The Aten, the sun-disk, is first referred to as a deity in The Story of Sinuhe from the 12th dynasty,[REF] in which the deceased king is described as rising as god to the heavens and uniting with the sun-disk, the divine body merging with its maker.[REF]
The full title of Akhenaten's god was "Ra-Horakhty who rejoices in the horizon, in his Name as the Light which is in the sun disc."
