One famous one can be The Scream by Edvard Munch. In the painting the person screaming is portrayed as alone. When looking closely at the picture everything else is in pairs. The two people on the bridge and the two boats in the water. The sky gives an eerie feeling of loneliness. I believe this is best suited for isolation.
a lot of Edward Hoppers work shows this
