I can't seem to make sense of any of the summary definitions of an archetype according to Jung.
Has a consise, consistent definition been given anywhere?
This may help, hope so :
The second use of archetype comes from the analytical psychology of C. G. Jung (1875-1961) and his theories of the "collective unconscious."5 For Jung, an individual has not only the ego and personal unconscious that Sigmund Freud demonstrated, but also a "collective" unconscious. The "collective" unconscious contains memories, imprints, and modes of human development and behavior conditioned by mankind's entire history. Jung argues that this collective unconscious manifests itself in the affairs of individuals by means of primordial images or patterns of psychic activities, which he calls "archetypes." Among the most important archetypes are God; the savior-redeemer; the hero; the mother; the father; the miraculous child; the shadow; the old wise man; the anima and the animus; and the self. According to Jung, an archetype is a psychic phenomenon, not a visible, tangible thing. Indeed, no one has ever directly confronted an archetype, since archetypal psychic activity introduces into human life only the traces, or "footprints," of the archetype. In Jungian psychology, archetypes manifest themselves by means of concrete, sensuously apprehensible* forms, which he calls "images of the archetypes." Such images are frequently revealed in dreams, folklore, fairy tales, myths, art, literature, and even in popular culture. Strange beasts and myth characters in dreams, heroes and heroines in tales and stories, and figures such as Superman, Tarzan, and Dirty Harry in popular culture are tangible instances of what Jung terms manifest images of archetypal activity.
If we say, for example, "The motion-picture character Shane is the archetype of the hero," then we are probably using the term in its Jungian context. Similarly, if we say, "In World War II Winston Churchill awakened in Englishmen the image of the hero as warrior-crusader," we are likely invoking Jung's theory of archetypes. If, however, we say, "In World War II Winston Churchill became the archetype of the wartime prime minister," we are using tthe term to denote model or prototype.
