Graffiti is the name for images or lettering scratched, scrawled, painted or marked in any manner on property. Graffiti is any type of public markings that may appear in the forms of simple written words to elaborate wall paintings. Graffiti has existed since ancient times, with examples dating back to Ancient Greece and the Roman Empire. In modern times, spray paint, normal paint and markers have become the most commonly used materials. In most countries, defacing property with graffiti without the property owner's consent is considered vandalism, which is punishable by law. Sometimes graffiti is employed to communicate social and political messages. To some, it is an art form worthy of display in galleries and exhibitions; to others it is merely vandalism. Graffiti has since evolved into a pop culture existence often related to underground hip hop music and b-boying creating a lifestyle that remains hidden from the general public. Graffiti is used as a gang signal to mark territory or to serve as an indicator or "tag" for gang-related activity. The controversies that surround graffiti continue to create disagreement amongst city officials/ law enforcement and graffitists looking to display their work in public locations. There are many different types and styles of graffiti and it is a rapidly developing artform whose value is highly contested, being 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 BCE in the form of prehistoric cave paintings and pictographs using tools such as animal bones and pigments. 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 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 BCE to the 4th century CE
