The research website janbrueghel.net serves three distinct functions. First, it is a gathering place for information about the Baroque painter Jan Brueghel the Elder. Second, it is a place where a range of people with an interest in this artist, from university-based scholars to museum curators to art dealers and also the owners of paintings, can pool their ideas and untangle the problems raised by Brueghel’s works. Finally, it is a site where new knowledge about the artist can be generated, particularly by studying his workshop practice using the Image Investigation Tool.
