What is the purpose of building the Sphinx?

Answers:

• To serve as a sacred guardian of the royal cemetery at Giza, and in later eras (such as fifteen centuries BC), it was associated with sun worship and was given the name “Hoor-em-Akhet” (i.e., Horus on the horizon), transforming into an embodiment of the sun god himself as he protected the rising and setting of the sun over the plateau. The Sphinx was not just a memorial statue, but rather part of an integrated religious and funerary complex. In it, the Pharaohs combined the body of a lion (symbolizing brutal physical strength and control over the desert) with the head of a human (symbolizing wisdom, intelligence, and governance).
