Knock Ninney and Lough Erne from Bellisle, County Fermanagh, Ireland Thomas Roberts (1748-1777)

The picture has something of this: water, landscape, lake, river, reflection, tree, beach, sunset, sky, nature, dawn, sea, outdoors, sun, summer, seashore, boat, mountain.
Perhaps it’s a painting of a man and a woman standing on a hill overlooking a lake with a sailboat in the distance and a distant mountain range.
