The method of Marxist hermeneutics has been developed by the work of, primarily, Walter Benjamin and Fredric Jameson. Benjamin outlines his theory of the allegory in his study "Ursprung des deutschen Trauerspiels" ("Trauerspiel" literally means "mourning play" but is often translated as "tragic drama"). Fredric Jameson draws on Biblical hermeneutics, Ernst Bloch, and the work of Northrop Frye, to advance his theory of Marxist hermeneutics in his influential "The Political Unconscious". Jameson's Marxist hermeneutics is outlined in the first chapter of the book, titled "On Interpretation" Jameson re-interprets (and secularizes) the fourfold system (or four levels) of Biblical exegesis (literal; moral; allegorical; anagogical) to relate interpretation to the Mode of Production, and eventually, history.
