Before Edvard Munch painted his masterpiece “The Scream”, the Krakatoa volcano erupted in 1884, likely resulting in nacreous clouds, mother-of-pearl clouds, or “screaming clouds”. This rare weather phenomenon only manifests at sunset or after dark and appears like thin, rippling waves in very distinct colors. University of Oslo’s Dr.Helene Muri suggests that Munch’s work wasn’t painting extreme psychological anguish but rather, simply crazy clouds, nacreous clouds. For years, art historians understood that the weather conditions depicted in “The Scream” represented existential dread as seen in the man’s expression. Muri further supports her theory with Munch’s diary entries which describe the dark and colorful sky seen in his work.
