The Great Hymn to the Aten is the longest of a number of hymn-poems written to the sun-disk deity Aten. Composed in the middle of the 14th century BC, it is varyingly attributed to the 18th Dynasty Pharaoh Akhenaten or his courtiers, depending on the version, who radically changed traditional forms of Egyptian religion by replacing them with Atenism. The hymn bears a notable resemblance to the biblical Psalm 104.
