Pushmi-pullyu is a living metaphor for the Amphisbaena
The amphisbaena had a twin head, that is one at the tail end as well, as though it were not enough for drawing from the origin of art to the real end of painting.
Raw emotion, in place of the patient description of the real world.
Images still think that their job is to convince the reader of how elegant and cool the art is behind the riddle.
If authenticity is the first step toward originality, pushmi-pullyu is facing hard times with inauthentic metaphors. The pushmi-pullyu often behave in ways that reinforce authenticity.
