Excavations at the site of Tombos at the Third Cataract in Sudan have revealed tumulus graves adjacent to Egyptian-style tombs created during the New Kingdom. These tumuli began near the end of Egypt’s imperial control of Nubia (c. 1300 BCE) and continued into the early Napatan/Third Intermediate Period (1069–750 BCE). Thirty-five tumuli from the site are analyzed in terms of superstructure, substructure, artifacts and furniture, and the individuals buried within. The combined datasets of bioarchaeological observations and mortuary practices provide an opportunity to consider the processes of cultural expression in terms of “Nubian revival” within the context of Egyptian colonial “withdrawal.” Through a theoretically informed approach, the complexity of intercultural interactions during these dynamic sociopolitical times is examined, expanding beyond the Egyptian/Nubia binary. The tumulus graves at Tombos are used to demonstrate that a diverse set of practices were used that transcend these categories. Practices are entangled with multidimensional influences that question what is considered local and foreign. With variations showing similarities and differences of structures and practices found in the region during earlier, contemporary, and later periods, an innovative group of practices is revealed.
