fisn 'n chips literature

English literature is a  fish 'n' chips literature, and I recall a book titled, Tragedy and English Literature, where the author, Richard Dutton, an English professor of English Literature in the University of Lancaster in your county-borough back home, currently in a mid-western university in the USA, who says that English literature is originally alien to tragedy in the European sense, and that all tragic themes in English literary works are not English but are foreign and imported: Hamlet is Danish, Othello Italian, Macbeth Scottish, Spanish Tragedy Spanish, Dr Faustus German, Jew of Malta Maltese, and as for King Lear of England the story is, after all, mythical and therefore not authentically English
