Metaphysics, Psychology and Philosophy have defined the notion of archetype. We will argue that there is another concept, the “anarchetype” which could escape to the centralization and to any pre‑defined structure building on archetypes. Anarchetype belongs to anarchic and unpredictable structures denying center and logos. It could be used to study marginal or non coherent works far beyond occidental pattern. Eschatype is finally analysed. Some structures without any archetype have to draw an internal evolution before building any model (...) or order. If eschatype is not initially known, it finally shows up and exposes explanations, meanings and even a structure. Eschatype may then give birth to a new theme. It finally may be found in other supports or works, structure and archetype. (shrink)
