Decoupage is a type of collage usually defined as a craft. It is the process of placing a picture into an object for decoration. Decoupage can involve adding multiple copies of the same image, cut and layered to add apparent depth. The picture is often coated with varnish or some other sealant for protection. In the early part of the 20th century, decoupage, like many other art methods, began experimenting with a less realistic and more abstract style. 20th century artists who produced decoupage works include Pablo Picasso and Henri Matisse. Most famous are Matisse's Blue Nude II. There are many varieties on the traditional technique involving purpose made 'glue' requiring fewer layers (often 5 or 20, depending on the amount of paper involved). Cutouts are also applied under glass or raised to give a three dimensional appearance according to the desire of the decouper. Currently decoupage is a popular handicraft. The craft became known as decoupage in France (from the verb decouper, 'to cut out') as it attained great popularity during the 17th and 18th centuries. Many advanced techniques were developed during this time, and items could take up to a year to complete due to the many coats and sandings applied. Some famous or aristocratic practitioners included Marie Antoinette, Madame de Pompadour, and Beau Brummell. In fact the majority of decoupage enthusiasts attribute the beginning of decoupage to 17th century Venice. However it was known before this time in Asia. The most likely origin of decoupage is thought to be East Siberian funerary art. Nomadic tribes would use cut out felts to decorate the tombs of their deceased. From Siberia, the practice came to China, and by the 12th century, cut out paper was being used to decorate lanterns, windows, boxes and other objects. I the 17th century, Italy, especially in Venice, was at the forefront of trade with the Far East and it is generally thought that it is through these trade links that the cut out paper decorations made their way into Europe. Beauty (also called prettiness, loveliness or comeliness) is a characteristic of a person, animal, place, object, or idea that provides a perceptual experience of pleasure or satisfaction. Beauty is studied as part of aesthetics, sociology, social psychology, and culture. An "ideal beauty" is an entity which is admired, or possesses features widely attributed to beauty in a particular culture, for perfection.[citation needed] The experience of "beauty" often involves the interpretation of some entity as being in balance and harmony with nature, which may lead to feelings of attraction and emotional well-being.[citation needed] Because this can be a subjective experience, it is often said that "beauty is in the eye of the beholder." There is evidence that perceptions of beauty are evolutionarily determined, that things, aspects of people and landscapes considered beautiful are typically found in situations likely to give enhanced survival of the perceiving human's genes. The classical Greek noun for "beauty" was , kallos, and the adjective for "beautiful" was ?, kalos. The Koine Greek word for beautiful was , horaios, an adjective etymologically coming from the word ?, hora, meaning "hour". In Koine Greek, beauty was thus associated with "being of one's hour". Thus, a ripe fruit (of its time) was considered beautiful, whereas a young woman trying to appear older or an older woman trying to appear younger would not be considered beautiful. In Attic Greek, horaios had many meanings, including "youthful" and "ripe old age".
