Why this word is great

PASTICCIO — [Noun] A work of art, music, or literature that imitates or combines elements from various sources, often as a deliberate homage or a falsified composition. From Italian pasticcio ("pie, medley"), via Vulgar Latin pastīcium ("pasty, pie"), its roots in Late Latin pasta ("paste") evoke the kneading together of borrowed fragments. Unlike "pastiche" (which suggests a harmonious tribute) or "collage" (which celebrates visible seams), pasticcio is either a sly forgery or a gleeful scramble—the 18th-century opera stitched together from popular arias, the counterfeit Vermeer painted with meticulous reverence, or the apocryphal letter cobbled from an author’s phrases. It is the art of deception, or the deception of art.

noun

A medley; an olio.“On our first entrance into the palace, which is a pasticcio of Saracenic, Conventual, and Grecian architecture, I was much taken with the principal front of the inner-court; a piece of as good Morisco work as any I had yet seen.”
An artwork that directly imitates the work of another artist or artists.
A falsified work of art, such as a vase or statue made up of parts of original works, with missing parts supplied.
