Claims › Egypt: Sphinx & Giza dating › The Fourth Dynasty completed an older Giza site (the 'legacy' or restoration hypothesis)

The Fourth Dynasty completed an older Giza site (the 'legacy' or restoration hypothesis)

Status: Leading Edge Verdict: Open question: the built pyramids date to the Old Kingdom; no dating method has yet reached the bedrock and underground parts

The claim: The Giza pyramids were largely built in the Old Kingdom, but on an older plan and older foundations: the bedrock mound, the Great Pyramid's underground chamber and an early form of the Sphinx go back thousands of years earlier, perhaps to about 10,500 BCE.

Where the evidence stands: This is Graham Hancock's current position, and it is close to Robert Schoch's. Neither argues that the pyramids as we see them were built in the Ice Age. Radiocarbon dates from the mortar, the papyri of Khufu's inspector Merer and the workers' town all place the masonry in the Fourth Dynasty. But no published date reaches the bedrock core, the underground chamber or the oldest cut faces, and the one dated object from inside the pyramid is about 500 years older than Khufu. The question is therefore open rather than settled.

Background

Hancock wrote in 2016 that the Giza pyramids were 'most likely substantially built during the old Kingdom, but on much older foundations' and that this had been his position since Fingerprints of the Gods (1995). In Magicians of the Gods (2015) he proposes that the Subterranean Chamber, the bedrock hill inside the Great Pyramid and early work on a lion-headed proto-Sphinx date to around 10,500 BCE, with most of the building done around 2500 BCE. He reads Merer's papyri, which record Tura limestone shipped to the pyramid late in Khufu's reign, as records of finishing work on the casing. Egyptologists see one continuous building programme growing out of earlier pyramids at Meidum and Dahshur. See also the radiocarbon claim, the Sphinx water-erosion claim and the Orion correlation.

What has been measured

Dates, measurements and documented findings, kept separate from interpretation.

Proponents' main arguments and cited evidence

  • Hancock argues that the bedrock mound and the rough Subterranean Chamber belong to an earlier phase, and that the Fourth Dynasty completed an older plan rather than starting a new one. [1][2]
  • Schoch has said the main pyramids 'were built over or enhanced or restored older structures' and that the Subterranean Chamber 'goes back much earlier'. [3]
  • Hancock reads the Merer papyri as recording the finishing of the casing, which fits their late date in the reign. No existing date tests the bedrock-cut parts. [2][4][5]

The mainstream position and its evidence

  • The mortar's radiocarbon dates, the workers' town and the papyri all point to a single Fourth Dynasty building programme. The offsets in the dates are centuries, not millennia. [4][5][7]
  • Earlier pyramids at Meidum and Dahshur show a step-by-step development of the techniques used at Giza, which Egyptologists see as evidence against an inherited older plan. [7]
  • The Inventory Stela, which says Khufu found an older temple and the Sphinx already standing, was carved in the Late Period, some two thousand years after Khufu, and contains anachronisms. Most Egyptologists read it as later priestly tradition, although Schoch and a co-author argue it preserves real memory. [8][9]

What evidence would help settle it

Cosmogenic-nuclide exposure dating of the bedrock-cut faces in the Subterranean Chamber and the Sphinx enclosure, luminescence dating of sealed sediments, and radiocarbon dating of short-lived plant material from inner joints would test the hypothesis directly. None has been published.
