I consider psychoanalytic approaches to myth and the role of mythos (myth) and logos (reason) in Ancient Greece. Myths are sacred narratives that are in constant flux and interpreted by storytellers. Reason tries to establish the truth. Following a discussion of Freud's visit to the Acropolis and his use of the Oedipal myth, Freudian, Jungian and philosophical interpretations of myths are explored. The research of Otto Rank is addressed in the context of his allegiance to Freud and his subsequent break from the father of psychoanalysis. The myth of Prometheus and its links to creativity are presented. Rank's identification of the Promethean complex is reviewed. Existential questions of mortality and immortality are examined in view of the Greek charge to “know thyself”
