It is the largest monolith statue in the world, standing 73.5 metres (241 ft) long, 19.3 metres (63 ft) wide, and 20.22 m (66.34 ft) high. It is the oldest known monumental sculpture, and is commonly believed to have been built by ancient Egyptians of the Old Kingdom during the reign of the Pharaoh Khafra (c. 2558–2532 BC).
The Sphinx against the Pyramid of Khafre
The Sphinx is a monolith carved down into the bedrock of the plateau which also served as the quarry for the pyramids and other monuments in the area. Because of its geological history, the nummulitic limestone of the area consists of layers of widely differing quality offering unequal resistance to erosion, mostly due to wind and windblown sand, which explains the uneven degradation of the body of the Sphinx. The floor of the Sphinx depression and lowest part of the body including the legs is solid, hard rock. Above this, the body of the lion up to its neck is a heterogeneous zone with friable layers that have suffered considerable disintegration. The layer in which the head was sculpted is also much harder.
The Great Sphinx is one of the world's largest and oldest statues but basic facts about it are still subject to debate, such as when it was built, by whom, and for what purpose. These questions have resulted in the popular idea of the "Riddle of the Sphinx", alluding to the original Greek legend of the Riddle of the Sphinx.
Pliny the Elder mentioned the Great Sphinx in his book, Natural History, commenting that the Egyptians looked upon the statue as a "divinity" that has been passed over in silence and "that King Harmais was buried in it".
It is not known by what name the creators called their statue, as the Great Sphinx does not appear in any known inscription of the Old Kingdom, and there are no inscriptions anywhere describing its construction or its original purpose. In the New Kingdom, the Sphinx was called Hor-em-akhet (English: Horus of the Horizon; Hellenized: Harmachis), and the pharaoh Thutmose IV (1401–1391 or 1397–1388 BC) specifically referred to it as such in his Dream Stele.

The commonly used name Sphinx was given to it in classical antiquity, about 2000 years after the commonly accepted date of its construction, by reference to a Greek mythological beast with a lion's body, a woman's head and the wings of an eagle (although, like most Egyptian sphinxes, the Great Sphinx has a man's head and no wings). The English word sphinx comes from the ancient Greek Σφίγξ (transliterated: sphinx), apparently from the verb σφίγγω (transliterated: sphingo / English: to squeeze), after the Greek sphinx who strangled anyone who failed to answer her riddle.
The name may alternatively be a linguistic corruption of the phonetically different ancient Egyptian word Ssp-anx (in Manuel de Codage). This name is given to royal statues of the Fourth dynasty of ancient Egypt (2575–2467 BC), and later in the New Kingdom (c. 1570–1070 BC) to the Great Sphinx more specifically.
Medieval Arab writers, including al-Maqrīzī, call the Sphinx balhib and bilhaw, which suggest a Coptic influence. The modern Egyptian Arabic name is أبو الهول (Abū al Hūl, English: The Terrifying One).
