Vignette

 Vignette comes from the Middle French noun vigne, meaning "vine." In English, the word was first used in the early 17th century for a design or illustration that ran along the blank border of a page, or one that marked the beginning or end of a chapter. Such designs got their name because they often looked like little vines. It wasn't until the late 19th century that vignette began being used for a brief literary sketch or narrative.
