In the room the women come and go
Talking of Michelangelo.
The repetition of this stanza may hold truth about poet or the protagonist. It may simply reveal Eliot's admiration towards the renaissance art, which is unlikely. However, it may also reveal Prufrock's inability to make an impact upon women, even simply as a conversational topic. It also aids in the development of mystery towards the reader. What is in the room? Why do the women consistently talk of Michelangelo? How does this relate to Prufrock's love story? These question are all designated to drive the reader further into the poem.
