Note: "Nobody knows its original name. Sphinx is the human-headed lion in ancient Greek mythology; the term likely came into use some 2,000 years after the statue was built. There are hundreds of tombs at Giza with hieroglyphic inscriptions dating back some 4,500 years, but not one mentions the statue. 'The Egyptians didn’t write history,' says James Allen, an Egyptologist at Brown University, 'so we have no solid evidence for what its builders thought the Sphinx was....Certainly something divine, presumably the image of a king, but beyond that is anyone’s guess.' Likewise, the statue’s symbolism is unclear, though inscriptions from the era refer to Ruti, a double lion god that sat at the entrance to the underworld and guarded the horizon where the sun rose and set."
