Geomancy (Greek: γεωμαντεία, "earth divination") is a method of divination that interprets markings on the ground or the patterns formed by tossed handfuls of soil, rocks, or sand. Geomancy is derived from the roots geo- (Earth) and -mancy (prophecy). Geomancy was one of the original ways to translate Feng Shui, since it predicts things by the elements similar to astrology with the stars.
