From ancient times, through the Middle Ages, to the Renaissance and into the modern world, artists have learned from each other, from books and from exhibitions, appropriating and building on other artists’ works. Today, each new advance in computer technology has facilitated the appropriation and transformation of a work or idea into new creations. The author discusses different ways to appropriate ideas, compositions and palettes as sources for new imagery. She provides background relating to her computer-generated works based on well-known artworks, along with examples of some Masters’ use of appropriation in their own art.
