Graffiti and graffito are from the Italian word graffiato ("scratched"). "Graffiti" is applied in art history to works of art produced by scratching a design into a surface. A related term is "sgraffito",[4] which involves scratching through one layer of pigment to reveal another beneath it. This technique was primarily used by potters who would glaze their wares and then scratch a design into it. In ancient times graffiti was carved on walls with a sharp object, although sometimes chalk or coal were used. The word originates from Greek γράφειν — graphein — meaning "to write." Graffiti (singular: graffito; the plural is used as a mass noun) is writing or drawings scribbled, scratched, or sprayed illicitly on a wall or other surface in a public place.[1] Stickers and other adhesives are not considered graffiti, apparently because they are less common. Graffiti ranges from simple written words to elaborate wall paintings, and has existed since ancient times, with examples dating back to Ancient Greece and the Roman Empire.[2] In modern times, paint, particularly spray paint, and marker pens have become the most commonly used graffiti materials. In most countries, marking or painting property without the property owner's consent is considered defacement and vandalism, which is a punishable crime. Graffiti may also express underlying social and political messages and a whole genre of artistic expression is based upon spray paint graffiti styles. Within hip hop culture, graffiti has evolved alongside hip hop music, b-boying, and other elements.[3] Unrelated to hip-hop graffiti, gangs use their own form of graffiti to mark territory or to serve as an indicator of gang-related activities. Controversies that surround graffiti continue to create disagreement amongst city officials/law enforcement and writers who wish to display and appreciate work in public locations. There are many different types and styles of graffiti and it is a rapidly developing art form whose value is highly contested, reviled by many authorities while also subject to protection, sometimes within the same jurisdiction. The term graffiti referred to the inscriptions, figure drawings, etc., found on the walls of ancient sepulchers or ruins, as in the Catacombs of Rome or at Pompeii. Usage of the word has evolved to include any graphics applied to surfaces in a manner that constitutes vandalism. The earliest forms of graffiti date back to 30,000 BC in the form of prehistoric cave paintings and pictographs using tools such as Animal bones and pigments.[5] These illustrations were often placed in ceremonial and sacred locations inside of the caves. The images drawn on the walls showed scenes of animal wildlife and hunting expeditions in most circumstances. This form of graffiti is subject to disagreement[clarification needed Disagreement between whom and concerning what?] considering it is likely that members of prehistoric society endorsed the creation of these illustrations. The only known source of the Safaitic language, a form of proto-Arabic, is from graffiti: inscriptions scratched on to the surface of rocks and boulders in the predominantly basalt desert of southern Syria, eastern Jordan and northern Saudi Arabia. Safaitic dates from the 1st century BC to the 4th century AD. The ancient Romans carved graffiti on walls and monuments, examples of which also survive in Egypt. Graffiti in the classical world had different connotations than it carries in today's society concerning content. Ancient graffiti displayed phrases of love declarations, political rhetoric, and simple words of thought compared to today's popular messages of social and political ideals[7] The eruption of Vesuvius preserved graffiti in Pompeii, including Latin curses, magic spells, declarations of love, alphabets, political slogans and famous literary quotes, providing insight into ancient Roman street life. One inscription gives the address of a woman named Novellia Primigenia of Nuceria, a prostitute, apparently of great beauty, whose services were much in demand. Another shows a phallus accompanied by the text, 'mansueta tene': "Handle with care". Disappointed love also found its way onto walls in antiquity: Quisquis amat. veniat. Veneri volo frangere costas fustibus et lumbos debilitare deae. Si potest illa mihi tenerum pertundere pectus quit ego non possim caput illae frangere fuste? Whoever loves, go to hell. I want to break Venus's ribs with a club and deform her hips. If she can break my tender heart why can't I hit her over the head?
