Painting is the practice of applying paint, pigment, color or other medium to a solid surface (called the "matrix" or "support"). The medium is commonly applied to the base with a brush, but other implements, such as knives, sponges, and airbrushes, can be used. In art, the term "painting" describes both the act and the result of the action (the final work is called "a painting"). The support for paintings includes such surfaces as walls, paper, canvas, wood, glass, lacquer, pottery, leaf, copper and concrete, and the painting may incorporate multiple other materials, including sand, clay, paper, plaster, gold leaf, and even whole objects. Painting is an important form of visual art, bringing in elements such as drawing, composition, gesture, narration, and abstraction. Paintings can be naturalistic and representational (as in still life and landscape painting), photographic, abstract, narrative, symbolistic (as in Symbolist art), emotive (as in Expressionism) or political in nature (as in Artivism). A portion of the history of painting in both Eastern and Western art is dominated by religious art. Examples of this kind of painting range from artwork depicting mythological figures on pottery, to Biblical scenes on the Sistine Chapel ceiling, to scenes from the life of Buddha (or other images of Eastern religious origin). History of painting The oldest known paintings are approximately 40,000 years old, found in both the Franco-Cantabrian region in western Europe, and in the caves in the district of Maros (Sulawesi, Indonesia). In November 2018, however, scientists reported the discovery of the then-oldest known figurative art painting, over 40,000 (perhaps as old as 52,000) years old, of an unknown animal, in the cave of Lubang Jeriji Saléh on the Indonesian island of Borneo (Kalimantan). In December 2019, figurative cave paintings depicting pig hunting in the Maros-Pangkep karst in Sulawesi were estimated to be even older, at at least 43,900 years old.
