Is the sphinx primary or secondary?

The Sphinx is considered a primary source of historical significance as it is an original monument from ancient Egypt, built during the reign of Pharaoh Khafre around 2500 BCE. It serves as a direct artifact of that time, offering insights into the culture, art, and religious beliefs of ancient Egyptians. Secondary sources, on the other hand, would include analyses, interpretations, or discussions about the Sphinx created by later scholars or historians.
