نصوص الأهرام
The Pyramid Texts originally appeared in the Pyramid of Unas at the end of the Fifth Dynasty initiating a tradition that carried on in the pyramids of the kings and queens of the Sixth through Eighth Dynasty, until the end of the Old Kingdom. The texts in Pepi I's pyramid, comprising 2,263 columns and lines of text, are the most extensive such corpus of texts from the Old Kingdom. Though the tradition of writing pyramid texts had started in Unas' pyramid, they were originally discovered in Pepi I's pyramid in 1880.
