<P> Cave paintings (also known as "parietal art") are painted drawings on cave walls or ceilings, mainly of prehistoric origin, dated to some 40,000 years ago (around 38,000 BCE) in Eurasia . The exact purpose of the Paleolithic cave paintings is not known . Evidence suggests that they were not merely decorations of living areas since the caves in which they have been found do not have signs of ongoing habitation . They are also often located in areas of caves that are not easily accessible . Some theories hold that cave paintings may have been a way of communicating with others, while other theories ascribe a religious or ceremonial purpose to them . The paintings are remarkably similar around the world, with animals being common subjects that give the most impressive images . Humans mainly appear as images of hands, mostly hand stencils made by blowing pigment on a hand held to the wall . </P> <P> The earliest known cave paintings / drawings of animals are at least 35,000 years old and were found in caves in the district of Maros, located in Bantimurung district, South Sulawesi, Indonesia, according to datings announced in 2014 . Previously it was believed that the earliest paintings were in Europe . The earliest figurative paintings in Europe date back to the Aurignacian period, approximately 30,000 to 32,000 years ago, and are found in the Chauvet Cave in France, and in the Coliboaia Cave in Romania . The earliest non-figurative rock art dates back to approximately 40,000 years ago, the date given both to a disk in the El Castillo cave and a hand stencil in Timpuseng cave Sulawesi, Indonesia . There are similar later paintings in Africa, Australia and South America, continuing until recent times in some places, though there is a worldwide tendency for open air rock art to succeed paintings deep in caves . </P> <P> Nearly 340 caves have now been discovered in France and Spain that contain art from prehistoric times . Initially, the age of the paintings had been a contentious issue, since methods like radiocarbon dating can produce misleading results if contaminated by samples of older or newer material, and caves and rocky overhangs (where parietal art is found) are typically littered with debris from many time periods . But subsequent technology has made it possible to date the paintings by sampling the pigment itself and the torch marks on the walls . The choice of subject matter can also indicate chronology . For instance, the reindeer depicted in the Spanish cave of Cueva de las Monedas places the drawings in the last Ice Age . </P>
