How the evidence for Abe no Seimei and Onmyōdō Divination changes
The date of a document and the date of an interpretation are recorded separately.| Witness or edition | Date | Editorial status | Why it matters |
|---|---|---|---|
| Encyclopaedia Britannica · Abe no Seimei | 921–1005 onward | Baseline source | Court records, ritual manuals and medieval legends belong to different periods. |
| Scholarly or institutional interpretation | Later review | Context layer | Explains language, history and uncertainty without becoming the original text. |
| Viral quotation or modern event match | Recent circulation | Derivative layer | Most vulnerable to translation drift, omitted failures and hindsight; compare with Encyclopaedia Britannica · Abe no Seimei. |

Where interpretation changes
The main dispute concerns the distance between 921–1005 onward and Court specialist · medieval tale · modern media icon. Translation, selective quotation, changed definitions and hindsight can make a broad record appear more exact than it was. Competing readings are therefore preserved rather than silently merged.10 · EVIDENCE SCORE & PROVISIONAL CONCLUSION
