Question

Suppose a writer sees a painting in a museum and decides to write a poem based on the painting. Why would it be valuable for works on the same subject to exist in different mediums?

Answer 1

    If there are different mediums on one subject, it seems more popular hense the human brain would natural like it more. As well as if it is on different mediums, it can get to people faster like if one person only like poems, they could get into the painting via the painting. I hope this helps. ;)
