Some paintings may have hidden depictions beneath the visible surface, which can provide valuable insights into the artist's creative process and the genesis of the artwork. Studies have shown that these covered paintings can be revealed through image-based techniques and integrated data processing. This study analyzes an oil painting by Beceri from the mid-16th century depicting the Holy Family, owned by the Uffizi Galleries. During the analysis of the materials, we discovered evidence of pictorial layers beneath the visible scene. To uncover the hidden figuration, we applied a multimodal approach that included microprofilometry, reflectance imaging spectroscopy, macro X-ray fluorescence, and optical coherence tomography. We analyzed the brushstrokes of the hidden painting, visualized the underdrawing, located the painted areas beneath the outermost painting, and quantified the thicknesses of the pictorial layers. The pigments used for the underpainting were identified through cross-analysis of X-ray fluorescence and spectral correlation maps. The underlying pictorial subject, Leda and the Swan, appears to be inspired by a long-lost and replicated work by Michelangelo. This information places Beceri and his production in a more defined context.
一些画作在可见表面之下可能有隐藏的描绘，这可以为艺术家的创作过程和作品的起源提供有价值的见解。研究表明，这些被覆盖的画作可以通过基于图像的技术和综合数据处理来揭示。本研究分析了乌菲齐美术馆收藏的一幅16世纪中叶贝切里创作的描绘圣家族的油画。在对材料进行分析时，我们发现了可见场景之下绘画层次的证据。为了揭示隐藏的图像，我们采用了一种多模态方法，包括微观轮廓测量、反射成像光谱、宏观X射线荧光和光学相干断层扫描。我们分析了隐藏画作的笔触，可视化了底稿，定位了最外层画作之下的绘画区域，并量化了绘画层次的厚度。通过对X射线荧光和光谱相关图的交叉分析，确定了底层绘画所使用的颜料。底层的绘画主题《丽达与天鹅》似乎受到了米开朗基罗一幅失传且被复制的作品的启发。这些信息将贝切里及其作品置于一个更明确的背景之中。
