Homunculus

This is literally a small human being. This was originally thought to actually exist in sperm cells – so every sperm cell contained a tiny human, which…grew, I guess.

From there, the definition spread a little. Today, it’s often used as a representative of the self when discussing the human brain (see example below).

It’s also used as an analogy/metaphor, but inconsistently. Some examples taken from periodicals (some of which mystify me):

• A homunculus wouldn’t crush your Beetle, but it could do some serious damage under the hood.
• Furthermore, homunculus indicates certain body parts like large lips, hands, feet and genitals, moving Redha to create dances that are not only sensual but also sexual and erotic.
