Colossi of Memnon is a statue and colossus in Egypt, Africa. UNESCO World Heritage List: Ancient Thebes with its Necropolis gives its chronology as “c. 1390-1352 BCE, reign of Amenhotep III.” Its height is listed as 18 m (estimated). UNESCO World Heritage List: Ancient Thebes with its Necropolis also records: “Temple guardians.”
Twin quartzite statues about 18 m tall, carved from blocks quarried near modern Cairo.
What makes it extraordinary
Roman Reconstruction and the End of the Sound
The acoustic phenomenon of the northern colossus reportedly ceased after a reconstruction effort attributed to the Roman Emperor Septimius Severus around 199 AD. In an attempt to curry favor with the oracle, Severus added five tiers of sandstone to the statue's upper half, which had been missing since the 27 BC earthquake. Scholars believe the added weight of these stone tiers likely suppressed the natural vibrations or air movements that caused the sound. The last reliable mention of the statue 'singing' dates to 196 AD, shortly before this structural intervention.
The Acoustic Legend of the Vocal Memnon
Following an earthquake in 27 BC that shattered the northern colossus, the remaining lower half became famous for emitting a 'singing' sound, typically at dawn. Ancient observers like Strabo and Pausanias described the noise variously as a blow, a breaking lyre string, or the striking of brass. This phenomenon led to the statue's erroneous identification with the Greek hero Memnon. The sounds, which attracted Roman emperors and tourists, likely resulted from natural causes such as rising temperatures and dew evaporation within the porous rock, rather than human agency.
Hydrological Context and Site Preservation
Amenhotep III intentionally positioned his mortuary temple on the Nile floodplain, possibly to create a lake in front of the Colossi that served as a water retention reservoir. However, this location led to the temple's long-term degradation, as successive annual inundations eroded the foundations. While the Colossi remained visible—often depicted surrounded by water in 19th-century lithographs—most of the temple's mud-brick structures vanished. Modern excavations by Hourig Sourouzian have since revealed that the complex originally included three pylons, each fronted by colossal statues, and a peristyle court.
Iconography of the Royal Family and Deities
The Colossi feature smaller figures carved into the thrones alongside the pharaoh's legs, representing his wife Tiye and his mother Mutemwiya. A third figure, an unidentified daughter, was originally positioned between his ankles but has since been destroyed. The side panels of the thrones are decorated with relief images of the Nile god Hapi. These artistic details supported Amenhotep III's ideology, which presented him as a 'good god' and a figure of divine status accessible to the public for worship at the temple entrance.
Overland Transport of Quartzite Blocks
The massive quartzite blocks used for the statues were extracted from the el-Gabal el-Ahmar quarry near modern-day Cairo. From this site, the stones were transported approximately 675 kilometers overland to their final destination in Thebes. Historical analysis suggests these blocks were considered too heavy for upstream transport on the Nile, necessitating a significant land-based logistical effort. In contrast, the sandstone used by later Roman engineers for reconstructing the northern colossus is believed to have originated from Edfu, located north of Aswan.
Recent Excavations and Statue Restoration
Extensive restoration and excavation led by archaeologist Hourig Sourouzian have uncovered numerous statues buried by the 1200 BC earthquake, some in pristine condition. As of recent reports, four colossal statues have been re-erected at the site, with eight more awaiting re-erection. Additionally, approximately 200 statues or fragments from the complex are housed in the Luxor Museum for conservation or display. These efforts aim to reconstruct the original layout of the temple, which featured multiple pylons and a court surrounded by columns.
Scale and Material Composition of the Colossi
The Colossi of Memnon are two massive quartzite sandstone statues depicting Pharaoh Amenhotep III in a seated position. Each figure, including its four-meter-high stone platform, reaches a total height of 18 meters and weighs approximately 720 tons. The statues are positioned roughly 15 meters apart and were originally identical, serving as guardians for the pharaoh's mortuary temple. While the southern statue remains a single block of stone, the northern colossus features a lower half with a large crack and an upper section composed of five tiers of different sandstone.
Roman Inscriptions and Imperial Visits
The statues serve as a significant epigraphic record, containing 107 Roman-era inscriptions in Greek and Latin dated between AD 20 and 250. Of these, 61 are in Greek, 45 in Latin, and one is bilingual. Many inscriptions record whether visitors heard the famous dawn sound, including a notable poetic entry by Julia Balbilla during a visit by Emperor Hadrian and Empress Vibia Sabina in November 130 CE. These inscriptions were first studied in detail by Jean-Antoine Letronne in 1831 to connect the site to classical literature.
Guardians of the Theban Necropolis's Largest Temple
The Colossi originally stood at the entrance of Amenhotep III’s mortuary temple, which was the largest and most opulent complex in the Theban Necropolis during its era. Covering 35 hectares, it surpassed the size of the Temple of Karnak at that time and later rivals like the Ramesseum. The statues were intended to allow the public to worship the pharaoh as a 'god-on-earth.' Despite its original grandeur, the temple was largely destroyed by an earthquake around 1200 BC, leaving the Colossi as its most prominent surviving features.
Evolution of the Site's Nomenclature
The modern Arabic name for the site is Kom el-Hatan, though the statues are universally known by the Roman-era name 'Colossi of Memnon.' This name derives from Memnon, a Trojan War hero and son of Eos, the goddess of dawn, due to the statue's dawn-time 'cry.' In the 19th century, local Arabs referred to the individual statues as 'Shama' and 'Tama,' collectively calling them 'Sanamât' or 'the idols.' The entire Theban Necropolis was also historically referred to as the Memnonium, linking the site to the Greek 'Ruler of the West.'
