Khufu - Sphinx:
Notice the prominently jutting lower, squarish jaw. Khufu is considered the face on which the Sphinx is modeled.
Now Djedefre and Khafre (Both Khufu's sons);
Notice the headgear (menes) of the Sphinx stylistically is nearly identical to their reigns. This specific style was adopted only for Djedefre and
Khafre's reigns, although the Sphinx's shows some sign of having originally been carved in a style used during Khufu's reign and then recarved by
Khafre in his style.
Visually the Sphinx is matched to the Fourth Dynasty, it was started by Khufu but finished by Khafre. Khafre was, according to some scholars,
attempting to start a "Sphinx cult", which is what the Sphinx temple and enclosure was about, but it died out along with him (he wouldn't be the
first Pharaoh to attempt to take Egyptian religion off on some tangent, and like previous attempts those efforts died along side their Pharaohs)
At any rate, this Web page
contains many of the finer points linking the Sphinx to
Khafre; just some of those pints are:
1. Geological fingerprints - geological layers match between the Sphinx, temple and quarry, offer positive evidence all are one and the same.
2. The "unworshipped cult" - the aforementioned "Sphinx cult" that never took off.
3. Architectural similarity - similarities between Khafre’s Pyramid Temple exist with that of his Sphinx Temple, including plinth bases for massive
Sphinx votive statues that ultimately were never placed (one could argue that the Sphinx itself sitting outside the temple was the ultimate votive
4. The Sphinx quarry - "the lower parts of the Sphinx (and its enclosure or sanctuary) were carved later than Khafre’s pyramid, Pyramid Temple,
causeway, and Valley Temple." (source cited above)
5. The temple terrace - "Khafre’s Valley Temple and the Sphinx Temple are nearly aligned and they sit on the same prepared terrace below the
Sphinx." (source cited above)
6. The causeway drainage channel - the channel predates the Sphinx enclosure, and was 'rendered obsolete' by the enclosure's construction. It is
also a testament to water drainage and site runoff issues present on the plateau.
The source above summarizes the archeological evidence for Khafre’s builders as:
- Completed Khafre’s Valley Temple with its granite casing.
- Built a northern enclosure wall for the Valley Temple that clearly respects the Temple’s granite casing.
- Built the Sphinx Temple, incorporating the northern Valley Temple enclosure wall.
- Built the Sphinx Temple with blocks geologically linked to the Sphinx quarry.
- Abandoned work on the Sphinx Temple and Sphinx quarry shortly before either were completed, indicating they were the last elements to be added to
Finally, it wouldn't matter what previous generation had done to the living rock monument that Khufu-Khafre turned into the Sphinx, since all
previous work/carvings would have been eradicated at that point.
