By 2500 years ago, the pyramids' smooth limestone casings were already largely missing. Greek historian Herodotus described the Great Pyramid as tiered in the 400s BC. In 1638, John Greaves documented Khafre still had most of its casing intact — a rare glimpse into their condition before modern study. A 1610 drawing shows Khufu pyramid with no casings and Khafre with some top casings. Diodorus Siculus in the 1st century BC also described the pyramid as tiered. Greek visitors noted darker stones at the base of Khafre and Menkaure, distinguishing the original casing from core masonry.
