street art

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. 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.

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. 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.

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 "graffito", or "sgrafitto," 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."

Street art is art, specifically visual art, developed in public spaces — that is, "in the streets" — though the term usually refers to unsanctioned art, as opposed to government sponsored initiatives. The term can include traditional graffiti artwork, sculpture, stencil graffiti, sticker art, wheatpasting and street poster art, video projection, art intervention, guerrilla art, flash mobbing and street installations. Typically, the term street art or the more specific post-graffiti is used to distinguish contemporary public-space artwork from territorial graffiti, vandalism, and corporate art.

Artists have challenged art by situating it in non-art contexts. ‘Street’ artists do not aspire to change the definition of an artwork, but rather to question the existing environment with its own language. They attempt to have their work communicate with everyday people about socially relevant themes in ways that are informed by esthetic values without being imprisoned by them. John Fekner defines street art as “all art on the street that’s not graffiti.”
