Necromancy
NECROMANCY (Gr. vficpofiavrtia., or vdcvofiavrela, from veKpbs or vexus, corpse, and [Mtnela, divination), properly divination by communicating with the dead. The latinized form of the Greek word was corrupted into nigromantia, connecting the word with niger, black, and so was applied to the " black art," " black magic," in the sense of witchcraft, sorcery. This corrupted form is common in English to the 17th century {see MAGIC and WITCHCRAFT).
