Psephomancy is a mystical practice where divination is performed using pebbles or stones. This ancient technique is believed to have originated in ancient Greece and was used by spiritual leaders to predict future events. While psephomancy is a unique term, there are several synonyms for this practice. Some of these include lithomancy, which involves divination using stones, and gastro-mancy which uses prophetic utterances produced by the stomach. Another term closely associated with psephomancy is alomancy, which involves divination using salt. Psephomancy may be rare, but these synonyms clearly demonstrate that it belongs to a larger category of divination practices that have valued their unique mediums.
