Abstract art is art that does not depict objects in the natural world, but instead uses colour and form in a non-representational way.[1] In the very early 20th century, the term was more often used to describe art, such as Cubist and Futurist art, that depicts real forms in a simplified or rather reduced way—keeping only an allusion to the original natural subject. Such paintings were often claimed to capture something of the depicted objects' immutable intrinsic qualities rather than its external appearance. (See abstraction.) The more precise terms, "non-figurative art," "non-objective art," and "non-representational art" avoid any possible ambiguity.
The term Abstract Art was coined in the 20th century (ca. 1911) to describe a cultural phenomenon that occurred simultaneously throughout western culture. For this reason, it isn't clear who the first Modernist abstract painter was: it could have been Robert Delaunay in Paris; or the American Arthur Dove; the Czech František Kupka; the Russians Wassily Kandinsky or Kasimir Malevich; the Dutch painter Piet Mondrian; Balla in Italy or many others. Rather than an invention of an individual, abstraction in Modernist painting appeared as a cultural phenomenon.
Non-objective art is not an invention of the 20th century — that humans have made non-objective art since they first drew pictures in the dirt. In the Islamic religion the depiction of humans is not allowed, and consequently the Islamic culture developed a high standard of decorative arts. Calligraphy is also a form of non-figurative art.
