Painted scene from the Hunefer’s Book of the Dead (about 1300 B.C.), in the British Museum, London. The Book of the Dead was a large composite of spells, incantations, prayers, and invocations written on a papyrus roll, which were put in the tomb with the mummy. The texts were aimed at ensuring the well-being and protection of the dead in his voyage towards the Land of the Dead, and contained instructions on how to behave in the Afterworld. The images represented the dead himself as he faced the divinities or as he performed cultic acts. This scene shows in sequence the route which the dead is carried through, before being introduced to the presence of Osiris, ruler of the Kingdom of the Dead. Accompanied by Anubis, the dead attend to the “Weighing of His Heart”, which was evaluated as against justice and truth (Maat, the concept of cosmic order represented by a feather put on the other plate of the balance). The next step was to come near Osiris’s throne, accompanied by the god’s son, Horus.
