   1. A comprehensive name for all of the pretended arts which
      claim to produce effects by the assistance of supernatural
      beings, or departed spirits, or by a mastery of secret
      forces in nature attained by a study of occult science,
      including enchantment, conjuration, witchcraft, sorcery,
      necromancy, incantation, etc.

   2. The art of creating illusions which appear to the observer
      to be inexplicable except by some supernatural influence;
      it includes simple sleight of hand (legerdemain) as well
      as more elaborate stage magic, using special devices
      constructed to produce mystifying effects; as, the magic
      of David Copperfield. It is practised as an entertainment,
      by magicians who do not pretend to have supernatural
      powers.
      [PJC]

   {Celestial magic}, a supposed supernatural power which gave

      produce effects apparently supernatural.

      or express agreement between them and human beings.
