The poem’s epigraph is a quotation of Guido da Montefeltro, a particularly manipulative chap who finds a place near the bottom of Dante’s Hell in Inferno. Right away, this epigraph sets off alarm bells that we should be suspicious of everything that shy old Mr. Prufrock says. First he’s trying to lead us down dark, winding streets, then he’s trying to convince us of how decisive he is. Prufrock is one of the most deceptive narrators you’ll ever encounter.
Prufrock purposefully arranges his song to leave out all the parts that would make him look bad.
Although Prufrock says he is not prophet, he’s really the prophet of the so-called "modern man."
