2. Ancestor-worship.--A set of beings of a very different kind comes next. If man found in the world which he beheld outside him a number of objects he could make gods, his domestic experience forced him to consider certain beings of a different kind, of whom the outward world could tell him nothing. The worship of the dead, of ancestors, is diffused throughout nearly the whole of antiquity, it is practised by most savages. Man at an early stage does not fully realise the meaning of death. He interprets death after the analogy of dreams, in which he judges that the spirit leaves the body and traverses distant regions, coming back to the body again when the journey is ended. A vision is to him an instance of the same thing. He sees a friend, who, he afterwards learns, was far from him at the time, and he judges that it was the spirit of his friend which visited him. Thus there arises in his mind the conception of a human spirit which is able to leave the body and dwell at a distance from it. It is called by various names,--the shade, the image, the heart, as perhaps when Elisha says his heart went with Gehazi when he went to meet Naaman the Syrian (2 Kings v. 26), the breath, the soul. When the breath or spirit goes away and stays away (in spite of efforts made to bring it back) the man dies. But the spirit is not dead. It has gone away and is staying somewhere else. The spirit resembles the body in shape, but it is of a thin and light consistence, and is able to move about and to pass through the smallest openings, to make unpleasant noises, and to cause its presence to be felt in a variety of ways. In the very earliest times, the savage regards the spirit which has left the house as an enemy, and uses a variety of precautions to keep it from coming back to trouble him (vampires, ghosts, _lemures_). Whether from such fear or from more liberal motives, much is done to please the spirits of the departed and to increase their comfort in the abodes to which they have gone. At their burial or cremation all they may be supposed to want where they are going, _i.e._ the things they used on earth, are made to accompany them; food and weapons are placed beside them; servants are killed whose spirits are to wait on them, even a wife, voluntarily or without being asked, gives up her earthly life to accompany her husband. Offerings of food and drink are made to them afterwards, prayers are addressed to them, memorials of them, of various kinds, are preserved in the houses they occupied.
