Since the very beginnings of the digital humanities, Papyrology has been in the vanguard of the application of information technologies to its own scientific purposes, for both theoretical and practical reasons (the strong awareness towards the problems of human memory and the material ways of preserving it; the need to work with a multifarious and overwhelming amount of different data). After more than thirty years of development, we have now at our disposal the most advanced tools to make papyrological studies more and more effective, and even to create a new conception of "papyrology" and a new model of "edition" of the ancient documents. At this turining point, it is important to build an epistemological framework including all the different expressions of Digital Papyrology, to trace a historical sketch setting the background of the contemporary tools, and to provide a clear overview of the current theoretical and technological trends, so that all the possibilities currently available can be exploited following uniform pathways. The volume represents an innovative attempt to deal with such topics, usually relegated into very quick and general treatments within journal articles or papyrological handbooks.

The ongoing digitisation of the literary papyri (and related technical texts like the medical papyri) is leading to new thoughts on the concept and shape of the "digital critical edition" of ancient documents. First of all, there is the need of representing any textual and paratextual feature as much as possible, and of encoding them in a semantic markup that is very different from a traditional critical edition, based on the mere display of information. Moreover, several new tools allow us to reconsider not only the linguistic dimension of the ancient texts (from exploiting the potentialities of linguistic annotation to a full consideration of language variation as a key to socio-cultural analysis), but also the very concept of philological variation (replacing the mono-authorial view of an reconstructed archetype with a dynamic multitextual model closer to the fluid aspect of the textual transmission). The contributors, experts in the application of digital strategies to the papyrological research, face these issues from their own viewpoints, not without glimpses on parallel fields like Egyptology and Near Eastern studies. The result is a new, original and cross-disciplinary overview of a key issue in the digital humanities.

The volume collects papers presented at the International Conference "Greek Medical Papyri - Text, Context, Hypertext" held at the University of Parma on November 2-4, 2016, as the final event of the ERC project DIGMEDTEXT, aimed primarily at creating an online textual database of the Greek papyri dealing with medicine. The contributions, authored by outstanding papyrologists and historians of the ancient medicine, deal with a variety of topics focused on the papyrological evidence of ancient medical texts and contexts. The first part, devoted to "medical texts", contains some new reflections on important sources such as the Anonymus Londinensis and the Hippocratic corpus, as well as on specific themes like the pharmacological vocabulary, the official medical reports, the medical care in the Roman army. The second part collects papers about the "doctors' context", providing highlights from broader viewpoints like the analysis of the writing supports, the study of the ostraka from the Eastern Desert, the evidence of inscriptions and philosophical texts. The third part is entirely focused on the DIGMEDTEXT project itself: the team members present some relevant key issues raised by the digitisation of the medical papyri.
