Carl Jung developed the concepts of the collective unconscious and archetypes. Archetypes are universal symbols that are shared across cultures and literature, buried deep in our collective unconscious. Archetypal criticism examines literature for these archetypes. Some common archetypes include characters like the hero, mentor, mother, father; natural symbols like the sun, fire, water; colors; and situations involving quests, journeys, initiation, creation and destruction. When analyzing works, critics look for these recurring archetypal patterns and symbols to understand how the work connects with deep unconscious meanings.
