第十九世纪以前的时间期限是有限的艺术。早期的艺术家只对富有的赞助人或教会这样的机构委托艺术品。在大多数情况下，艺术只限于代表宗教和神话故事。在第十九世纪，艺术的范围被扩大，艺术家开始对人们的艺术，地方，或他们感兴趣的想法，他们的经验。艺术成为现实世界和自我想象的再现。美国艺术家Man Ray considered作为一个抽象画家，是一个艺术创造的绘画、照片、拼贴艺术对象（瑞，1983）。
1924，超现实主义是由Andre Breton出版的第一期“La Ré进化着é阿利斯特”正式成立（Foster，2004，p.190）。根据现代艺术的概念、超现实主义等现代艺术运动是Dada a’substitute，其艺术家关注这场革命开始联系。超现实主义艺术家们探索的自动化和梦想的可能性”（同上，p.123），它是在潜意识中创造的，最初是从西格蒙德·弗洛伊德的理论（Tate Modern）。
现成的马塞尔·杜尚理论是艺术作品，是通过使用普通的人造的物体，然后做一些艺术的变化和修改他们的创造，作为一种药物，被称为“视网膜”艺术。做一些改变，使对象中的一个新面貌可称为成衣。这些都是通过倾斜和签名（喷泉），把钉子上（礼物），通过插入一些机械变化等，然后对象成为艺术品（福斯特，2004）。据Andre Breton，现成的是超现实主义的对象实例（André，1969）。定义“现成品”由马塞尔·杜尚提出，也存在与é布列塔尼和保罗É卢亚德的超现实主义的定义“一个简单的对象被提升到新的高度，达到一个艺术作品的尊严，仅仅选择一个艺术家”（马休斯，J. H. 1985）。杜尚年产不超过20成品艺术工作的对象在他的整个生命。成衣的概念正在改变它的理念贯穿了杜尚的生活（Waldberg，1965页）。大约所有的创造，是超现实主义的概念下做出的令人惊讶的组合，不合理的，不合逻辑的艺术作品，包括对象和艺术在一个相似的地方（schneede，M 1974。）。
The time period before 19th century had a limited scope of the term art. The artists earlier were only commissioned towards artwork by wealthy patrons or institutions like the church. In most of the cases, art was only limited to representing religious and mythological stories. During the 19th century, the dimension of art was widened and artists started to make art about people, places, or ideas of their interest, and their experiences. Art became a representation of the realistic world and self imagination. An American artist Man Ray considered as an abstract painter, worked as an artist creating paintings, photographs, collages and art objects (Ray, 1983).
Readymade Theory (Surrealism)
In 1924, Surrealism was officially established by Andre Breton who publishes the first issue of ‘La Révolution Surréaliste’ (Foster, 2004, p.190). According to the concepts of modern art, Surrealism as a modern art movement which was a‘substitute for Dada’, whose artists drew attention from this revolution and started to associate with it. Surrealist artists were ‘exploring the possibilities of automatism and dreams’ (ibid, p.123), it is about creating in the unconscious mind, theories originally from Sigmund Freud (Tate Modern).
The theory of readymade of Marcel Duchamp signifies the art work that is being created through using ordinary manufactured objects and then making some artistic changes and modifications in them, as a remedy which was called “retinal art”. Making some changes that brings a new look in the object can be called readymade. These is being done through slanting and putting a signature on it (Fountain), putting nails on it (The Gift), through inserting some mechanical changes etc, and then the object becomes an artwork (Foster, 2004). According to Andre Breton, the readymade is an example of surrealist object (André, 1969). The definition of “readymade” proposed by Marcel Duchamp and also exists in André Breton and Paul Éluard’s Surrealism that defines “a simple object is being elevated to a level to reach at the dignity of a work of art by the mere choice of an artist” (Matthews, J. H. 1985). Duchamp yearly produces not more than 20 readymade art work objects in his entire life. The concept of readymade was changing its ides throughout the life of Duchamp (Waldberg, P. 1965). Approximately all the creation that were made under the concept of surrealism was surprising combinations, non sequitur, illogical artworks that includes object and art at a similar place (Schneede, M. U. 1974).
