Psychomancy

Webster's Dictionary

(n.) Necromancy.

Cyclopedia of Biblical, Theological and Ecclesiastical Literature

(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).
