There is a view that the Sphinx was built during the "ancient kingdom" of Egypt, and was built by the Pharaoh Kabra of the fourth dynasty (whose ruling period was from 2520 BC to 2494 BC). This is a traditional view of history, which appears in all Egyptology standard textbooks, encyclopedias, archaeological magazines and common scientific documents. These documents all show that the face of the Sphinx was carved according to Kabra's own appearance-that is to say, the face of King Kabra is the face of the Sphinx, which has been considered as a historical fact. For example, Dr. Edwards, a world-renowned archaeologist, said that although the face of the Sphinx has been seriously damaged, "it still makes people feel that it is a portrait of Cabra, not just a symbolic form representing Cabra".
