ABSTRACT

In 2014, a painting attributed to the seventeenth century Dutch artist Jan Ruyscher appeared on the art market. Despite a prestigious career, Ruyscher, who possibly was a pupil of Rembrandt and Hercules Seghers, vanished from art history after his death and was only rediscovered in the 1930s. In this research paper, the combination of multiple analytical techniques ranging from radiocarbon dating of the support material to multispectral imaging and spectroscopic analyses (XRF, SEM-EDS, FTIR and Raman) of the pictorial layer offers a comprehensive analysis of the object. Radiocarbon analyses of the wooden panel indicated that the tree was probably cut down in the mid-eighteenth century, whereas spectroscopic analyses pinpointed the twentieth century as a timeframe for the application of the pictorial layers. The applied methodology sheds new light on the story of the object itself. The painting was created at the earliest in the 1930s possibly as a consequence of the rediscovery of Ruyscher, and the deliberate use of an aged panel supports an intent to deceive and hence classifies the object as a forgery. The painting under study was furthermore compared with artworks of renowned forgers in an attempt to identify the forger in disguise.

摘要

2014 年，一幅归属于 17 世纪荷兰艺术家 Jan Ruyscher 的画作出现在艺术市场上。尽管有声望的事业，但可能是伦勃朗和赫拉克勒斯·西格斯 (Hercules Seghers) 的学生的 Ruyscher 在他去世后从艺术史上消失了，直到 1930 年代才被重新发现。在本研究论文中，从支撑材料的放射性碳测年到图像层的多光谱成像和光谱分析（XRF、SEM-EDS、FTIR 和拉曼）等多种分析技术的组合提供了对物体的全面分析。木板的放射性碳分析表明，这棵树可能在 18 世纪中叶被砍伐，而光谱分析则指出 20 世纪是应用图层的时间框架。应用的方法为物体本身的故事提供了新的视角。这幅画最早创作于 1930 年代，可能是重新发现 Ruyscher 的结果，故意使用陈旧的面板支持了欺骗的意图，因此将对象归类为赝品。进一步将研究中的画作与著名伪造者的艺术品进行比较，以试图识别伪装的伪造者。
