The inscribed walls of the inner chambers and corridors of Pepy Ist's pyramid, the third Pharaoh of the VIth Dynasty (c. 2330-2280), offer the largest set of Pyramid Texts known. Based on the previous publication of these texts in facsimiles (MIFAO 118/1-2), a 2nd edition of which came out in 2010., the present translation includes additional material, especially from Merenre's and queen Ankhesenpepy II's pyramids, the last one discovered in 2000 by the French-Swiss archaeological Mission of Saqqara (MafS). The translation of about 800 spells, including 81 "new" ones (PT 1001-1081), is preceded by a general presentation of the whole corpus.
