Pharaoh Amenhotep IV recorded details of a Sed-festival event in his new temple complex dedicated to the Aten at Karnak. Blocks from the temple buildings which were re-used after the death of Amenhotep IV, were examined and photographed by the Akhenaten Temple Project between 1966 and 1977 in an attempt to analyse, with the aid of the computer, scenes carved on the blocks known as the Akhenaten 'talatat'.
