| There are various theories about the dates of his birth and death and they remain uncertain, but many references point out that he died at the age of 68, and by calculating back from the most reliable "Chuyu-ki" entry, dated July 15, 1106, it is mostly likely that he was born in 1039. |
生没とも諸説あってはっきりしないが、68歳で死去とする史料が多く、またその没年は、史料としての信頼性が最も高い『中右記』1106年（嘉承1）7月15日条から逆算し、1039年（長暦3）の生まれとする説が有力である。 |
