In Amarna art, the sun disk with rays ending in hands is the Aten.
The Aten was originally a word for the sun disk, but during the reign of Akhenaten it became the focus of a major religious transformation. Artists represented it as a disk sending out long rays, with many rays ending in human-like hands. These hands often hold or offer ankh signs, visually conveying the Aten’s life-giving power to the royal family.
Unlike traditional Egyptian gods, the Aten was not normally shown as a human or animal-headed figure. Its visible form was the radiant disk itself. Akhenaten presented the Aten as the supreme, and for a time effectively sole, object of official royal worship. The capital Akhetaten, modern Amarna, was established as its principal cult center.
The Aten is sometimes confused with Ra, the older solar god, because both are connected with sunlight. In Amarna theology, however, the Aten was a distinct religious focus. Aten worship and its distinctive imagery declined rapidly after Akhenaten’s death, when traditional cults were restored.
