I attended the screening of Hieronymous Bosch: Touched by the Devil at the Yerba Buena Center for the Arts. Hieronymous was a painter that lived during the 1500s in the Netherlands. The documentary followed art historians in their discovery of the motivations and reason of the painter as well as in pursuit of finding new material and the various ways of authenticating it. One interesting feature of the work covered in the film is that apparently Hieronymous had apprentice working along with him, including his family of painters which caused difficulty in the authentication process. In the end when putting on a show the art historians would have to label the art on display as being done in the Studio of Bosch, in order to not deliberately deceive the viewer when the true painter is questionable.
