One of Zosimos' texts is about a sequence of dreams related to Alchemy, and presents the proto-science as a much more religious experience. In his dream he first comes to an altar and meets Ion, who calls himself "the priest of inner sanctuaries, and I submit myself to an unendurable torment." Ion then fights and impales Zosimos with a sword, dismembering him "in accordance with the rule of harmony" (referring to the division into four bodies, natures, or elements). He takes the pieces of Zosimos to the altar, and "burned (them) upon the fire of the art, till I perceived by the transformation of the body that I had become spirit." From there, Ion cries blood, and horribly melts into "the opposite of himself, into a mutilated anthroparion"—which Carl Jung perceived as the first concept of the homunculus in alchemical literature.
