Several of Sylvia Plath¡¦s poems are associated with the term ¡§Gothic¡¨ by critics. By examining how some conventional Gothic literary devices are used and how the feeling of terror is evoked in Plath¡¦s poetry, I shall try to prove the close correspondence between the Gothic literature and Sylvia Plath¡¦s poetry in this thesis. Then, I shall proceed to assert Plath¡¦s orthodoxy in the Gothic literature and discuss her uniqueness in the Gothic tradition.
