Chimaera is a fantastic and metaphorical journey from fetus (when we all are pure and simple) to chimaera; the complicate yet beautiful monster we get to be when we grow up. The human being suffers along all his life, a series of emotional and conductual modifications that lead to self-reeducation of the character, and sometimes, to traumas that change (mutate) the personality creating a new being. The fetus is clean and pure, and is educated to stay that way, educated to tame the creature beneath. But his experiences make him react and learn, making the monster show up in some occasions.
