From the Valley of the Kings and the environs of the town-site of Deir el-Medina comes the most extensive body of documentation available for the study of a single ancient Egyptian community, illuminating the life-world of the workmen who carved out and decorated the royal tombs of the New Kingdom pharaohs as well as the workmen’s families and those who supported and administered them. Dating this material precisely is a tricky business, since most of the documents, particularly ostraca (limestone flakes or potsherds), lack specific regnal year dates (the standard dating system for ancient Egyptian documents) and few specify the reign of a particular king even when the regnal year date is present. Dating thus relies on a comparative methodology utilising prosopographical information on the workmen themselves. Drawing inspiration from the pioneering work of Jac J. Janssen, this volume attempts to provide comparative datings for 78 ostraca (and papyri) from the late XIXth dynasty.
