Egyptian Book of the Dead
The Egyptian Book of the Dead contains the oldest known religious writings in the world. As it comes to us it is mainly Osirian, but the Osirian group of gods was the latest of all the divine dynasties, although these, as shown at Abydos (by Prof. Flinders Petrie), will account for some ten thousand years of time in Egypt.
The antiquity of the collection is not to be judged by the age of the coffins in which the papyrus rolls were found. Amongst other criteria of length in time the absence of Amen, Maut, and Khunsu supplies a gauge. The presence and importance of Tum affords another, whilst the persistence of Apt and her son Sebek–Horus tells a tale of times incalculably remote.
