Robert,Hubert – Le jet d’eau du bosquet des muses a Marly-The fountain in the Grove of the muses in Marly Château de Versailles

The picture has something of this: tree, fall, wood, nature, water, outdoors, landscape, mist, park, waterfall, leaf, fog, people, river, summer, scenic, dawn, fair weather.
Perhaps it’s a painting of a group of people in a park with a waterfall in the background and a man and woman standing in the foreground of the painting.
