Double Sphinx Representation on the Dream Stele of Thutmose IV 

Detail from Lepsius’ illustration of the Dream Stele of Thutmose IV (c. 1400 BCE), showing the Great Sphinx depicted in a paired, back-to-back form. This dual representation reflects ancient Egyptian symbolic concepts, such as the eastern and western horizons, associated with the god Aker.
