Scapulomancy (scapulamancy, scapulimancy), Spatulamancy (not to be mistaken with Spatalamancy), armomancy, or Omoplatoscopy is a form of Pyromancy practiced in ancient Babylon and elsewhere. The cracks in the shoulder blades of animals (usually sheep) burned in sacrificial fires were interpreted.
This was called Spealomancy in Scotland where they referred to this form of divination as reading the Speal-bone.
