Why here

An annual, predictable flood laid new silt across a narrow strip of otherwise lethal desert. Agriculture was reliable enough to support specialists, and the desert on both sides did the work of a standing frontier.

Egypt is a ribbon. Habitable land is a few kilometres wide in most of the valley, widening only in the Delta and the Faiyum, and everything outside it is desert that kills the unprepared.

The inundation arrived in late summer, carried silt from the Ethiopian highlands, and withdrew in time for planting. Nilometers measured it because tax assessment depended on it: a low flood was a fiscal event before it was a famine.

The river also ran the wrong way for a highway, which turned out to be an advantage. The current carried boats north; the prevailing wind pushed sails south. A stone barge could make a round trip under natural power alone.

One of the longest continuous state records in human history, with monumental engineering documented in its own administrative texts.

  • What ended the Old Kingdom — climate, politics, or both?
05 · Known & unknown

Where the evidence stops

What we know
  • Pyramid workers were housed, fed and organised by the state — bakeries, breweries and a labour settlement have been excavated at Heit el-Ghurab.
  • The Merer papyri record actual limestone shipments to Giza, dated to Khufu's reign.
  • Hieroglyphs were deciphered from bilingual texts and are read with high confidence today.
What we think
  • Ramp systems were probably composite — straight, zigzag and internal solutions used at different heights.
  • The Old Kingdom's end involved a drying trend interacting with political fragmentation rather than either cause alone.
What we don't know
  • The precise geometry of the construction ramps.
  • What is inside the ScanPyramids 'Big Void'.
  • Total workforce at peak, and its rotation schedule.
