How the Great Pyramid at Giza Looked in 2560 BCE
The article states "smooth layer of fine white limestone on the outside" and that the current outer rough surface is due to "hundreds of years of pollution and weathering".It was my understanding that the outer surface was polished marble, and that it was removed by looters, not natural degradation. But I haven't been able to find a good source, aside from https://www.reddit.com/r/history/comments/cxgj96/what_happen...
