More than 40 years ago, Egyptologist Mark Lehner and geologist Thomas Aigner conducted a study on the Sphinx, the Khafre Valley Temple and the Sphinx Temple, to try and prove the hypothesis that the temple blocks originate from the Sphinx enclosure, and, if correct, it would mean the age of the creation of the Sphinx is likely the same age as the two temples in front of it.
The importance of the study can therefore not be underestimated, especially because, in terms of design, the Sphinx Temple certainly looks to be 4th dynasty, and secondly, thermoluminescence dating that took place in 2013 placed its construction well within the bounds of the 4th dynasty.
Aigner logged each limestone bedrock layer on the Giza Plateau, including those present on the Sphinx core body, recording the lithic qualities and fossil content, and he assigned each limestone layer a number.
Meanwhile, Lehner re-mapped the Valley and Sphinx Temples in detail, numbering each block.
Aigner had identified seven types of limestone at Giza, and these were labelled A to G. Lehner assigned each limestone block in the temples to one of the seven layers, and colour-coded them so we can see where they came from.
According to Lehner, the mapping project seemed to confirm the hypothesis, but even though it's been around 40 years since the scientific project, no hard data and no scientific study has ever been published.
In this video, I show there is reasonable doubt to question what we are told, and unless the data from the geological surveys are published, it is unscientific to accept the idea that the blocks that make up the Sphinx Temple, originated in the Sphinx enclosure.
