A View of Theobald’s Park, Hertfordshire John James Chalon (1778-1854)

The picture has something of this: people, landscape, water, dawn, tree, man, sunset, river, child, group, outdoors, cropland, woman, recreation, farming, mountain.
Perhaps it’s a painting of a man standing in a field next to a body of water with cattle grazing in the distance and people on the other side of the water.
