This is actually a historical episode: during the reign of Amenhotep III (1390-1353 BC), worship of the god Aton (or Aten) — a representation of the disk of the sun — was resurrected. This process was carried to its extreme conclusion by his successor, Amenhotep IV, who eventually declared Aton to be the only god, thereby creating one of the earliest known monotheistic religions. The pharaoh even changed his name to Akhenaton, meaning 'Aton is satisfied.' The worship of Aton was centered on the capital city Tell-el-Amarna, and was largely confined to upper classes and the pharaonic court; it did not survive Amenhotep. Under his successor, Tutankhamen (King Tut), traditional religious practices were restored.
