Ten of the papyri are especially very well preserved.[1] The majority of these documents date to the year after the 13th cattle count of Khufu's reign and describe how the central administration sent food and supplies to Egyptian travelers.[1][5] One document is of special interest: the diary of Merer, an official involved in the building of the Great Pyramid of Khufu. Using the diary, researchers are able to reconstruct three months of his life, providing new insight into everyday lives of people of the Fourth Dynasty.[1][5][6] The papyri are the oldest ever found in Egypt.[3]
