During recent University of Pennsylvania excavations in the tomb of Woseribre Senebkay at South Abydos, we discovered that the burial chamber incorporated a number of limestone blocks deriving from earlier monuments. Three of these inscribed blocks in particular still retain the images and offering texts belonging to a small group of high officials, including the Overseer of Fields, Dedtu. Analysis of the texts upon the blocks demonstrates that the named individuals probably all belonged to the same family, and that their careers spanned the mid-Thirteenth Dynasty. This paper examines the texts and images upon the reused blocks from the tomb of Senebkay in detail, along with other contemporary evidence, in order to ascertain the identities of the people pictured upon them, where the reused blocks originally came from, and of what types of buildings they may once have been part.
