A collage composed of magazine articles and pictures A collage (From the French: coller, to glue) is a work of art, primarily in the visual arts, made from an assemblage of different forms, thus creating a new whole. Use of this technique made its dramatic appearance among oil paintings in the early 20th century as an art form of groundbreaking novelty. Techniques of collage were first used at the time of the invention of paper in China around 200 BC. The use of collage, however, remained very limited until the 10th century in Japan, when calligraphers began to apply glued paper, using texts on surfaces, when writing their poems.
