ABSTRACT
Egypt has a fair number of monuments, in Lower Egypt the climate of the Delta is responsible for irreparable destruction, which deprives us of direct evidence about the region which sent forth the ideas and doctrines which expanded in later ages. Thanks to the Pyramid Texts, we have been able to work backwards to a tentative account of these doctrines. Much remains to be done in this matter* The reader has been warned that this period of elaboration was of exceptional importance and very long ; it includes the date of the inauguration of the calendar (4241) and ends on the accession of Menes (about 3315).
