It is a passive conception of the social reality. It does not express the creativity of the popular classes but their non-creativity. The origin of the movement is in Rauschenberg and Jasper Johns, who are considered as Neo-Dadaists. Painting becomes again something that evokes. The mere fact of taking a real object and to put it in the painting is an instinctive manipulation of reality. Given that it is a urban art the images end capsized in the painting, unite to the matter or giving a phantom appearance.


Optical Art was born in the 1950’s. It is a method of painting concerning the interaction between illusion and picture plane, between understanding and seeing. Op art is a perceptual experience related to how vision functions. It is a dynamic visual art, stemming from a discordant figure-ground relationship that causes the two planes to be in a tense and contradictory juxtaposition. Op Art is created in two primary ways. The first, and best known method, is the creation of effects through the use of pattern and line. Often these paintings are black and white, or otherwise grisaille.
The works are based on the repetition of some elements, mainly lineal, or simple geometric forms and through the colour give to them the appearance of having a third dimension or of being in movement. One of the most famous artist related to this movement is Vasarely.

The American Alexander Calder invented the mobile, consisting of a delicately balanced wire armature from which sculptural elements are suspended. In common with other types of kinetic art, kinetic sculptures have parts that move or that are in motion. The motion of the work can be provided in many ways: mechanically through electricity, steam or clockwork; by utilizing natural phenomena such as wind or wave power; or by relying on the spectator to provide the motion, by doing something such as cranking a handle. Kinetic art encompasses a wide variety of overlapping techniques and styles.

It began in the 1970’s. It is a type of deliberate marking on property that can take the form of pictures, drawings, words or any decorations inscribed on any surface outside walls and sidewalks. Even if graffiti have always existed, young New Yorkers belonging to the black and Puerto Rican communities started adopting tags (signatures made with aerosol sprays).
The first modern identified tagged in New York was Taki, a Greek-American artist. At the same time, the graphs also made their appearance. These were real urban frescoes painted with spray-paint. Futura 2000, Dust and Pink were recognised although their celebrity was limited to the hip-hop culture. Basquiat and Haring started to work in the street and the subway but their work was renowned and reputed. They won instant critical acclaim and attracted the attention of influential art dealers.
The difference between tagging and graffiti is not clear but some say that while tagging is gang-motivated and meant as vandalism or viewed as too vulgar or controversial to have public value, graffiti can be viewed as creative expression, whether charged with political meaning or not.

Artist belonging to this group are De Maria, Heizer and Goldsworthy.

The term 'Arte Povera' was introduced by the Italian art critic and curator, Germano Celant, in 1967. His pioneering texts and a series of key exhibitions provided a collective identity for a number of young Italian artists based in Turin, Milan, Genoa and Rome. They were working in radically new ways, breaking with the past and entering a challenging dialogue with trends in Europe and America. As the Italian miracle of the post-war years collapsed into a chaos of economic and political instability, Arte Povera erupted from within a network of urban cultural activity. Arte Povera described a process of open-ended experimentation. In the wake of the iconoclastic artistic innovations of Italian precursors Lucio Fontana and Piero Manzoni, artists were able to begin from a zero point, working outside formal limitations. Arte Povera therefore denotes not an impoverished art, but an art made without restraints, a laboratory situation in which a theoretical basis was rejected in favour of a complete openness towards materials and processes.
The artists associated with Arte Povera worked in many different ways. They painted, sculpted, took photographs and made performances and installations, creating works of immense physical presence as well as small-scale, ephemeral gestures. They employed materials both ancient and modern, man-made and 'raw', revealing the elemental forces locked within them as well as the fields of energy that surround us. Members of this group are Anselmo, Pistoletto and Metz

There are examples of the Minimalist theory being exercised as early as the 18th century when Goethe constructed an Altar of Good Fortune made simply of a stone sphere and cube. But the 20th century sees the movement come into its own. From the 1920s artists such as Malevich and Duchamp produced works in the Minimalist vein but the movement is known chiefly by its American exponents such as Dan Flavin, Carl Andre, Ellsworth Kelly and Donald Judd who reacted against Abstract Expressionism in their stark canvases, sculptures and installations.
Minimal Art is related to a number of other movements such as Conceptual Art in the way the finished work exists merely to convey a theory, Pop Art in their shared fascination with the impersonal and Land Art in the construction of simple shapes. Minimal Art proved highly successful and has been enormously influential on the development of art in the 20th century. Representative artists are Frank Stella and Ellsword Kelly .
