Funerary Compositions
From the end of 5th Dynasty onward, religious texts were inscribed in the burial chambers of royal tombs. The oldest surviving compositions, called Pyramid Texts because they were inscribed in pyramid burial chambers, were compilations of spells describing different aspects of the dead king's restoration and existence in the realm of the gods in the afterlife. For some unknown reason, Middle Kingdom rulers did not have any such texts inscribed in the burial chambers of their pyramids. Contemporary private burials, however, had a series of spells, called Coffin Texts because they were inscribed on coffins; many derived from or were influenced by the Pyramid Texts. The first descriptions of the netherworld appear as schematic "maps" on the inner floors on many of these coffins, and are called the Book of Two Ways.
