Are there any Roman-Egyptian accounts of how the pyramids were built?

by Resented_Brute

This may seem like a dumb question, but i couldn't find anything which touches on this subject so far. During the Ptolemaic Dynasty, did they know how old the Giza Pyramids were, how it was built, who built it and for what purpose?

And what about when Egypt was once a Roman Province, what exactly did they tell the Romans about the pyramids?

Yes. I wrote about this in Is it true that "two hundred years after the last pyramid was reared in their country, Egyptians were as baffled by the big masonries as everyone else?" In other words, did they forget how to build the pyramids? How/why?
