The Judgement of Paris, 1645-46, National Gallery of Claude Lorrain (1600-1682)

The picture has something of this: tree, people, landscape, outdoors, daylight, group, water, scenic, rock, recreation, sky, nature, mountain, dawn, evening, park.
Perhaps it’s a painting of a group of people and animals in a wooded area with a river in the foreground and a mountain in the background with trees.
