Psychomancy

Psychomancy (from ψυχή, soul, and μαντέα prediction) is the pretended art of summoning the souls of the deceased, and learning the future by their communications; it is one of the branches of divination, or mantics. The ancients use only ψυχόμαντις, a sorcerer of this kind, and ψυχομαντειον, the place where such performances took place (oraculum animarum). The same art is called necromancy, and, in a more extensive sense, pneumatomancy. SEE DIVINATION.
