To investigate when the damage occurred, it is crucial to scrutinize historical accounts. Classical historians Diodorus Siculus and Pliny the Elder provided detailed descriptions of the Great Pyramid in the first century BC and AD, respectively. Both reported a flat summit and provided measurements that align surprisingly closely with modern evaluations. Analyzing these accounts, we can infer that the pyramid's summit was likely flat as early as the first century, with further investigations suggesting a gradual removal of stones over centuries.
