Hamlet and Oedipus is a study of William Shakespeare's Hamlet in which the title character's inexplicable behaviours are subjected to investigation along psychoanalytic lines. The study was written by Sigmund Freud's colleague and biographer Ernest Jones, following on from Freud's own comments on the play, as expressed to Wilhelm Fliess in 1897, before being published in Chapter V of The Interpretation of Dreams (1899).
