What Is Osteomancy?
Another form is pyro-osteomancy when the seer predicts the future based on the cracks in an animal bone - often the shoulder blade (scapula) after it has been burned in a fire. This practice is most often associated with the Chinese. The earliest pyro-osteomancy in China included the bones of sheep, deer, cattle, pigs and turtle shells. However, pyro-osteomancy was widespread. It is also known from prehistoric east and northeast Asia, and from North American and Eurasian ethnographic reports.
