In archaeology, rock art is human-made markings placed on natural stone; it is largely synonymous with parietal art. A global phenomenon, rock art is found in many culturally diverse regions of the world. It has been produced in many contexts throughout human history, although the majority of rock art that has been ethnographically recorded has been produced as a part of ritual. Such artworks are often divided into three forms: petroglyphs, which are carved into the rock surface, pictographs, which are painted onto the surface, and earth figures, formed on the ground. The oldest known rock art dates from the Upper Palaeolithic period, having been found in Europe, Australia, Asia and Africa. Archaeologists studying these artworks believe that they likely had magico-religious significance.
'Art cannot be modern.Art is primordially eternal." Modern art represents an evolving set of ideas among a number of painters, sculptors, writers, and performers who - both individually and collectively - sought new approaches to art making. Although modern art began, in retrospect, around 1850 with the arrival of Realism, approaches and styles of art were defined and redefined throughout the twentieth century. Practitioners of each new style were determined to develop a visual language that was both original and representative of the times.
