Necromancy
Nec′ro·man′cy (·sy̆), n. [OE. nigromaunce, nigromancie, OF. nigromance, F. nécromance, nécromancie, from L. necromantia, Gr. νεκρομαντεία; νεκρός a dead body (akin to L. necare to kill, Skr. na(?) to perish, vanish) + μαντεία divination, fr. μάντις diviner, seer, akin to E. mania. See Mania, and cf. Internecine, Noxious. The old spelling is due to confusion with L. niger black. Hence the name black art.] The art of revealing future events by means of a pretended communication with the dead; the black art; hence, magic in general; conjuration; enchantment. See Black art.
