In Kemet, the priests often compiled an individualized book for each ruler at their death, called the “Book of Going Forth by Day”. This book is more commonly known as the Book of the Dead. It usually contained declarations and spells to help the deceased in their afterlife. The “Book of the Dead” for scribe Ani from Thebes is the manuscript called the Papyrus of Ani.
This aspect of African funerary literature which is often mistaken for a codified ethic of Ma’at, is Spell (Chapter) 125 of the Book of the Dead or Papyrus of Ani. The lines of this spell are often collectively called the “Forty-Two Declarations of Purity” or the 42 Negative Confessions.
These declarations varied somewhat from tomb to tomb. Seemingly depending on the time of reign. They also appear to express each tomb owner’s individual conception of Ma’at, as well as working as a magical absolution—misdeeds or mistakes made by the tomb owner in life could be declared as not having been done, and through the power of the written word, wipe that particular misdeed from the afterlife record of the deceased.
Many of the lines are similar, however, and they can help to give the student a “flavor” for the sorts of things which Ma’at governed — essentially everything, from the most formal to the most mundane aspects of life.
The doctrine of Ma’at is represented in the declarations to Rekhti-merti-f-ent-Maat and the 42 Confessions listed in the Papyrus of Ani.
