This concept is based on the 19th-century engraving of Wagner and Homunculus from Goethe's Faust II (https://en.wikipedia.org/wiki/Homunculus#/media/File:Faust_image_19thcentury.jpg). The 3rd image of in my post. "A homunculus is a representation of a small human being, originally depicted as small statues made out of clay. 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." (Wikipedia, https://en.wikipedia.org/wiki/Homunculus)
