Ancient graffiti are texts, but they are texts that exist within a phys- ical environment. We have designed the Ancient Graffiti Project (AGP) to provide a richer understanding of these handwrien in- scriptions from the first century AD in their archaeological context. Interactive maps allow a user to retrieve and analyze all the graffiti in a particular location. ese and other tools, from filters that refine searches to brief descriptions and translations to explain the content of these writings, have been designed to reach multiple audiences, including scholars, students, and interested members of the public. We discuss how we have designed AGP from its incep- tion to be integrated within and interoperable with the Epigraphic Database Roma. e spatial and physical context of graffiti also allows us to link with other spatially oriented digital projects on the ancient world, including the ancient gazeeer Pleiades.

Graffiti are highly individual- ized and heterogeneous in content, format, handwriting, and ex- pression; therefore, multiple factors hinder aempts at studying ancient graffiti collectively and holistically. e Ancient Graffiti Project (hp://ancientgraffiti.org) has been designed: 1) to provide a scholarly resource for the study of graffiti by providing accurate, comprehensive, and up-to-date critical editions of each inscription; 2) to lower the barriers to the study of ancient graffiti and everyday Latin for non-expert communities, including high school students; and 3) to facilitate new avenues of research through digital tools, a user-friendly interface, and a digital resource that is interoperable and integrated within leading digital humanities initiatives. As a born-digital project, AGP is designed to offer ample illus- tration and rich contextual data for each inscription. Many graffiti are deteriorating rapidly as the wall plaster upon which they were wrien remains exposed to the elements. We have therefore begun a program of fieldwork, surveying and recording the ancient graffiti that still survive to document each inscription as fully as possible before it disappears. is paper presents our design and implementation of the An- cient Graffiti Project (AGP). AGP unites data from the Epigraphic Database Roma (edition of text and metadata, which our team pre- pares for EDR) with additional metadata specific to this class of inscriptions, which we are collecting from our fieldwork. In Section 2 of this paper, we describe the motivation for de- veloping the Ancient Graffiti Project, including the limitations of current epigraphic databases and the opportunities presented by a new digital resource focused on ancient graffiti. In Sections 3 and 4, we outline the methodology we have employed in constructing AGP and discuss how we enhance the epigraphic data presented in EDR with graffiti-specific metadata. e Ancient Graffiti Project architecture is described in Section 5, while the features of the user interface are documented in Section 6. Section 7 offers our reflec- tions on the current state of the Ancient Graffiti Project prototype and discusses our plans for future development. 2 MOTIVATION FOR THE PROJECT e concept and design for the Ancient Graffiti Project arose from work with the Epigraphic Database Roma (EDR). e aim of EDR (www.edr-edr.it) is to re-edit, digitize, and make publicly available the ancient inscriptions of Italy from the archaic period up to the seventh century AD. Launched in 1999, EDR now contains more than 81,000 inscriptions. While a great majority of these inscrip- tions were carved into stone, EDR was designed to incorporate other inscribed material as well, including wooden tablets, silver rings, and ancient graffiti scratched on walls [3, 6]. 163
