The Picture of Dorian Gray help me with homework: Dorian Gray contains many epigrams

Oscar Wilde’s The Picture of Dorian Gray contains many epigrams, most of which are spoken by Lord Henry Wotton. Interestingly, a number of these epigrams reappear in the author’s best-known play, The Importance of Being Earnest, which was written four years later. Choose three epigrams that appear in both works and analyze their contexts. In what ways does Wilde use these witty sayings differently? What do these differences indicate about the alteration in Wilde’s thinking in the period between the two works?
