Focus on Copies by Vincent van Gogh and explain the Copy after Jacob Jordaens.
Van Gogh used Jordaen's subject and composition for his rendition of Cows. A later artist, Edward Hopper, also used Jordaen's Cows as a source of inspiration for his work. The painting is located at the Musée des Beaux-Arts de Lille in France. Jan Hulsker notes that the painting is a color study of an etching Dr. Gachet made of Jordaen's painting.
