Johan Thomas Lundbye (1818-48) – A Danish Coast. View from Kitnæs by the Roskilde Fjord Kobenhavn (SMK) National Gallery of Denmark

The picture has something of this: water, landscape, seashore, outdoors, mountain, beach, rock, sea, nature, sky, daylight, scenic, ocean, sunset, hill, island, tree, river.
Perhaps it’s a painting of a rocky coast with people on the shore and in the distance there is a body of water and a hill with trees on it.
