Aten is an ancient Egyptian deity associated with the sun and light. Represented as a solar disk with rays extending downwards, Aten was worshipped primarily during the reign of Pharaoh Akhenaten, who promoted a form of monotheism centered around this god. Aten's significance marked a shift in religious practices in ancient Egypt, emphasizing the sun's life-giving power. The worship of Aten was part of a broader religious reform initiated by Akhenaten, who moved the capital to Akhetaten (modern-day Amarna). This period, known as the Amarna Period, saw a decline in the traditional polytheistic worship of other gods, such as Amun and Osiris, as Aten became the central figure in the new religious landscape.
