There are several versions of The Scream & Madonna with some copies of each in museum possession. I never 'got' the appeal of The Scream.
I don’t know whether there’s much to it but in the book Krakatoa about the famous eruption in SE Asia in 1883, the author claims that the tsunami and the meteorological event circled the world and impacted Europe and that the painting “The Scream” was an attempt to record that event as observed in Europe.
