the homunculus into whom Ion is changed devours himself. He spews forth his own flesh and rends himself with his own teeth. The homunculus therefore stands for the uroboros, which devours itself and gives birth to itself
Jung argues that the Zosimian homunculus is symbolically equivalent to the uroboros, making it a figure of self-generating circular transformation prior to psychic differentiation.
