Amedeo Modigliani (1884–1920) is an artist highly valued by the public. However, his works have been little studied by natural scientists. The project “Modigliani and His Secrets” follows two closely correlated purposes: a better knowledge of the materiality of the works and a better understanding of the studio practice of the artist. The corpus (25 paintings and 3 sculptures, works belonging to French museums) covers the entire work of Modigliani in France from 1908 to 1920. The present article will focus on the beginning of Modigliani's artistic life through the analyses of two paintings dated from 1909 to 1913. The same multi-analytical approach was implemented for each painting. It enables us to determine Modigliani's color palette, but also to unveil pentimenti and previous compositions. Complementary two-dimensional imaging techniques operating in different spectral ranges (MA-XRF, SWIR reflectance hyperspectral, X-ray radiography…) were successful examining Modigliani's masterpieces to reveal the artistic know-how and intentional strategy of the cursed and legendary artist.

MA-XRF 和非侵入性光谱成像技术揭示了莫迪利亚尼的工作室实践

阿梅迪奥·莫迪利亚尼 (Amedeo Modigliani) (1884–1920) 是一位深受公众重视的艺术家。然而，自然科学家很少研究他的作品。“莫迪利亚尼和他的秘密”项目遵循两个密切相关的目的：更好地了解作品的物质性和更好地理解艺术家的工作室实践。语料库（25幅画和3幅雕塑，属于法国博物馆的作品）涵盖了莫迪利亚尼1908年至1920年在法国的全部作品。本文将通过分析莫迪利亚尼1909年至1920年间的两幅画作，聚焦莫迪利亚尼艺术生涯的开始1913. 每幅画都采用了相同的多分析方法。它使我们能够确定莫迪利亚尼的调色板，同时也揭示了五角星和以前的作品。
