The Pyramids of Giza

The three pyramids at Giza are the surviving apparatus of a state theology in which the pharaoh, at death, was not simply buried but transformed.

The Fourth Dynasty project

The complex was raised across roughly three generations of the Fourth Dynasty, about 2600 to 2500 BCE, for Khufu, his son Khafre and his grandson Menkaure. Khufu's Great Pyramid, originally about 146 metres, held the record for the tallest human-made structure for some four thousand years. Each pyramid was only the centre of a larger machine: a valley temple by the river, a causeway climbing to a mortuary temple against the pyramid's east face, and satellite pyramids and boat pits, one of which held a disassembled cedar barque now reconstructed.

What the king became

The theology is legible in the older Pyramid Texts of the following dynasties, which describe the dead king ascending to join the circumpolar "imperishable stars" that never set, and merging with the sun god Ra whose daily circuit the pyramid's solar geometry echoes. The Great Sphinx, a lion with a royal head carved from the bedrock beside Khafre's causeway, was later worshipped as a form of the sun god Horemakhet. The precision of the work, the near-cardinal orientation and the internal shafts, has fed four thousand years of speculation, most of it running well ahead of the evidence for what were, in the first place, tombs.

After the pharaohs

The plateau drew visitors continuously: New Kingdom pilgrims who left the Sphinx a temple, Greek and Roman tourists who counted the pyramids among the seven wonders, and medieval and modern scholars. Only Giza's pyramid survives of the seven wonders. The site is a working archaeological zone and one of the most visited monuments on earth, administered by Egypt's antiquities authority.

Building the pyramids meant moving stone at a scale Egypt never repeated, and the clearest record of how comes from a diary, not a monument.

The logbook of Merer

In 2013 papyrus fragments were found at Wadi al-Jarf, a Red Sea harbour, recording the work of a mid-ranking official named Merer in about the twenty-seventh year of Khufu's reign. His team hauled fine white limestone by boat from the quarries at Tura, across the river and up a canal, to "Akhet-Khufu", the pyramid under construction. It is the oldest inscribed papyrus known, and the only firsthand account of building the Great Pyramid that exists.

Who did the lifting

Excavation of a workers' settlement south of the plateau, led by Mark Lehner and Zahi Hawass, found bakeries, breweries and cattle bones on a scale suggesting rationed provisioning rather than casual labour, alongside a nearby cemetery of workers buried with some care. That evidence has displaced the old picture of slave gangs with one of rotating conscripted crews, fed and housed for the duration of a shift.

What is still guessed at

How the blocks reached height is unresolved. Internal spiral ramps, an external straight ramp, and combinations of both have all been proposed; no ramp survives intact to settle it, and the papyri describe delivery to the site, not the final lift.

Giza did not stop being religious when the Fourth Dynasty ended. More than a thousand years after the pyramids were finished, the Great Sphinx had been buried to the neck in sand and was being worshipped under a new name as a form of the sun god, by people who no longer knew which king had built it. A New Kingdom prince cleared the sand, set up a carved stone between the paws recording a dream in which the god promised him the throne in exchange, and a small temple grew up on the spot. That is a second religion practised on top of the first, in the same place, with the original meaning largely lost.

The pattern repeats. Classical visitors treated Giza as one of the wonders of the world and left graffiti; medieval writers explained the pyramids as granaries or as libraries of antediluvian knowledge; and from the nineteenth century a steady stream of modern esoteric movements has attached its own claims to the Great Pyramid's dimensions. The atlas records these as later uses of the site rather than as evidence about what its builders intended. The reason the distinction matters is that the builders left their own evidence. The Pyramid Texts, carved in slightly later royal tombs, and the layout of the complexes themselves say what the pyramids were for, and it is not what most of the later theories propose.
