The aim of this paper is to reconsider the current knowledge of the life and career of Nakhtmin, who was one of the most important individuals in Akhmim at the end of the 18 th Dynasty, as high priest of Min and Isis in that city and overseer of works for King Ay. Through this new analysis, as well as the rediscovery of a little known relief from his tomb, it is possible to give a more detailed account of his career and his family. In a second part, a close study of Nakhtmin's monuments leads to the new hypothesis that the location of his tomb is in Abydos rather than in Akhmim and therefore to the possibility that there was a memorial temple of Ay not only in the Theban area but also in Abydos 1.
