Scapulimancy

Scapulimancy (also spelled scapulomancy and scapulamancy, and also termed omoplatoscopy ) is the practice of divination by use of scapulae (shoulder blades). In the context of the oracle bones of ancient China, which chiefly utilized both scapulae and the plastrons of turtle, scapulimancy is sometimes used in a very broad sense to jointly refer to both scapulimancy and plastromancy (similar divination using plastrons). However, the term osteomancy might be more appropriate, referring to divination using bones. Many archaeological sites along the south coast and offlying islands of the Korean peninsula show that deer and pig scapulae were used in divination during the Korean Protohistoric, c. 300 B.C. - A.D. 300/400.

Historically, scapulimancy has taken two major forms. In the first, "apyromantic", the scapula of an animal was simply examined after its slaughter. This form was widespread in Europe, Northern Africa and the Near East. In Northeast Asia and North America however, the second form, "pyromantic" scapulimancy was practiced, involving the heating or burning of the bone and interpretation of the results.

Scapulimancy was also mentioned in Chapter 5 of the Kojiki, the Japanese Record of Ancient Matters, in which the heavenly deities used this process of divination during a consulation by lesser gods.
