A monochrome cave painting is a picture made with only one colour (usually black) - see, for instance, the monochrome images at Chauvet.
In addition to figure painting and abstract imagery, prehistoric caves are also heavily decorated with painted hand stencils rock art, most of which - according to recent research by Dean Snow of Pennsylvania State University - were made by females, but men and children were also involved.
Some of the best examples of this form of painting are the Gargas Cave Hand Stencils (Haute-Garonne), the Panel of Hand Stencils at Chauvet (Ardeche), and the prints throughout the Cueva de las Manos (Cave of the Hands) in Argentina.
One theory links the evolution of Stone Age art to the arrival of anatomically modern humans in Europe during the period of the Upper Paleolithic.
According to this theory, the development of cave art coincided with the displacement of Neanderthal man by anatomically modern man, starting around 40,000 BCE.
Therefore some of these "cave studios" may be found to be older than originally thought.
This is exactly what happened at Altamira, where the main body of art is Magdalenian (c.15,000 BCE), but recent tests showed that one particular abstract image dates back to the Aurignacian era about 34,000 BCE.The next oldest paintings are those in Chauvet Cave, situated in the Ardeche region of France.They were discovered in 1994, and date from 30,000 BCE.For details of arts & culture during the Pleistocene and Holocene epochs, see: Irish Stone Age Art Mainly megalithic architecture Irish Bronze Age Art Celtic metalwork, tomb-building Irish Iron Age Art La Tene Celtic culture, sculpture The majority of prehistoric cave paintings were figurative and 99 percent of these were of animals.At first, Stone Age artists painted predator animals (lions, rhinoceroses, sabre-toothed felines, bears) almost as often as game animals like bison and reindeer, but from the Solutrean era onwards imagery was dominated by game animals.Third, the edges of the animal's body would be shaded with black or another pigment to increase its three-dimensionality.
