Medieval necromancy is believed to be a synthesis of astral magic derived from Arabic influences and exorcism derived from Christian and Jewish teachings. Arabic influences are evident in rituals that involve moon phases, sun placement, day and time. Fumigation and the act of burying images are also found in both astral magic and necromancy. Christian and Jewish influences appear in the symbols and in the conjuration formulas used in summoning rituals.Kieckhefer 2011, pp. 165–166.
