2. A decorative design, originally representing vine branches or tendrils, at the head of a chapter, of a manuscript or printed book, or in a similar position; hence, by extension, any small picture in a book; hence, also, as such pictures are often without a definite bounding line, any picture, as an engraving, a photograph, or the like, which vanishes gradually at the edge.
Origin: F. Vignette, fr. Vigne a vine. See Vine, and cf. Vinette.
