Freud’s intense faith in Jung, a man he had called the “Joshua” to his Moses, and whom he declared would be his successor at a time when psychoanalysis needed a “Christ,” ended in a hermeneutic battle over the Prophet Jonah. This chapter explores how the biblical story of Jonah became the site for working out the differentiation between the Viennese school and Zurich school of psychoanalysis. I argue that the forgotten Jonah trail is worth recovering because Freud’s repudiation of the Biblical hermeneutics surrounding the myth of Jonah largely determined the end of Freud and Jung’s collaboration and, at the same time, influenced Freud’s subsequent attitude to and writings on Biblical prophets. Freud’s taciturn, oppositional, and hitherto unanalyzed discursive relationship with the prophet Jonah sheds new light on psychoanalytic literature on Biblical myth, its reception, and even its consequent influence on the movement after 1913.
