Walk into any hotel, house, office building, museum, art gallery, or any place where there are paintings or photographs hanging on the wall, and chances are that you will see a pastoral landscape.
Looking for protection, food, and water — According to Denis Dutton, a philosopher and the author of The Art Instinct: Beauty, Pleasure, and Human Evolution, this is because of evolution and the Pleistocene era. (see Dutton’s TED talk: http://bit.ly/cIj9uo). Dutton says that this typical landscape scene includes hills, water, trees (that are good for hiding in if a predator comes by), birds and animals, and a path moving through the scene. This is an ideal landscape for humans (protection, water, food).
