It seems there may be a misunderstanding in the question, as "Starry Night" is actually a famous painting by Vincent van Gogh, not Edvard Munch. That said, the purpose of van Gogh's "Starry Night" is generally considered to be primarily for an aesthetic purpose. The painting expresses emotion through the use of color and dynamic brushstrokes, emphasizing the artist's feelings and thoughts, rather than serving a purely utilitarian or historical function.
