A graffito, in an archaeological context, is a deliberate mark made by scratching or engraving on a large surface such as a wall. The marks may form an image or writing. The term is not usually used of the engraved decoration on small objects such as bones, which make up a large part of the Art of the Upper Paleolithic, but might be used of the engraved images, usually of animals, that are commonly found in caves, though much less well known than the cave paintings of the same period; often the two are found in the same caves. In archaeology, the term may or may not include the more common modern sense of an "unauthorized" addition to a building or monument. Sgraffito, a decorative technique of partially scratching off a top layer of plaster or some other material to reveal a differently colored material beneath, is also sometimes known as "graffito".
Modern knowledge of the history of Ancient Egypt was originally derived from inscriptions, literature,, pharaonic historical records, and reliefs, from temple statements, from and numerous individual objects whether pharaonic or for the Egyptian citizenry. Twentieth century developments led to finding less common sources of information indicating the intricacies of the interrelationships of the pharaoh, his appointees, and the citizenry. Three minor sources have helped link the major pieces of interrelationships in Ancient Egypt: ostraca, scarab artifacts, and numerous temple, quarry, etc. sources have helped fill in minor pieces of the complex dealings in Ancient Egypt. The reliefs, and writings with the reliefs, are often supplemented with a graffito, often in hieratic and discovered in locations not commonly seen, like a doorjamb, hallway, entranceway, or the side or reverse of an object.
The original "Rotas Square" was later made into the 'Sator Square'.
"Sator square"
The Sator square is a Latin graffito found at numerous sites throughout the Roman Empire and elsewhere. It is a palindrome- which forms a word square that may be read in any direction. See Sator Arepo Tenet Opera Rotas for alternative details. The reason that the palindrome may only be a theory, is because the square may have to be read boustrophedonically. The square reads as follows : The square reads: Sator opera tenet; tenet opera sator, and is approximately: "The Great Sower holds in his hand all works; all works the Great Sower holds in his hand." . Four entry points, one per side, renders the reading of the "Magic Square", the "Sator Square": Right, Left, Upwards, or Downwards. The "Sator Square"- Analysis, Diagrams & "archaeological graffito example": The Sator Square has to begin at "Rotas", so that it can end at "Sator", basically: "The Great Sower",. See:
Large quantities of graffiti have been found in Athens during excavations by the American School of Classical Studies at Athens; nearly 850 were catalogued by Mabel Lang in 1976. These include a variety of different types of graffiti, such as abecedaria, kalos inscriptions, insults, marks of ownership, commercial notations, dedications, Christian inscriptions, messages, lists and pictures. They date from the eighth century BC through to the late Roman period.

Medieval graffiti is a relatively new area of study with the first full-length work being produced in 1967 by Violet Pritchard. The Norfolk Medieval Graffiti Survey was established in 2010 with the aim of undertaking the first large-scale survey of medieval graffiti in the UK. The survey primarily looks at graffiti dating from the fourteenth to seventeenth centuries. Since 2010 a number of other county based surveys have been set up. These include Kent, Suffolk and Surrey. The examples below are from Saint Nicholas, the parish church of Blakeney.
