Mimesis as Imitation and Fantasia as Invention
Mimesis, basic theoretical principle in the creation of art. The word is Greek (μῑ́μησις) and means imitation (though in the sense of "re-presentation" rather than of "copying"). Plato and Aristotle spoke of mimesis as the re-presentation of nature.
Fantasia
(1). Music. A musical composition with a free form and often an improvisatory style. | A musical composition based on several familiar tunes.
(2). A thing composed of a mixture of different forms or styles. | Something possessing grotesque, bizarre, or unreal qualities.| The portraits in this quietly powerful exhibition show people who have risked everything for a shot at what the collage offers: a painstaking fantasia of life, liberty and the pursuit of happiness (Christopher Knight, "This artist’s portrait subjects: Fellow asylum seekers in the detention center," latimes.com, 22 June 2019).
