Four authors from Antiquity have had their detailed descriptions of the Great Pyramid survive to the present day. But Herodotus, Diodorus Siculus, Strabo, and Pliny the Elder all fail to record any mention of the Great Pyramid's upper chamber system.
This video examines why those four authors likely missed the upper chamber system based upon a pattern of deception that spans thousands of years.
We also examine how the Great Pyramid would be experienced by visitors through history, and why their graffiti is often lost to the ravages of time.
Thanks always to my fellow researchers whose efforts contributed to this video, particularly Stefan Bergdoll's writings, Valery Senmuth's photos, and my anonymous pal who has brought to light improved versions of the Edgar Brothers' photographic plates from 1910.
