Akhnaten is an opera in three acts based on the life and religious convictions of the Egyptian pharaoh Akhenaten (Amenhotep IV), written by the American composer Philip Glass in 1983. The libretto is by Philip Glass in association with Shalom Goldman, Robert Israel, Richard Riddell, and Jerome Robbins. According to the composer, this work is the culmination of a trilogy including his two other biographical operas, Einstein on the Beach (about Albert Einstein) and Satyagraha (about Mahatma Gandhi). These three people were all driven by an inner vision which altered the age in which they lived: Einstein in science, Gandhi in politics, and Akhnaten in religion.
The text, taken from original sources, is generally sung in the original languages, linked together with the commentary of a narrator in the language of the audience. Egyptian texts of the period are taken from a poem of Akhenaten himself, from the Book of the Dead, and from extracts of decrees and letters from the Amarna Period, the seventeen-year period of Akhenaten's rule. Other portions are in Akkadian and Biblical Hebrew. Akhnaten's Hymn to the Sun is sung in the language of the audience.
