Compare mantic systems

Read systems against shared questions to identify common language, procedural differences and distinct limits.

Read differences by dimension; historical evidence labels do not imply predictive validity.

InputsRubbing, transcription, catalogue number and dating proposalProcedure edition, operation log and line values
Procedural structureA diviner drilled or grooved the medium and applied heat before reading the resulting cracks. Late-Shang inscriptions may record date, charge, prognostication and verification, placing question, judgment and outcome in one archival chain.The received yarrow procedure repeatedly divides, sets aside, counts by fours and collects remainders to obtain line values six through nine. The primary hexagram, changing lines and resulting hexagram form the interpretive object.
FormationPrehistoric precedents; mature royal institution in the late ShangLayered formation from Western Zhou through the Warring States

LimitsOracle-bone divination should not be equated with Zhouyi divination, and its rules of crack interpretation can be reconstructed only in part.The lineage of Fuxi, King Wen, the Duke of Zhou and Confucius is an influential traditional genealogy, not a straightforward conclusion of modern textual history.
