Theomancy in the ancient world was a form of divination by oracles believed to be divinely inspired. However in the Jewish Kabbalah, theomancy studies the mysteries of the divine majesty and seeks the sacred names. The one who possesses the science knows the future, commands nature, has full power over angels and demons, and can perform miracles. The Rabbis claimed that it was by this means that Moses performed so many miracles; that Joshua was able to stop the sun; that Elias caused fire to fall from heaven, and raise the dead; that Daniel closed the mouths of lions; and that the three youths were not consumed in the furnace. However, even though experts in the divine names, Jewish rabbis no longer perform any of the wonders done by their fathers. A.G.H.
