Pictorial and textual graffiti have attracted the attention of archaeologists, anthropologists, epigraphists, historians and philologists since the very early stages in the development of humanities as academic disciplines. Such graffiti have been considered as unique testimonies of everyday life in antiquity, otherwise very hard to detect. Moreover, the practice of writing messages and making drawings on any surface available for scratching has been diachronic and surprisingly perennial; if the thousands of graffiti documented in Pompeii can be considered as indicative, then it seems probable that the graffiti phenomenon was as widespread in antiquity as it is in modern times. Recent monographs, such as Langner 2001, Baird and Taylor 2011 and Keegan 2014 have provided a particularly rich body of new data as well as a holistic approach to this particular body of evidence.
