Freud used the term “Oedipus complex”, the name deriving from the homonymous Sophoclean tragedy, to characterize a specific psychological relation between father, mother and child in our modern society: the child, throughout the phallic stage up to the fifth or sixth year of age, shows a strong attraction to the parent of the opposite sex, while at the same time he behaves with jealousy and rivalrous hostility to the parent of the same sex. This complex phenomenon is clearly exposed in the ancient Greek tragedy, some twenty-five centuries before Freud’s codification.
