Scapulimancy (also spelled scapulomancy and scapulamancy, also termed omoplatoscopy or speal bone reading) is the practice of divination by use of scapulae or speal bones (shoulder blades). It is most widely practiced in China and the Sinosphere as oracle bones, but has also been independently developed in other traditions including the West.
