Study suggests that nature played a role in the origins of the Great Sphinx
The Great Sphinx of Giza is a limestone statue of a reclining sphinx, a mythical creature characterised by the combination of a human head and a lion’s body.
The Great Sphinx is the oldest known monumental sculpture in Egypt, standing on the Giza Plateau on the west bank of the Nile in Giza,
Based on archaeological evidence, the construction of the Great Sphinx dates back to approximately 2500 BC during the reign of Pharaoh Khafre, who oversaw the construction of the Second Pyramid at Giza.
Many mysteries enshroud the Great Sphinx, including its original appearance and the symbolism it was intended to convey. Surprisingly, there has been relatively little focus on the study of what the landscape was like before its creation and how the natural environment may have influenced its design.
In a new study by researchers from New York University (NYU), scientists have replicated conditions that existed 4,500 years ago to demonstrate how wind moved against rock formations that could have shaped the monument.
“Our findings offer a possible ‘origin story’ for how Sphinx-like formations can come about from erosion,” explains Leif Ristroph, an associate professor at New York University’s Courant Institute of Mathematical Sciences and the senior author of the study, which has been accepted for publication in the journal Physical Review Fluids. “Our laboratory experiments showed that surprisingly Sphinx-like shapes can, in fact, come from materials being eroded by fast flows.”
The study centred on duplicating yardangs, distinctive rock formations found in deserts formed by the accumulation of wind-blown dust and sand. According to the researchers, there is the possibility that the Great Sphinx may have initially started as a natural yardang, later enhanced and sculpted by humans into the iconic monument we know today.

To support this theory, the study authors from NYU’s Applied Mathematics Laboratory worked with soft clay mounds containing embedded less erodible material, simulating the landscape of northeastern Egypt where the Great Sphinx is located.
They then subjected these formations to a rapid-flowing water stream, mimicking the erosive action of wind, which gradually carved and reshaped them, eventually leading to the emergence of a structure resembling the Great Sphinx.
The harder or more resistant material within these mounds took on the role of forming the “head” of the lion, while various other features, including a sculpted “neck,” “paws” resting on the ground in front, and an arched “back,” began to take shape.
“Our results provide a simple origin theory for how Sphinx-like formations can come about from erosion,” observes Ristroph. “There are, in fact, yardangs in existence today that look like seated or lying animals, lending support to our conclusions.”

Pleistocene hunter-gatherers settled in Cyprus thousands of years earlier than previously thought
Archaeologists have found that Pleistocene hunter-gatherers settled in Cyprus thousands of years earlier than previously thought.
An analysis of the oldest archaeological sites on the island suggests that the first human occupation occurred between 14,257 and 13,182 years ago.
This analysis, published in the journal Proceedings of the National Academy of Sciences, used archaeological data, climate estimates, and demographic modelling.
The demographic modelling indicates that these early groups consisted of hundreds to thousands of people, who arrived in two to three main migration events over a period of only 100 years. Within just a few centuries, 11 generations – the population of Cypris had expanded to up 4,000 to 5000 inhabitants.
According to the study authors, these findings refute previous studies that suggested Mediterranean islands would have been unreachable and inhospitable for Pleistocene hunter-gatherer societies. “This settlement pattern implies organised planning and the use of advanced watercraft,” says Professor Bradshaw.
The climate estimates suggest that these early settlers arrived at a time during an increase in temperature and precipitation, also enabling an increase in environmental productivity that could sustain large hunter-gather populations.
Dr Moutsiou, said: “It has been argued that human dispersal to and settlement of Cyprus and other eastern Mediterranean islands is attributed to demographic pressures on the mainland after abrupt climatic change saw coastal areas inundated by post-glacial sea-level rise, forcing farming populations to move to new areas out of necessity rather than choice.”
Our research, based on more archaeological evidence and advanced modelling techniques, changes that”, adds Dr Moutsiou.
The research – “Demographic models predict end-Pleistocene arrival and rapid expansion of pre-agropastoralist humans in Cyprus” by Corey Bradshaw, Christian Reepmeyer, Frédérik Saltré, Athos Agapiou, Vasiliki Kassianidou, Stella Demesticha, Zomenia Zomeni, Miltiadis Polidorou and Theodora Moutsiou – has been published in the Proceedings of the National Academy of Sciences of the USA.

A groundbreaking study, published in the journal Communications Earth & Environment, has revealed why the largest concentration of pyramids in Egypt were built along a narrow desert strip.
Since the beginning of the Pharaonic era, the Nile River has played a fundamental role in the rapid growth and expansion of the Egyptian civilisation.
The Nile provided sustenance and functioned as the primary mode of transportation for goods and building materials, which explains why most of the main cities of the Egyptian civilisation were built in close proximity to the banks of the Nile and its peripheral branches.
Over the centuries, the primary channel of the Nile shifted laterally, causing these peripheral branches to silt up. As a result, population centres were cut off from the vital resources the river provided.

This is apparent with the pyramids along the Western Desert Plateau, where a majority of the pyramids are concentrated along a narrow desert strip several kilometres from the current primary channel of the Nile.
Using a combination of radar satellite imagery, geophysical data, and deep soil coring, the study has investigated the subsurface structure and sedimentology in the Nile Valley adjacent to the pyramid clusters.
This has revealed an extinct branch of the primary channel called the Ahramat Branch, which was connected to the pyramids of the Old and Middle Kingdoms via causeways and their Valley Temples.
According to the study authors: “The Ahramat Branch played a role in the monuments’ construction and was simultaneously active and used as a transportation waterway for workmen and building materials to the pyramids’ sites.”
The eastward migration and abandonment of the Ahramat Branch could be attributed to gradual movement of the river to the lower-lying adjacent floodplain or tilting of the Nile floodplain toward the northeast as a result of tectonic activity, as well as windblown sand incursion due to the branch’s proximity to the Western Desert Plateau.
