The term "graffiti" derives from the Greek graphein ("to write"). Graffiti (s. graffito), meaning a drawing or scribbling on a flat surface, originally referred to those marks found on ancient Roman architecture. Although examples of graffiti have been found at such sites as Pompeii, the Domus Aurea of Emperor Nero (AD 54-68) in Rome, Hadrian's Villa at Tivoli and the Maya site of Tikal in Mesoamerica, they are usually associated with 20th-century urban environments.
