Myths in which a hero slays a dragon to rescue a princess and then marries her occur in many cultures. Jung believed the story represents a struggle to establish control of unconscious forces, saying �only one who has risked the fight with the dragon and is not overcome by it wins the hoard, the �treasure hard to attain�. . . . he has faced the dark ground of his self and thereby gained himself.� In this example, Brazilian folk hero Prince Oscar rescues the Queen of Waters from a dragon, winning her hand. An example of Brazilian popular culture, such inexpensive pamphlets are sold at fairs and markets.
