Stelae "U", Athon's Sun-hymn

The Boundary Stelae of Akhenaten are a group of royal monuments in Upper Egypt. They are carved into the cliffs surrounding the area of Akhetaten, or the Horizon of Aten, which demarcates the limits of the site. The Pharaoh Akhenaten commissioned the construction of Akhetaten in year five of his reign during the New Kingdom. It served as a sacred space for the god Aten in an uninhabited location roughly halfway between Memphis and Thebes at today's Tell El-Amarna. The boundary stelae include the foundation decree of Akhetaten along with later additions to the text, which delineate the boundaries and describe the purpose of the site and its founding by the Pharaoh. Total of sixteen stelae have been discovered around the area. According to Barry Kemp, the Pharaoh Akhenaten did not “conceive of Akhetaten as a city, but as a tract of sacred land”.
