman micro-spectroscopy (μ-Raman), Fourier Transform Infrared micro-spectroscopy (μ-FTIR), Pyrolysis gas chromatography mass spectrometry (PY-GC/MS). This work brought a new insight on the techniques and materials used in this Masterpiece and highlighted the conclusion that Goa Cathedral former altarpiece must be a Portuguese production.

关于果阿大教堂前祭坛画的起源：对来自 16 世纪里斯本工作室的葡萄牙画家加西亚费尔南德斯作品的材料和技术评估

摘要果阿大教堂前祭坛画是印度最古老的画作之一。果阿大教堂的第一幅祭坛画中剩余的七幅画作如今收藏在圣器收藏室，一些艺术史学家将其归功于里斯本工作室的葡萄牙画家加西亚·费尔南德斯大师（1514-1565 年）。16世纪是葡萄牙绘画的“黄金时代”。在这种情况下，里斯本皇家工作室发挥了主导作用，可以区分画家加西亚费尔南德斯和他的工作室的活动。在这种新方法中，果阿画作正在研究中，并与葡萄牙领土上属于同一画家的其他作品进行比较，例如里斯本大教堂 Bartolomeu Joanes 教堂的圣巴塞洛缪祭坛画。地层研究允许比较地层、颜料和粘合剂，显微 X 射线衍射 (μ-XRD)、带能量色散光谱的扫描电子显微镜 (SEM-EDS)、显微拉曼光谱 (μ-Raman)、傅里叶变换红外显微光谱 (μ-FTIR)、热解气相色谱质谱 (PY-GC/MS)。这项工作为这件杰作中使用的技术和材料带来了新的见解，并突出了果阿大教堂前祭坛画必须是葡萄牙作品的结论。显微 X 射线衍射 (μ-XRD)、带能量色散光谱的扫描电子显微镜 (SEM-EDS)、显微拉曼光谱 (μ-Raman)、傅里叶变换红外显微光谱 (μ-FTIR)、热解气相色谱质谱 (PY-GC/MS)。这项工作为这件杰作中使用的技术和材料带来了新的见解，并突出了果阿大教堂前祭坛画必须是葡萄牙作品的结论。
