The project was a collaboration between NMD, SMK where CATS was responsible for the coordination of the research part. The goal of the project was to describe the context of Jais Nielsen’s frescoes in two interlacing parts: Art historical and technical research in painting techniques. The projects were disseminated as a publication in 2016, showing the results of the two research areas in close relation to each other. Besides the art historical part, the publication holds a chapter of technical research and beautifully illustrated results from the technical analysis.
