In no other epoch were artists in the Netherlands so productive, the demand for art so great as during the age of Rembrandt. New genres were born, the art market and the profession of art dealer emerged, exceptional masterpieces that still inspire us today were created. This documentary sets out on the trail of an era in which business and art entered into a marriage for the first time. How did such a flourishing period for art come about? What art-historical innovations do we owe to this period and what significance does it have for our view of and approach to art today?
