Пейзаж с Водопадом Fedor Mikhailovich Matveyev (1758-1826)

The picture has something of this: nature, wood, water, tree, river, outdoors, summer, landscape, leaf, park, grass, fair weather, fall, waterfall, stream, environment, lush, composure.
Perhaps it’s a painting of a river with a man in a boat in the middle of it and trees on both sides of the river and mountains in the distance.
