The Old Kingdom of Egypt (circa 2613-2181 BC) is otherwise called the 'Age of the Pyramids' or 'Age of the Pyramid Builders' as it incorporated the great fourth Dynasty when King Sneferu idealized the craft of pyramid building, and the pyramids of Giza were developed under the rulers Khufu, Khafre, and Menkaure. The verifiable records of this period, the fourth, sixth Dynasties of Egypt, are scant, and antiquarians respect the historical backdrop of the time as in a real sense 'written in stone' and generally compositional in that it is through the landmarks and their engravings that researchers have had the option to develop a set of experiences. The actual pyramids transfer sparse data on their developers. However, the morgue sanctuaries fabricated close by, and the stelae which went with them give the ruler's names and other significant data.
