Firstly, an inventory of all paintings in Ledreborg Palace has been made, including visual analysis of the front and back of the painting, identifying artists’ materials and changes over time. This resulted in factsheets of 450 paintings, including inventory number, preliminary attribution of artist, identification of subject, support, medium, measurements, condition, signature/inscriptions, signs on back, date and artistic relations with known works of art. These files served as starting point for further research, including provenance research. All 450 paintings were photographed by a professional art photographer, made possible by the receival of external funds (Prins Bernhard Cultuurfonds, Kircheiner-Galatiusfonds). A selection of 30 paintings were studied with infrared reflectography on location to identify preliminary sketches or underdrawings as well as compositional changes (pentimenti), and eventual changes over time, in order to investigate how these compositions were copied. Another selection of 30 paintings were studied in more detail with art historical analyses, including research in several archives and documentation collections and literature with a focused on the dispersal of Dutch paintings in Denmark and the differences of practice of the mass-production of paintings between seventeenth-century Flanders and the Dutch Republic
The overall result of this project is an improved understanding of the spread of Netherlandish art. All the paintings will be accessible for researchers and the public through an open-access database with annotated records of these hitherto undocumented and unstudied paintings. Dissemination included also publications, presentations, and the organization of the fourth CATS conference and publication of its contributions in the CATS Proceedings with the title ‘Trading Paintings and Painters’ Materials 1550-1800’. Moreover, the project has provided the young professional researcher with new and essential training to become an expert in the application of both technical instruments and the socio-economical study of Netherlandish paintings.
