Do you know if these papyri were dated simply by the occurrence of the name "Khufu" with the assumption that it indicated circa 2500 BCE? I'd love to know how it translates as to whether it refers to an entity "Khufu" that's specifically a human vs. some other entity/organization/construct.
And of course, anyone could have engraved "Khufu" into the blocks in the region at any time throughout history. The engraving is not necessarily contemporaneous with the 4th Dynasty.
