Homunculus

A homunculus (/hoʊˈmʌŋkjᵿləs/; Latin for "little man", plural: "homunculi"; from the masculine diminutive form of homo, "man") is a representation of a small human being. Popularized in sixteenth-century alchemy and nineteenth-century fiction, it has historically referred to the creation of a miniature, fully formed human. The concept has roots in preformationism as well as earlier folklore and alchemic traditions.

References to the homunculus do not appear prior to sixteenth-century alchemical writings; however, alchemists may have been influenced by earlier folk traditions. The mandragora, known in German as Alreona, Alraun or Alraune is one example.

In Liber de imaginibus, Paracelsus however denies that roots shaped like men grow naturally. He attacks dishonest people who carve roots to look like men and sell them as Alraun. He clarifies that the homunculus’ origins are in sperm, and that it is falsely confused with these ideas from necromancy and natural philosophy.

The homunculus has also been compared to the golem of Jewish folklore. Though the specifics outlining the creation of the golem and homunculus are very different, the concepts both metaphorically relate man to the divine, in his construction of life in his own image.

Preformationism, a theory of heredity, claimed that either the egg or the sperm (exactly which was a contentious issue) contained complete preformed individuals called "animalcules". Development was therefore a matter of enlarging this into a fully formed being. The term homunculus was later used in the discussion of conception and birth.

Nicolas Hartsoeker postulated the existence of animalcules in the semen of humans and other animals. This was the beginning of spermists' theory, who held the belief that the sperm was in fact a "little man" that was placed inside a woman for growth into a child. This seemed to them to neatly explain many of the mysteries of conception. It was later pointed out that if the sperm was a homunculus, identical in all but size to an adult, then the homunculus may have sperm of its own. This led to a reductio ad absurdum with a chain of homunculi "all the way down". This was not necessarily considered by spermists a fatal objection however, as it neatly explained how it was that "in Adam" all had sinned: the whole of humanity was already contained in his loins. The spermists' theory also failed to explain why children tend to resemble their mothers as well as their fathers, though some spermists believed that the growing homunculus assimilated maternal characteristics from the womb environment in which they grew.
