The text of the Instruction to Merikare was preserved in three fragmentary papyri. The oldest, dating from the second half of the XVIIIth Dynasty (ca. 1539 - 1292 BCE), the so-called « Papyrus St.-Petersburg 1116A », is the most complete, but also the most corrupt, with numerous lacunae and many scribal errors. Papyrus Moscow 4658 dates from the end of the XVIIIth Dynasty, while Papyrus Carlsberg 6 may even be later. cf « The Royal Instruction of Khety to Merikare » (consulté le )
