The Egyptians have always been deeply impressed by the fact of human mortality, and much of their religious belief and religious ritual is taken up with the rites of burial, and detailed doctrines as to the experience of the soul after parting from the body. Their elaborate embalming of the dead springs from the desire to keep the mortal tenement prepared for the soul's return to it. In their Book of the Dead is a full series of prayers, songs, and incantations to be employed at funerals, and by the individual in his journey beyond the tomb. The funeral procession was a very noisy company; lamentations were heard through its whole length, but the burden of the hymns was always, "To the West." This was enlarged upon, "To the West, the dwelling of Osiris; O Chief, as thou goest to the West, the Gods themselves lament, as thou goest to the West."
