A sphinx is a mythical creature with, as a minimum, the body of a lion and a human head.
In Greek tradition, it has the haunches of a lion, sometimes with the wings of a great bird, and the face of a human. It is mythicised as treacherous and merciless. Those who cannot answer its riddle suffer a fate typical in such mythological stories, as they are killed and eaten by this ravenous monster. This deadly version of a sphinx appears in the myth and drama of Oedipus. Unlike the Greek sphinx which was a woman, the Egyptian sphinx is typically shown as a man (an androsphinx). In addition, the Egyptian sphinx was viewed as benevolent, but having a ferocious strength similar to the malevolent Greek version and both were thought of as guardians often flanking the entrances to temples.
In European decorative art, the sphinx enjoyed a major revival during the Renaissance. Later, the sphinx image, something very similar to the original Ancient Egyptian concept, was exported into many other cultures, albeit often interpreted quite differently due to translations of descriptions of the originals and the evolution of the concept in relation to other cultural traditions.
Sphinxes are generally associated with architectural structures such as royal tombs or religious temples. The oldest known sphinx was found near Gobekli Tepe at another site, Nevali Çori, or possibly 120 miles to the east at Kortik Tepe, Turkey, and was dated to 9,500 BCE.
The largest and most famous sphinx is the Great Sphinx of Giza, situated on the Giza Plateau adjacent to the Great Pyramids of Giza on the west bank of the Nile River and facing due east (29°58′31″N 31°08′15″E). The sphinx is located southeast of the pyramids. Although the date of its construction is uncertain, the head of the Great Sphinx now is believed to be that of the pharaoh Khafra.
What names their builders gave to these statues is not known. At the Great Sphinx site, the inscription on a stele by Thutmose IV in 1400 BCE, lists the names of three aspects of the local sun deity of that period, Khepera–Rê–Atum. The inclusion of these figures in tomb and temple complexes quickly became traditional and many pharaohs had their heads carved atop the guardian statues for their tombs to show their close relationship with the powerful solar deity, Sekhmet, a lioness. Other famous Egyptian sphinxes include one bearing the head of the pharaoh Hatshepsut, with her likeness carved in granite, which is now in the Metropolitan Museum of Art in New York, and the alabaster sphinx of Memphis, Memphis, Egypt, currently located within the open-air museum at that site. The theme was expanded to form great avenues of guardian sphinxes lining the approaches to tombs and temples as well as serving as details atop the posts of flights of stairs to very grand complexes. Nine hundred with ram heads, representing Amon, were built in Thebes, where his cult was strongest.
Perhaps the first sphinx in Egypt was one depicting Queen Hetepheres II, of the fourth dynasty that lasted from 2723 BCE to 2563. She was one of the longest-lived members of the royal family of that dynasty.
The Great Sphinx has become an emblem of Egypt, frequently appearing on its stamps, coins, and official documents.
