Pyramid of Pepi I

The Pyramid of Pepi I is the funerary monument of the Sixth Dynasty pharaoh Pepi I, built in the 24th or 23rd century BC, and it lent its name to the ancient Egyptian capital city of Memphis. Like the pyramids of his predecessors, its substructure is inscribed with vertical columns of the Pyramid Texts, which were discovered here in 1880 by Gaston Maspero even though the tradition of inscribing them originated earlier in the pyramid of Unas. Pepi I's pyramid holds the largest surviving corpus of these texts from the Old Kingdom, comprising 2,263 columns and lines of hieroglyphs.
