Compare mantic systems
Read systems against shared questions to identify common language, procedural differences and distinct limits.
| Dimension | 蓍筮与《周易》 ↗ | 数字卦与先秦筮法 ↗ |
|---|---|---|
| Family | Divination and correlative foundations | Divination and correlative foundations |
| Inputs | Procedure edition, operation log and line values | Published plate, number sequence and scholarly reading |
| Procedural structure | 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. | Different sources correlate generated numbers with directions, body parts, topics or positions. The Tsinghua Shifa offers unusually complete tables and judgment structures but does not represent every pre-imperial method. |
| Formation | Layered formation from Western Zhou through the Warring States | Shang-Zhou through the Warring States |
| Evidence labels | Excavated evidence · Textually documented · Traditional attribution | Excavated evidence · Textually documented |
| Texts | Zhou Changes and its Wings / Divination accounts in the Zuo Tradition and Discourses of the States / Tsinghua bamboo manuscript Shifa | Tsinghua Shifa / Chu divination and sacrificial manuscripts / Shang-Zhou objects bearing numerical hexagrams |
| Limits | 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. | Not every numerical hexagram belongs to the received Zhouyi, and visual resemblance alone cannot prove that a complete bagua system existed in prehistory. |
| Research question | How do moving-line conventions change the passage selected? | Which assumptions turn a numerical sequence into lines? |
